Sigrid Heuer

Meet Sigrid Heuer (pictured), a Molecular Biologist and Senior Scientist at the International Rice Research Institute (IRRI). Her lively and riveting story will take us from Africa through her native Europe and on to Asia, and finally Down Under to Australia.

Origins – the African chapter
Africa holds a special and soft spot in Sigrid’s love affair with science: it was while on this continent that she realised her calling in life as a scientist – linking people doing pure research on plant genes to help plants survive and even thrive in harsh environments, with people who want to apply that knowledge to breed crops that can change the lives of millions of farmers who constantly compromise with nature to make a living.

Fieldwork: Sigrid at a field trial for rice phosphorus uptake.

“Working as a postdoc at the Africa Rice Center in Senegal was a real life-changing experience,” Sigrid recollects with great fondness. “It’s where I found my niche, using my background in theoretical science and applying it to developing crops that could overcome abiotic stresses, and in doing so, make a real impact on people’s lives.”

Rowing further down the river: from upstream to downstream science
Sigrid was born and raised in Hamburg, Germany. She remembers wanting to be a psychologist and didn’t consider science until a few years after finishing school. After completing a biology undergraduate at Phillips University, Marburg, Germany, she returned to her home city of Hamburg to complete a Masters and PhD in plant physiology and molecular biology respectively.

“Back then, I was really involved in upstream science, fascinated in the fine details without much consideration of how such research could benefit society,” says Sigrid. “I still enjoy this form of science and really do value its purpose, but putting it into practice and focusing on the impact that it can have is what really motivates me now.”

Moving to IRRI, and meeting Pup1 and GCP
After three years in Senegal, Sigrid moved to the Philippines to join IRRI in 2003, first as a consultant then as a part-time scientist. In these early years, she was working on several projects, one of which was the GCP-funded Pup1 (rice phosphorus uptake) project.

“The project sought to identify the genes associated with phosphorus uptake in rice lines that could tolerate phosphorus-deficient soils,” says Sigrid. “It was an interesting project in which I was able to use my background in molecular biology. Little by little, I got more and more involved in the Pup1 project and after a year I was asked by Matthias Wissuwa, who was leading the project at the time, if I wanted to take it over. It was a great opportunity which I jumped at, not knowing then how challenging it would prove.”

Pup1 was the first major project I had managed. It was a playground of sorts that allowed me to learn what I needed to know about managing a project – writing proposals and reports, managing budgets and people’s time, and everything else that comes with leading a team.

The ‘root’ and  ‘command post’ where it all happens: Sigrid in the office. For the benefit of our readers, we would have credited the young artist whose colourful work graces the background below the bookshelf, but we were too polite to pry and prise out the young talent’s name, having hogged too much of Sigrid’s time already!

Learning to lead – both work and play

Over the last seven years, Sigrid has been a Principal Investigator and joint leader of the project, which has given her latitude to mature professionally, and not just in science alone. “It’s been tough but personally fulfilling,” Sigrid says, with just a touch of exhaustion.

Pup1 was the first major project I had managed. It was a playground of sorts that allowed me to learn what I needed to know about managing a project – writing proposals and reports, managing budgets and people’s time, and everything else that comes with leading a team. I was really lucky to have Matthias’ help as well as the other experienced collaborators and networks. However, the main factor that made my job a lot less stressful, was the benefit of long-term funding and support from GCP. GCP was always there, supporting us and giving us confidence even when we weren’t sure we were going to succeed.”

Persistence pays: tangible products, plus publication in Nature
In August 2012, Sigrid and her team achieved what they had set out to do seven years ago, through what Sigrid puts down to sheer persistence: their discovery of the Pup1 gene was recognised by their scientific peers and published in the highly renowned journal,  Nature.

Sigrid (3rd left) at the lab with other colleagues in the phosphorus uptake team.

“Having our paper published is really something special and personally my greatest achievement to date,” says Sigrid, but she is also quick to add that it was a team achievement, and that the achievement was in itself humbling.

“It was a double reward for persisting with the research, and with getting it into Nature. We wanted it in Nature for several reasons. To raise awareness on phosphorus deficiency and phosphorus being a limited resource, especially in poorer countries; and to draw attention to how we do molecular breeding these days, which is a speedier, easier and cost-effective approach to developing crops that have the potential to alleviate such problems.”

Sigrid hopes the article will have a lasting impression on readers, and encourage funders to continue to support projects that have such impact on the lives of end-users.

What next? Technology transfer, transitions and torch smoothly passing on…
With the Pup1 gene now found, IRRI researchers are working with breeders from country-based breeding programmes around the world to help them understand the techniques to breed local varieties of rice that can grow in phosphorus-deficient soils. They are also collaborating with other projects that wish to use the Pup1 project as a case study for phosphorous deficiency tolerance in other crops like maize, sorghum, and wheat (see an example here, that includes partners from Africa and Latin America).

Sigrid sees this next stage as a perfect time to step down from the project: she plans to move to Adelaide, Australia at the end of 2012 to lead a new project that is looking at drought and nitrogen deficiency tolerance in wheat.

“Matthias passed the baton on to me, and now I get to pass the baton on to someone else, so it’s nice. And I’ll be sure to always be around to help them too.”

The TLI project lets us know about molecular breeding, so it’s exposed us to new developments in science, especially in the application of molecular techniques and plant breeding.”  Asrat Asfaw Amele, Southern Agricultural Research Institute, Ethiopia

Many a tale about Ethiopia will regale the reader with details of its contrasting landscape, numerous rivers, searing regional temperatures, the multicultural makeup of its society, its world-famous, unbeatable long-distance and high-altitude runners, its rich history and culture; a sweet producer of honey, the home of coffee, and origin of all mankind…

Seeing red… but no blood
…I found a land of incurably hospitable and kind people, proud of their country and culture; infectiously good music, incredibly strong coffee, where they love both bloody raw meat and protein-rich red beans, dubbed ‘bloodless meat’ in this part of the world.

Cool early morning departure

Cool early morning departure

Out & about
My first real taste of Ethiopia was out in the countryside where I visited the work of GCP’s Tropical Legumes I (TLI) project in the field, on a trip to the bean fields at the Southern Agricultural Research Institute’s (SARI) research stations at Areka and Hawassa, which took us on a 600-km round tour, out of the capital Addis Ababa and into the Great Rift Valley beyond.

We set off early that cool morning, and as we headed into the countryside, I glimpsed many a local taking their first breath of morning air as they stepped outside from their decoratively-painted, round, thatched-roof homes, and shook the night’s sleep from their shoulders.

Traditional thatched living rooms

Traditional thatched living rooms

So their day began – already there was smoke coming from the chimneys, and I imagined the lady of the house beginning to prepare for the first coffee ceremony of the day. Coffee is often accompanied by a dish of boiled red beans. Or maybe she was warming the pan for the morning injera – a kind of ‘teff tortilla’: a sour-dough thin pancake made of the local cereal, teff. Injera is an iconic ubiquitous component of Ethiopian cuisine, with which diners take all manner of wat, or stew made from a rich variety of ingredients – from legumes to raw meat, carefully rolling the spongy crepe around the filling twice, making sure no food falls onto the fingers, for dining etiquette strictly dictates against the licking of fingers.

Ensete plantations

Ensete plantations

Living landscape

We pass score upon score of the gently-smoking thatched round huts – the traditional ‘living rooms’ in these parts; most dwellings are accompanied by modest smallholdings, with maybe a grazing goat or two, and many more with plantations of ensete – a banana-like plant, which, in spite of its inedible fruit, has long been a staple in Ethiopia. It is used for its root, which is mashed to make a tasty, stodgy, bread-like food called kocho, used to accompany meals, a denser cousin of the favourite injera. These smallholdings would also be the perfect size for cultivating beans, as they are not an acre-hungry crop, but grow happily on small plots of land, and in some areas are intercropped with ensete to maximise the space.

Dromedaries, drought and beans

Our common legume: the bean, Phaseolus vulgaris L

Our common legume: the bean, Phaseolus vulgaris L

Into this landscape we pass the incongruous addition of a herd or two of camels with their owners…significantly peculiar as these aren’t desert lands, but the edge of the Ethiopian highlands, gradually and graciously giving way to the majestic Great Rift Valley below. I ask my guide about the addition of camel hands to this highland scenery: he explains their strange presence is due to a growing food shortage which has forced these nomadic peoples further afield to find their fare. The appearance of these dromedaries and their human partners brings harshly to mind Ethiopia’s most notorious claim to fame – especially for anyone who recalls the mid-1980s – for whom Ethiopia will always be indelibly synonymous with famine. It also throws the work of GCP, and specifically TLI, sharply into the spotlight, for the over-arching objective of this project is to improve legume productivity in environments considered marginal for agriculture, due to heat and other stresses. Somehow, it seems that more of the world’s environment is becoming ‘stressed’ by the day, though luckily the giant beanstalk of our story is a hardy crop which can be grown on the poor soils and fragmented plots of these challenged lands.

So the legume of choice for this most uncommon road trip is the common bean, Phaseolus vulgaris L, and our Ethiopian bean breeding expert is Asrat Asfaw Amele of the Southern Agricultural Research Institute (SARI), who is the Lead Scientist of the TLI beans component in Ethiopia. Asrat is our friendly guide and fount of knowledge of all things Ethiopian throughout this impassioned passage into the ‘bean valley’, and we are accompanied by Bodo Raatz of the Centro Internacional de Agricultura Tropical (CIAT), recently appointed Principal Investigator of TLI’s bean research. At Areka research station we are joined on our journey by Daniel A Demissie, who, along the way, shares his many insights on beans, diseases such as bean stem maggot (BSM), and on drought . We are chaperoned throughout by our courageous driver, Mr Abebe, who at times resembles a pilot as we seem to fly over the bumpy terrain in the plucky pick-up that is our steed for the day.

Against the scenic backdrop of the Ethiopian landscape racing by, with background music courtesy of Teddy Afro (whose politically charged songs, sweet voice and infectious rhythm have made him nothing short of a legend in his homeland), I take advantage of this long and winding road trip to interview Asrat, where his answers echo the whirlwind tour rushing by outside – from a description of the landscape he knows so well, and toils in every day – to the impact that this project has had on national scientists, the impacts on farmers’ lives, as well as impacts that are likely to come in the not-too-distant future.

We consider farmers our partners. We try to understand what farmers are looking for, what they like, and we try to include their interests in our breeding materials so that the breeding materials released by our institution start to get wider adoption.” – Asrat Asfaw Amele (pictured).

The rich Ethiopian landscape

Revolution, alliances & partnerships

Ethiopia’s rich history, as varied as its topographical landscape, has known its fair share of extreme rulers. Now it seems the new ‘regime’ calling the shots is climate change, whose ravaging effects are seen worldwide, and no less in the bean fields of Ethiopia. Asrat even pinpoints climate change as the greatest challenge for the next generation of bean researchers, saying, “The farmers’ growing environment may be modified or a new environment may be created. That could also be a challenge – a new pest population or new disease may come; so the challenge in the future may be to breed or develop varieties which adapt to the changing environment.”

Beans line up

The revolutionaries needed to overthrow this ‘tyrant’, it seems, are those of the ‘triple alliance’ partnership, comprising: Ethiopia’s national scientists, researchers from the international science community including CGIAR Centres, and farmers. Firstly, with this approach, the science sector can understand farmers’ needs, which also has a reciprocal effect, as Asrat explains, “We consider farmers our partners. We try to understand what farmers are looking for, what they like, and we try to include their interests in our breeding materials so that the breeding materials released by our institution start are widely adopted.” Secondly, national and international science systems come together to work for a common goal – in Asrat’s words: “Now we’ve got the knowledge and we can speak a common language with people from advanced laboratories. It’s also brought us closer to international institutes like CIAT and other CG Centres – we work together, so they understand our system better and we understand how they function.” He adds, “We are getting technical backstopping from CGIAR Centres, so as a national partner we are doing work, and they are supplying germplasm. That’s the partnership that will continue in the future.”

The weapon used by this ‘revolutionary army’ is GCP’s double-barrelled approach which combines both traditional and molecular breeding practices and is proving to be effective in developing new, more productive bean varieties to combat drought and disease. Specifically of the TLI project, Asrat says, “It lets us know about molecular breeding, so it’s exposed us to new developments in science, especially in the application of molecular techniques and plant breeding.”

The ‘monster’, climate change, rears its ugly head only to be shot down expertly by Asrat and the mighty beans as he reveals, “A lot of farmers are growing our varieties, and, because of changing weather or instability, many people are starting to grow beans; beans are now becoming a major crop, especially in our mandate area.”

Capacity building …
At this stage, the major impact of the TLI beans component in Ethiopia has been on capacity building – both in terms of human resources and physical infrastructure, as Asrat illustrates, “In our breeding programme, capacity building has been an important aspect: scientists in our national system are being exposed to new technology, information, and training; we also have a full irrigation system in about 10 hectares of land, which will revolutionise our work.”

Magical bean diversity

… and on to farmers
By building on lessons learnt throughout this project, current impacts for the national science system will be translated into ‘real impacts’ in farmers’ fields in the near future. Indeed, Asrat hopes his future work will involve “getting the material into the hands of farmers, to see some impact or change, and to modernise and speed up breeding processes using markers developed by this project.”

So the ‘magic beans’ of our story tell of a rich brew brimming with such potent ingredients as molecular breeding, capacity building, partnerships spanning continents and research systems, true teamwork with the farmers in the fields, and the drive to conquer the new challenge of a changing climate.

The impacts from the TLI project are the pot of gold at this rainbow’s end, showing that fairy tales do come true, where ‘magic beans’ put down roots and grow real shoots, and are not just ‘castles in the air’.

BREAK-TIME AND BRAKE-TIME from beans for a bit: Steve Beebe takes a pause to strike a pose in a bean field.

“These [molecular breeding] techniques, combined with conventional methods, shorten the time it takes to breed improved varieties  that simultaneoulsy combine several traits.

And this means that we also get them out to farmers more quickly compared to phenotypic selection alone.”
– Steve Beebe

THE NEAR-PERFECT FOOD: Common beans (Phaseolus vulgaris L) comprise the world’s most important food legume, feeding about 200 million people in sub-Saharan Africa alone. Their nutritional value is so high, they have been termed ‘a near-perfect food’. They are also easy to grow, adapting readily to different cropping systems and maturing quickly.

That said, this otherwise versatile, adaptable and dapper dicotyledon does have some inherent drawbacks and ailments that crop science seeks to cure….

Rains are rapidly retreating, and drought doggedly advancing
Despite the crop’s widespread cultivation in Africa, “yields are low, stagnating at between 20 and 30 percent of their potential,” remarks Steve Beebe, GCP’s Product Delivery Coordinator for beans, and a researcher at the International Center for Tropical Agriculture (CIAT, by its Spanish acronym).

“The main problem is drought, brought about by climate change,” he says. “And it’s spreading – it already affects 70 percent of Africa’s major bean-producing regions.”  Drought decimates bean harvests in most of Eastern Africa, but is particularly severe in the mid-altitudes of Ethiopia, Kenya, Tanzania, Malawi and Zimbabwe, as well as in southern Africa as a whole.

A myriad of forms and hues: bean diversity eloquently speaks for itself in this riot of colours.

Drought, doubt and duality − Diversity a double-edged sword
“Common beans can tolerate drought to some extent, using various mechanisms that differ from variety to variety,” explains Steve. But breeding for drought resistance is complicated by the thousands of bean varieties that are available. They differ considerably according to growth habit, seed colour, shape, size and cooking qualities, and cultivation characteristics.

“A variety might be fantastic in resisting drought,” says Steve, ‘but if its plant type demands extra work, the farmers won’t grow it,” he explains. “Likewise, if consumers don’t like the seed colour, or the beans take too long to cook, then they won’t buy.”

Molecular breeding deals a hand, waves a wand, and weaves a band
This is where molecular breeding techniques come in handy, deftly dealing with the complexities of breeding drought-resistant beans that also meet farmer and consumer preferences. No guesswork about it: molecular breeding rapidly and precisely gets to the heart of the matter, and helps weave all these different ‘strands’ together.

The bean research team has developed ‘genetic stocks’, or strains of beans that are crossed with the varieties favoured by farmers and consumers. The ‘crosses’ are made so that the gene or genes with the desired trait are incorporated into the preferred varieties.

The resulting new varieties are then evaluated for their performance in different environments throughout eastern and southern Africa, with particular focus on Ethiopia, Kenya, Malawi and Zimbabwe which are the target countries of the Tropical Legumes I (TLI) project.

Propping up the plant protein: a veritable tapestry of terraces of climbing beans.

GCP supported this foundation work to develop these molecular markers. This type of breeding – known in breeder parlance as marker-assisted selection (MAS) – was also successfully used to combine and aggregate resistance to drought; to pests such as bean stem maggot (BSM); and to diseases such as bean common mosaic necrosis potyvirus (BCNMV) and to bruchid or common bacterial blight (CBB). The resulting ‘combinations’ laden with all this good stuff were then bred into commercial-type bean lines.

“These techniques, combined with conventional methods, shorten the time it takes to breed improved varieties that simultaneoulsy combine several traits,” comments Steve. “This means that we also get them out to farmers more quickly compared to phenotypic selection alone.”

Informed by history and reality
Breeding new useful varieties is greatly aided by first understanding the crop’s genetic diversity, and by always staying connected with the reality on the ground: earlier foundation work facilitated by GCP surfaced the diversity in the bean varieties that farmers grow, and how that diversity could then be broadened with genes to resist drought, pests and disease.

What next?
Over the remaining two years of Phase II of the Tropical Legumes I (TLI) project, the bean team will use the genetic tools and breeding populations to incorporate drought tolerance into farmer- and market-preferred varieties. “Hence, productivity levels on smallholder farms are expected to increase significantly,” says Steve.

Partnerships
The work on beans is led by CIAT, working in partnership with Ethiopia’s South Agricultural Research Institute (SARI),  the Kenya Agricultural Research Institute (KARI),  Malawi’s Department of Agricultural Research and Technical Services (DARTS) and  Zimbabwe’s Crop Breeding Institute (CBI) of the Department of Research and Specialist Services (DR&SS).

Other close collaborators include the eastern, central and southern Africa regional bean research networks (ECABREN and SABRN, their acronyms) which are components of the Pan-African Bean Research Alliance (PABRA). Cornell University (USA) is also involved.

Getting to the core of a world-favourite dessert by unravelling banana’s origin and genealogy

GCP has enabled us to lay a credible foundation, which gave us a leg-up in the intense competition that typifies the genome sequencing arena” – Angélique D’Hont, CIRAD researcher

‘A’ is also for Angélique, as you will see once you read on…

An ‘A’ to our banana team for ushering in a new era in banana genetics. But let soup precede dessert, and don’t let this worry you: stay with us because we’re still very much on the topic and focused on bananas, which offer the whole range from soup and starters, to main course and dessert, plus everything else in between, being central for the food security of more than 400 million people in the tropics: around a third each is produced in Africa, Asia-Pacific and Latin America, and the Caribbean. About 87  percent of all the bananas produced worldwide are grown by small-scale farmers.

Moving back then to soup for starters, we’re serving up our own unique blend of alphanumeric banana ‘soup’, spiced with ABCs, a pinch of 123s, plus a dash of alpha and omega. Curious about the ABCs? Look no further:‘C’ for getting to the core of ‘B’ for bananas, and an ‘A’ score for our ace genomics team that did it.

Read how GCP seeded … and succeeded, in helping open a new era in banana genetics. An achievement by itself, and an important milestone on the road to unlocking genetic diversity for the resource-poor, which is GCP’s raison d’être.

So get your travelling gear please, for time travel with a ‘midspace checkpoint’ in Malaysia.

We start in 2004, when GCP commissioned a survey of diversity with microsatellites (or SSRs, simple sequence repeats) for all mandate food crops in the CGIAR crop research Centres. The objective of that study was to make new genetic diversity from genebank accessions available to breeders.

The endpoint is opening new research avenues to incorporate genes for disease resistance, with the added bonus of an article published in Nature online on July 11 2012, entitled The banana (Musa acuminata) genome and the evolution of monocotyledonous plants.

It may not be quite as easy as the ABC and 123 that The Jacksons promise in song, but we promise you that the science is just as exciting, with practical implications for breeding hardy disease-resistant bananas. Onwards then to the first leg of this three-step journey!

(Prefer a shorter version of this story in pictures? We’ve got it! Choose your medium between Flickr and Facebook)

1) Let’s go Greek: the alpha and omega of it

Rewinding to the beginning

The proof of the pudding is in the eating: we imagine that Jean Christophe Glaszmann just has to be saying “Yummy!” as he samples this banana.

Start point, 2004: “At that time, several research groups had developed SSR markers for bananas, but there was no coordination and only sketchy germplasm studies,” recalls Jean Christophe Glaszmann (pictured), then the leader of what was GCP’s Subprogramme 1 (SP1) on Genetic Diversity on a joint appointment with CIRAD. He stepped down as SP1 Leader in March 2010, and is currently the Director of a multi-institutional research unit Genetic improvement and adaptation of Mediterranean and tropical plants (AGAP, by its French acronym) at France’s Centre de ccoopération internationale en recherche agronomique pour le développement (CIRAD) in Montpellier.

Jean Christophe continues, “The reference studies had been conducted with RFLP* markers, a very useful tool but far too cumbersome for undertaking large surveys. We mobilised Bioversity International, CIRAD and the International Institute of Tropical Agriculture for the project. The process took time, but delivered critical products.[*RFLP stands for restriction fragmented length polymorphism]

Fastforward to 2012, and gets just a little geeky…

Eight years down the road in 2012, the list of achievements is impressive, as evidenced by a suite of published papers which provide the details of the analysis of SSR diversity and describe how the data enabled the researchers to unravel the origin and genealogy of the most important dessert bananas. The origin of the predominant variety – Cavendish – suggested by the markers, involves two rounds of spontaneous hybridisation between three markedly differentiated subspecies. This scheme has been marvellously corroborated by linguistic patterns found in banana variety names as revealed in a paper published in 2011 in the proceedings of USA’s National Academy of Sciences.

But what else happened in between the start- and end-point? We now get to the really ‘sweet’ part of this bonanza for banana breeding!

It is now possible to conduct research to identify and incorporate genes for disease resistance within fertile populations that are close to the early progenitors, and then inter-cross them to re-establish sterility and obtain vigorous, disease-resistant and seedless progenies.

 2) Of bits, bananas, breeding and breadcrumbs

Threading all these bits together for breeding better bananas is akin to following a trail of breadcrumbs, in which GCP played an important facilitating role: where in the germplasm to undertake genetic recombination is one key; and then, how to expedite incorporation of disease resistance and how to control sterility – so as to first suppress it, then re-establish it – is another set of keys that are necessary for proficient breeding.

Hei Leung in the lab at IRRI.

In 2005, Hei Leung (pictured), then Leader of GCP’s Subprogramme 2 on Comparative Genomics (until June 2007) on a dual appointment with the International Rice Research Institute (IRRI), recognised that with GCP’s main focus being drought tolerance in crops, Musa (the banana and plantain botanical genus) was somewhat on the fringe. However, it was still important that GCP support the emergence of banana genomics.

Hei is currently Programme Leader of Genetic Diversity and Gene Discovery at IRRI. He remembers, “We had a highly motivated group of researchers willing to devote their efforts to Musa. Nicolas Roux at Bioversity was a passionate advocate for the partnership. The GCP community could offer a framework for novel interactions among banana-related actors and players working on other crops, such as rice. The team led by Takuji Sasaki of Japan’s National Institute of Agrobiological Science, which had vast experience in rice genome sequencing, added the scientific power. So, living up to its name as a Challenge Programme, GCP decided to take the gamble on banana genomics and help it fly.”

Angélique D’Hont, CIRAD researcher and lead author of the article published in ‘Nature’.

Through several projects, GCP helped consolidate Musa genomic resources, contributed to the establishment of medium-throughput DArT markers as well as the construction of the first saturated genetic map. Additional contributions included the first round of sequencing of large chromosome segments (BAC clones) and its comparison with the rice sequence and a detailed analysis of resistance gene analogues. All these findings have now been published in peer-reviewed journals. And while publication takes time, it still remains a high-premium benchmark for quality and validation of results, and for efficient sharing of information. It reinforces the value of collaboration, builds capacity and gives visibility to all partners, thereby providing potential new avenues for funding.

Such was the case with bananas: using a collaborative partnership framework established with the Global Musa Genomics Consortium, animated by Nicolas Roux and now chaired by Chris Town, the community developed a case for sequencing the genome. With the mentorship of Francis Quétier, contacts were made with various major players in genomics, which in the end formalised a project between France’s CIRAD and CEA–Genoscope, funded by the Agence Nationale de la Recherche and led by Angélique D’Hont (pictured) and Patrick Wincker.

GCP contributed DArT analysis for anchoring the sequence to the genetic map. But, as stressed by Angélique, CIRAD researcher and lead author of the Nature paper: “Above all, GCP has enabled us to lay a credible foundation, which gave us a leg-up in the intense competition that typifies the genome sequencing arena. We were delighted that France rolled the dice in our favour by funding this work.”

3) Musa musings on the road to and from Malaysia checkpoint

Three years down the road, the team published a description of the genome of a wild banana from Malaysia.

Jean Christophe communes with a Musa plant, perhaps musing “What’s your family history and when will you be fully grown?”

Let’s drill down to some technical facts and figures here: the Musa genome has some 520 million nucleotides distributed across 11 chromosomes, revealing traces of past duplications and bearing some 36,000 genes. While most genes derived from duplication tend to lose their function, some develop novel functions that are essential for evolution; bananas seem to have an outstanding range of transcription factors that could be involved in fruit maturity.

And while the road ahead remains long, we now have a good understanding of banana’s genetic diversity, we have genomic templates for functional studies (a whole-gene repertoire) as well as for structural studies (the chromosome arrangement in one subspecies) aimed at unraveling the genomic translocations that could control sterility in the species complex.

It is now possible to conduct research to identify and incorporate genes for disease resistance within fertile populations that are close to the early progenitors, and then inter-cross them to re-establish sterility and obtain vigorous, disease-resistant and seedless progenies.

This is undoubtedly an inspiring challenge towards unlocking the genetic diversity in this crop, which is central to food security for more than 400 million people in the tropics.

Joko infront of his office at ICABIOGRAD’s Molecular Biology Division.

Indonesian upland rice growers can expect to receive improved varieties that thrive in phosphorus-poor soils within a few years, thanks to the hard work of their national breeding programmes.

Joko Prasetiyono is a proud Indonesian researcher who loves rice.

“I don’t know why. I just love researching ways to improve it so it grows and yields better. I also I love to eat it,” says Joko with a laugh.

Having worked as a molecular breeder, concentrating solely on rice for 17 years at the Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development (ICABIOGRAD), one would expect a different reaction. But Joko says he’s as interested in the little white grain as much as when he started as an undergraduate with ICABIOGRAD.

And why wouldn’t he be when he and his team are contributing to research that has just been published in Nature and is set to reduce fertiliser application and improve rice yields in Indonesia and the world over by 20 percent!

Improving Indonesian varieties, no genetic modification

Farmers often use phosphate fertilisers to aid in growing rice in these areas, but this option is often too expensive for Indonesian upland growers.

The project has found plants that have a Pup1 locus (a collection of genes), with the specific gene PSTOL1, are able to tolerate phosphorus-deficient conditions and produce better yields than those not suited for the conditions. An Indian rice variety, Kasalath, was one such.

“We are breeding rice varieties that we know have a Pup1 locus and subsequent PSTOL1 gene in them with Indonesian varieties that are suited to Indonesia’s growing systems,” explains Joko.   

Partnering with the International Rice Research Institute (IRRI), ICABIOGRAD and their partner the Indonesian Center for Rice Research (ICRR) have improved the phosphorus tolerance of Indonesian rice varieties Dodokan, Situ Bagendit and Batur.

“The new plants we are creating are not genetically modified; just bred using smarter breeding techniques,” says Joko. “The aim is to breed varieties identical to those that farmers already know and trust, except that they will have the PSTOL1 gene and an improved ability to take up soil phosphorus.”

Joko says that these varieties are currently being tested in field trials and it will take another 2–3 years before Indonesian farmers will have a variety that will yield as well if not better, needing 30–50 percent less fertiliser.

Evolving Indonesian plant research

GCP is as much about its people and partnerships as its research and products. ICABIOGRAD benefited from a GCP capacity-building grant in mid-2007 to enhance the institute’s capacity in phenotyping and molecular analysis. The grant covered, among other areas, intensive residential staff training at IRRI; PhD student support; infrastructure such as a moist room, temperature-controlled centrifuge apparatus, computers and appropriate specialised software; and  a blast innoculation room. These capacity-building activities were coordinated by Masdiar Bustamam who has since retired, but was then a Senior Scientist at ICABIOGARD.

But coming back to Joko and the PSTOL1 work, Joko started on this project in 2005 as a GCP-funded PhD student at Bogor Agriculture University, Indonesia. He is grateful to be part of a transnational project, which has offered him technical support that he would not otherwise have been able to receive through ICABIOGRAD alone.

Joko believes the experience of working with IRRI, as a joint partner on this project, will leave an important, and lasting, legacy for researchers at ICABIOGRAD and ICRR. The partnership has also challenged the two local institutes to broaden their horizons past their borders.

“IRRI is teaching us how to use marker-assisted selection and we [ICABIOGRAD and ICRR] are just as busy identifying phosphorus-deficient hotspots in upland areas, choosing the best Indonesian recipient rice varieties for the gene, conducting the breeding and phenotyping testing,” he clarifies.

Breeding for sustainability

The ultimate goal of this project is to help Indonesian growers use marginal land.

Over half the world rice lands are deficient of ‘plant-available’ phosphorus, and Indonesia is no different. Joko explains that while there is plenty of phosphorus in the soil, plants are not able to access it.

“Other minerals in the soil like aluminum, calcium and iron are bound to phosphorus, shielding it from plants roots so they can only absorb a fraction of it.”

In most countries, farmers apply phosphate fertilisers to their crops to combat this deficiency. For Joko this is not a sustainable approach for a lot of Indonesia’s farmers because the fertilisers are expensive and costs will continue to rise as phosphate supplies dwindle.

“Our approach is a lot more sustainable and cost-effective than applying fertiliser. We’ll breed these new plants for phosphorus-poor soils to produce more roots so they can find more phosphorus. The more phosphorus they find, the more of it they can absorb.”

Joko hopes these new plants will help farmers on marginal lands to obtain decent yields without having to spend money on expensive phosphate fertilisers.

“It’s great that our work has been recognised by Nature for publication, but what we really want is to help rice growers here in Indonesia and around the world.”

“It is very rare that scientists can take their projects wherever they go. I’ve been very lucky to be able to do this, and much of this has to do with the support I’ve received from GCP.” – Matthias Wissuwa

In the world of phosphorus, Matthias (pictured) is somewhat of a ‘rock star, not that he would admit to it. We don’t understand why not, since to borrow his words, the project he’s involved has becoming something of a ‘celebrity project’ in the scientific community.

For  a decade-and-a-half, he has searched tirelessly for a rice gene that could improve the crop’s yield in phosphorus-deficient soils –which make up half of the world’s soils. Last month, his transnational team published in Nature that their 15-year quest had ended, having finally found the elusive gene – Pup1.

We celebrate this happy ending, especially as we had the added pleasure of talking to Matthias recently: it was delightful in listening to the modest German recount the long journey which has taken him from his home town of Hamburg, to USA, Japan, The Philippines and back to Japan, all this while,  faithfully ‘carrying’ Pup1 with him as he switched employers. As you’ve seen, Japan scores a double strike, so our ‘rock star’ is also ‘big on Japan’! 

Talking to Matthias, we could sense the achievement was only just sinking in – that he and his team’s years of laboratory work was becoming a practical reality that will aid rice-growing farmers from Africa to Asia,  and hopefully other grain growers in years to come. Here’s what Matthias had to say…

You started this project back in 1997. Tell us how you became interested in phosphorus deficiency and rice.

After completing my PhD in the United States, I accepted a postdoc position in Tsukuba, Japan, with the National Institute of Agro-Environmental Sciences (NIAES). It was an easy decision because my wife is Japanese.

My postdoc host, Dr Ae was interested in phosphorus, particularly in legumes. I originally started work on tolerance to phosphorus deficiency in groundnuts, but soon changed to rice to take advantage of the molecular tools available for rice.

Tsukuba is a very new city. It’s called The Science City in Japan because the Japanese government built it to house all the national research institutes. This was great for me as I became interested in QTL mapping, which was pioneered by scientists in Tsukuba. I got talking to people in the rice research community in Tsukuba and was introduced to Dr Yano, who was developing mapping populations for rice at the National Institute of Agrobiological Sciences. He kindly gave me his populations and that’s how I started to map QTL for phosphorus-deficiency tolerance in rice.

Dr Ae was perplexed by my decision, believing that studying legumes was far more challenging than rice. He always told me: “Rice is boring. They just make long, fine roots to capture phosphorus.” That was 15 years ago and he turned out to be right. Long roots are the secret for phosphorus uptake in rice, particular in Kasalath and varieties like that.

Field trials for phosporus-efficient rice in The Philippines.

Did you share Dr Ae’s hypothesis that longer roots were the secret to some rice varieties being able to tolerate phosphorus-deficient soils?

For a long time, I was not sure if it was just long roots. It was a real chicken-and-egg scenario – does strong phosphorus uptake spur root growth, or the other way around?

As it turns out, it is the latter – plants growing longer roots help with the uptake of more phosphorus – and Pup1 is responsible for this.

We have now shifted our aim and are looking for varieties of rice tolerant to phosphorus-deficient soils that either:

  • release organic acids, phosphatases or some other compound that makes phosphorus more readily available for the plant to absorb, or
  • manipulate soil microorganisms to favour those that can aid in making phosphorus more soluble, or
  • very efficiently utilise phosphorus once it is taken up.

All three mechanisms are found in legumes, so there is reason to believe that they exist in rice and we are now working on finding them.

GCP has been interested in the project since 2004 as its outcome aligns with GCP’s goals to improve crop yields and security in developing countries… It has become something of a ‘celebrity project’ in the scientific community, attracting researchers to work on the project or collaborate with us.

In 2002 you left NIAES and accepted a position with the International Rice Research Institute (IRRI), and were encouraged to continue your work on Pup1. When you moved back to Tsukuba in 2005 to accept the position you currently hold with the Japan International Research Center for Agricultural Sciences (JIRCAS), you were again encouraged to continue your Pup1 project, collaborating with your successor at IRRI, Dr Sigrid Heuer. How important has it been to you and the project to have the support of your institutes?

It is very rare that scientists can take their projects wherever they go. I’ve been very lucky to be able to do this, and much of this has to do with the support I’ve received from GCP. They’ve been interested in the project since 2004 as its outcome aligns with GCP’s goals to improve crop yields and security in developing countries.

When I left IRRI, Sigrid was just starting and was more or less free to take on the project, so I asked her if she’d be interested in continuing my work with Pup1 at IRRI and collaborate with me in Japan. She was actually the perfect person for the project because her background in molecular biology complemented my background as a plant breeder.

Over the past seven years, we have worked together very well, and with the addition of Rico Gamuyao, a PhD student supervised by Sigrid, things have recently progressed quite quickly to the point that we were able to pinpoint Pup1.

So GCP has played a major role along your journey?

Yes, definitely. The support from GCP on the Pup1 project, now in its 8th year, was instrumental at getting this project to where it is.

Quite simply, the funding from GCP allowed us to hire Rico as well as Juan Pariasca-Tanaka, a project scientist with me at JIRCAS. Neither Sigrid nor myself had the time to do all the hands-on work so having both Rico and Juan has been hugely helpful.

How important has the collaboration between IRRI and JIRCAS been for the project?

Are they playing with mud? Not at all! Working. Matthias (L) and Rico (R) have zipped up their boots and gone back to their bee…er…. we mean, roots, mucking mud here as they do some fieldwork related to the search for PSTOL1.

Tremendously important. Sigrid’s group at IRRI is relatively small as is mine in Japan, so we rely on each other’s complementary expertise when working on complicated projects.

We have also been fortunate to have constant interest in the project from the scientific community. It has become something of a ‘celebrity project’, and as such, attracted researchers to work on the project or collaborate with us.

For example, we are working with two US groups at Cornell University and Penn State, that are also funded by GCP, trying to track down Pup1 in other crops and identifying genes that control root architecture, and how different architectures may affect P uptake.

These collaborations are really exciting, and make it possible to answer questions that we could not answer ourselves, or that we would have overlooked, were it not for the partnerships.

It really has been a team effort and we wouldn’t have got to where we are now without all the help of everyone involved

You’ve been described as the Godfather and Guru of Pup1. How do compliments like this make you feel?

It makes me laugh but of course it’s a very well-meant comment, and to some extent, considering I’ve worked on it for 15 years, you could say that there is some truth to it.

I’ve done all the original work, but Sigrid has been just as instrumental. She did the part where my expertise was no longer adequate – the molecular side, looking at genes and thinking about the function of a gene and testing for its function.

It really has been a team effort and we wouldn’t have got to where we are now without all the help of everyone involved, which also includes the support of Dr Yano over the years.

…phosphorus deficiency is a worldwide problem that has recently gained public attention because of how expensive phosphate fertilisers have become…Farmers are always interested in saving money and improving yields and we believe this discovery will help with both.

Have you been surprised by the attention this project has received?

As I said, the project has always been in the scientific spotlight because it was the first to map a major QTL for phosphorus uptake.

We knew from the Sub1 story – the submergence tolerance gene, which was published in Nature 4–5 years ago – that the media would probably be interested in this similar discovery. I’m still very surprised that this unsexy story has caused such interest.

You have to remember though, phosphorus deficiency is a worldwide problem that has recently gained public attention because of how expensive phosphate fertilisers have become. About four years ago, the price almost tripled and continues to stay high.

Farmers are always interested in saving money and improving yields and we believe this discovery will help with both.

Phosphorus deficiency is probably even more critical in Africa than it is in Asia… This means Pup1 may have its biggest impact in Africa.

How will the research continue?

Having focused so much on the basic research, we now want to turn our attention to the application. IRRI and JIRCAS will train national breeding programmes to use marker-assisted selection and help them breed their own rice varieties with Pup1.

Sigrid and IRRI are mainly working with Asian national breeding programmes and we at JIRCAS focus more on African programmes such as the Africa Rice Center. Phosphorus deficiency is probably even more critical in Africa than it is in Asia, as phosphate fertilisers aren’t used nearly as much as they are in Asia. This means Pup1 may have its biggest impact in Africa.

We are also looking for new sources of tolerance to phosphorus-deficiency. One very exciting project involves West African rice (Oryza glaberrima) the father of the Nerica ™ (New Rice for Africa) varieties.

So far, we have found that this rice is very tolerant to phosphorus-deficient soils. It does have Pup1, but in addition harbours novel genes that also enhance performance on phosphorus-deficient soils.

We hope to discover a Pup2 in the years to come.

Preparing rice root samples (Photo: IRRI)ALL IN THE ROOTS: A plant’s roots are a marvellously multitalented organ. They act as fingers and mouths helping plants forage and absorb water and nutrients. They act like arms and legs offering a sturdy base of support so a plant doesn’t keel over. They help store food and water, like our stomach and fat cells. And in some plants, can spawn new life – we leave that to your imagination!

That is why it is of little surprise that this multitalented organ was the key to discovering why some rice lines yield better in phosphorus-poor soils, a puzzle whose answer has eluded farmers and researchers… until now.  And even better, the findings hold promise for sorghum, maize and wheat too. Please read on!

 In search of the key – The Gene Trackers
In 1999, Dr Matthias Wissuwa, now with the Japan International Research Centre for Agricultural Sciences (JIRCAS), deduced that Kasalath, a northern Indian rice variety, contained one or more genes that allowed it to grow successfully in low-phosphorus conditions.

For years, Matthias made it his mission to find these genes, only to find it was as easy as finding a needle in a genetic haystack. He teamed up with the International Rice Research Institute (IRRI), and with GCP’s support, the gene trackers were able to narrow the search down to five genes of interest.

“We had started with 68 genes and within three years, we had narrowed in on these five candidate genes. And then, one-by-one, we checked whether they were related to phosphorous uptake,” recollects Dr Sigrid Heuer, senior scientist at IRRI and leader of the team that published the discovery in Nature in August 2012.

Sigrid Heuer at a rice phosphorus uptake demonstration field in The Philippines.

“In the end we found that if a certain protein kinase gene was turned on in tolerant plants like Kasalath, then those plants would perform better in phosphorus-deficient soils.”

They named this protein kinase gene PSTOL1, which stands for Phosphorus Starvation Tolerance. “When we put this gene into intolerant rice varieties that did not have this gene, they performed better in phosphorus-deficient soils.”

The importance of phosphorus
Rice, like all plants, needs phosphorus to survive and thrive. It’s a key element in plant metabolism, root growth, maturity and yield. Plants deficient in phosphorus are often stunted.

Sigrid explains that whereas phosphorus is abundant in most soils, it is however not always easily accessible by plants. “Many soil types bond tightly to phosphorus, surrendering only a tiny amount to plant roots. This is why more than half of the world’s rice lands are phosphorus-deficient.”

Farmers can get around this by applying phosphate fertilisers. However this is a very expensive exercise and is not an option for the majority of the world’s rice growers, especially the poorer ones –the price of rock phosphate has more than doubled since 2007. The practice is also not sustainable since it is a finite resource.

By selecting for rice varieties with PSTOL1, growers will be less reliant on phosphate fertilisers.

How it works: unravelling PSTOL1 mechanics
In phosphorus-poor soils, PSTOL1 switches on during the early stage of root development. The gene tells the plant to grow larger longer roots, which are able to forage through more soil to absorb and store more nutrients.

“By having a larger root surface area, plants can explore a greater area in the soil and find more phosphorus than usual,” says Sigrid. “It’s like having a larger sponge to absorb more water.”

A rice variety — IR-74 — with Pup1 (left) and without Pup1 (right).

Although the researchers focussed on this one key nutrient, they found the extra root growth helped with other vital elements like nitrogen and potassium.

Another by-chance discovery was that phosphorus uptake 1 (Pup1), the collection of genes (locus) where PSTOL1 is found, is present within a large group of rice varieties.

“We found that in upland rice varieties – those bred for drought-prone environments – most have Pup1,” says Sigrid. “So the breeders in these regions have, without knowing it, been selecting for phosphorus tolerance.”

“When thinking about it, it makes sense as phosphorus is very immobile in dry soils, therefore these plants would have had to adapt to grow longer roots to reach water deeper in the soil and this, at the same time, helps to access more reservoirs of phosphorous .”

Breeding for phosphorus tolerance, and going beyond rice
Using conventional breeding methods, Sigrid says that her team introduced PSTOL1 into two irrigated rice varieties and three Indonesian upland varieties, and found that this increased yields by up to 20 percent.

“In our pot experiments,” she added, “when we use soil that is really low in phosphorus, we see yield increases of 60 percent and more. This will mean growers of upland rice varieties will probably benefit the most from these new lines, which is pleasing given they are among the poorest rice growers in the world.”

Sigrid also sheds light on broadening the research to other crop varieties: “The project team is currently looking at Pup1 in sorghum and maize and we are just about to start on wheat.”

Building capacity and ensuring impact
Like all GCP projects, this one invests as much time in building capacity for country breeding programmes as on research.

Sigrid and her team are currently conducting the first Pup1 workshop to train researchers from Bangladesh, India, Indonesia, Nepal, Philippines, Thailand and Vietnam. They will share molecular markers that indicate the presence of PSTOL1, techniques to select for the gene, as well as for new phosphorus-efficient varieties.

Breeding for phosphorus-efficient rice in the Philippines.

“The aim of these workshops is to take these important tools to where they are most needed and allow them to evolve according to the needs and requirements of each country,” says Dr Rajeev Varshney, GCP’s Comparative and Applied Genomics Leader. “Breeders will be able to breed new rice varieties faster and more easily, and with 100 percent certainty that their rice plants will have the gene. Within three to five years, each country will be able to breed varieties identical to those that growers know and trust except that they will now have the Pup1 gene and an improved ability to unlock and take up soil phosphorus.”

Joining hands in collaboration
This IRRI-led project was conducted in collaboration with JIRCAS and the Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development (ICABIOGRAD) working with the Indonesian Centre for Rice Research. Other partners included: Italy’s University of Milano, Germany’s Max Planck Institute in Golm, the University of The Philippines at Los Baños, USA’s Cornell University and University of California (Davis and Riverside), Brazil’s EMBRAPA, Africa Rice Center, Iran’s Agricultural Biotechnology Research Institute, Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and University of Dhaka in Bangladesh.

The GCP community, its labours and joys

If tools and resources are not put to use, then we labour in vain...GCP contributes to food security by providing breeders with integrated tools, techniques and services to speed up the selection cycle, be this by conventional or molecular breeding. GCP focuses on developing new materials and new techniques and delivering these, and the appropriate breeding tools, technologies and services, to breeders. I think GCP has been one of the most successful builders of research and development partnerships.

The Board’s focus is now on auditing the Programme, and mapping a strategy to sustain its successful partnerships and systems, so that these can continue to deliver products and capacity to the developing world.”

Seatbelts on please! Time to take a tour with Andrew, for an ‘aerial’ view of GCP from the very  ‘top’.

Please meet Andrew Bennett (pictured), the Chair of GCP’s Executive Board. Among other responsibilities, he is also President of the Tropical Agricultural Association, UK, chairs the SciDev.Net Board, and previously chaired the CIFOR Board. He was formerly Executive Director of the Syngenta Foundation and Director of Rural Livelihoods and Environment at the Department for International Development (DFID, UK) where he was responsible for professional advice on policy and programmes on livelihoods, natural resources, environment, sustainable development and research. Andrew has worked on development programmes in Africa, Asia, Latin America, the Pacific and the Caribbean.

Today, Andrew shares his perspectives on GCP’s work, its impact, the challenges, the community GCP has built, and the role of the Board. Please read on…

When was the GCP Board established, and what is its profile and role?
The Board was set up in mid-2008 towards the end of the first phase of the Programme. A review recommended that there be a fully independent Board, comprising people who had no conflict of interest with the Programme to facilitate decision-making.

Board members have between them a wide variety of skills and backgrounds, ranging from expertise in molecular biology to development assistance, socioeconomics, academia, finance, governance and change management.

We are committed to the role that can be played by science in development, and to the Programme. We have offered advice and helped the Programme’s Consortium Committee and management refocus the Programme. By all accounts, they seem happy with how things have evolved.

Because GCP is hosted by CIMMYT, the Board does not have to deal with any policy issues. That is the responsibility of the Consortium Committee. Our role is more to provide advice and to help with decision-making and implementation, which is great as we’ve been able to focus on the Programme’s science and people.

How long have you been involved with GCP?
Since the Board was established in 2008.

What does the GCP tagline – ‘Partnerships in modern crop breeding for food security’ – mean for you?
It means that all our undertakings are geared towards producing crop varieties that are tolerant to a range of environments, as well as being socially acceptable and appealing to farmers and markets.

How do you upgrade the planting material farmers have by fortifying it to combat the biotic and abiotic stresses? Half the challenge is breeding and selecting good material, and the other half is ensuring delivery of tools to breeders and new planting materials to farmers.

So GCP focuses on developing new materials and new techniques and delivering these, and the appropriate breeding tools, technologies and services, to breeders.

Why is GCP’s work important, and what does it mean for food security?
People who are food-secure have access to adequate food at all times to maintain healthy active lives. There are two sides to making this happen – access and availability.

GCP is increasing the number of varieties and lines tolerant to the conditions farmers are facing. What we cannot do is put money in the hands of poor people. If we supply people with the means to produce sustainable and healthy crops, they will have the means to produce food for themselves, and a means of making an income.

GCP contributes to food security by providing breeders with integrated tools, techniques and services to speed up the selection cycle, be this by conventional or molecular breeding.

For you, what have been the major outcomes of GCP so far?
GCP has shown that it is possible to form very productive partnerships across CGIAR institutes and advanced research establishments and those countries that have less scientific capacity. I think it has been one of the most successful builders of research and development partnerships. GCP has also shown public researchers can work very well with the private sector. The public sector has the means to build a lot of capacity.

I think GCP has demonstrated that it is possible to establish molecular breeding programmes in those parts of the world that do not have well-developed scientific infrastructure.

Just a little bit of money – relatively speaking of course – clear vision, and good leadership, can go very far, and produce tremendous benefits and progress.

GCP has also identified the constraints that we have to work within – the challenge of phenotyping and restrictions on the movement of genetic material to other parts of the world. GCP has paid particular attention to intellectual property [IP] because the information and materials GCP produces must remain in the public domain. IP in the international arena within which the Programme operates must span potentially conflicting national legislation regimes. It is a very complex area.

‘Challenge’ is in GCP’s name. What are the major challenges that the Programme has so far overcome?
Quite a number and more could be on the horizon. GCP has overcome some of these challenges. They include the problem of poor-quality phenotyping. This has been addressed through a comprehensive capacity-building programme, including laboratory and field infrastructure, and the training of research support staff in the developing-country field sites where GCP projects are being implemented.

Another challenge was focusing the Programme. At the start, the Programme was spread too thin, spanning too many crops and partners, but these have been progressively narrowed down in Phase II.

This narrowing is no mean feat in the public sector. In the private sector, you start with, say, a hundred projects, then after six months you halve them. After a year, you are down to 10 projects and you put all your resources into making those 10 ‘winners’ work. In the public sector, you keep the entire hundred going for three years, then you look for funding to keep them all running for another cycle. It’s a different culture: the private sector is product-oriented, while some aspects of the public sector emphasise contributing to the growth of knowledge and information, and to building or maintaining relationships, without necessarily asking about their usefulness and benefits to society.

The Board’s focus is now on auditing the Programme and mapping a strategy to sustain its successful partnerships and systems, so that these can continue to deliver products and capacity to the developing world.”

What are the future challenges that the Programme must overcome to remain sustainable?
There are many GCP activities that can be integrated into the new CGIAR Research Programmes. However, there may be other activities such as capacity building and IP management which – at this point in time – appear somewhat less easy to integrate into the new CGIAR Research Programmes.

There is also a danger – not unique to GCP but with all aid-assisted programmes – that when the money ends, everything will disappear into the archives. We have to make sure that doesn’t happen in this instance.

The Board’s focus is now on auditing the Programme and mapping a strategy to sustain its successful partnerships and systems, so that these can continue to deliver products and capacity to the developing world.

What are some of the lessons learnt so far?
GCP was born at a time when we thought molecular biology could solve all our problems quickly and efficiently. What I think we are finding is that molecular tools –while extremely useful – cannot entirely replace understanding the agronomy and phenotypic activities. Molecular biology alone is not a panacea or silver bullet for crop breeding; but it is a valuable tool.

Then there is capacity building: molecular breeding is a tool that you can only use if you have the capacity. Many parts of the world will require a lot of capacity building and support to be able to use the tools. GCP and its Integrated Breeding Platform can make a modest contribution to meeting this need through the proof-of-concept GCP Research Initiatives for selected crops and countries and establishing communities of practice.

If tools and resources are not put to use, then we labour in vain.

What has been the most enjoyable aspect of your position with GCP?
Without a doubt, attending the General Research Meetings has been the most enjoyable, meeting scientists from a wide range of institutes, backgrounds and countries.

These scientists come together because they share the same interests and a common goal. There’s a lively buzz of conversation. It is good to hear about what they are doing, what their aspirations are, and to learn from the knowledge and posters they bring to the meeting.

You don’t have to be a cutting-edge scientist to listen to these people whose enthusiasm is palpable. They are passionate, have a strong sense of community, enjoy what they are doing, and are just as keen to share this knowledge and enthusiasm. It’s all highly infectious!

A walk down memory lane with Masa

Photo: JIRCASWe caught up with Masaru Iwanaga (pictured right), previously Director General of CIMMYT  from 2002 to 2008, and now President of the Japan International Research Center for Agricultural Sciences (JIRCAS), based in Tsukuba, Japan. CIMMYT is GCP’s host Centre. Here’s what Masa had to say about GCP’s early years, and where the Programme is today…

What was the vision for GCP at its foundation?
Our vision for GCP was to unlock genetic diversity through the application of modern science.

In 2002, as CIMMYT’s Director General, I proposed GCP to CGIAR. I’m proud that I was successful in convincing CGIAR to add GCP to its suite of Challenge Programmes.

GCP was based on partnerships. Partnerships were key because we wanted to mobilise modern science, both inside and outside CGIAR. We wanted to utilise modern science and CGIAR genetic resources for crop improvement.

Dave Hoisington and Peter Ninnes helped me draft the concept framework for how GCP would work.

GCP’s tagline – ‘Partnerships in modern crop breeding for food security’ – what does this mean for you?
I think we wanted to take advantage of our progress, especially in genomics to utilise genetic resources for the betterment of rural livelihoods. We wanted to utilise partnerships to enhance the gains made. I was involved in the establishment of GCP, overseeing the appointments of previous and current Directors, Bob Zeigler and Jean-Marcel Ribaut. GCP has made outstanding progress since its founding.

Practically all CGIAR activities are based on partnerships. Historically, CGIAR had been viewed in some quarters as technology-supply-driven – that technology was pushed on farmers who had to adapt to new varieties and adopt the technology that accompanied it. In the early years, GCP was viewed in the same light. I wanted to correct that view. Our objective was the effective utilisation of the genetic diversity that CGIAR is conserving –utilising this diversity for crop improvement. I had to work very hard to make people see this.

From what I’ve heard and been involved in, GCP has been one of the more successful Challenge Programmes in terms of meeting expectations. My view is very positive.

I left CIMMYT four years ago, and the progress that GCP has made during this time has astounded me.

For me, my life back then seems so distant to where I am now. But, recently I visited a national programme in a developing country, and the people I met had a positive view of GCP, saying it added value to their programme.

I’m currently head of the Japan International Research Center for Agricultural Sciences [JIRCAS, Tsukuba, Japan]. We conduct technical research activities.

I have mentioned partnership several times. This is because GCP is a partnership involving many organisations for the purpose of enhancing the capacity of national programmes to utilise advanced technology for crop improvement, taking advantage of genetic diversity.

Germplasm conservation by CGIAR Centres can be centralised but crop improvement needs to be decentralised because it is, of course, influenced by the local environment. It means we need to have capable crop breeders in national programmes. However, national programmes have been weakened in many developing countries, for various reasons.

By building capacity for developing-country breeders, we can contribute to stability by offering them the necessary resources, services and tools to progress and advance their work, and make them more efficient – and therefore more effective – in doing their work.

My fondest memory of my involvement with GCP was attending technical meetings and hearing the dialogue between a biotechnologist and a germplasm curator who were discussing how they could utilise each other’s strengths to conserve germplasm and enhance crop breeding.

What role did CIMMYT play then in supporting GCP?
In my role as Director of CIMMYT, I tried hard to make sure that CIMMYT was not misinterpreted as taking over GCP. Our role was to provide a management and administrative support framework for GCP to develop in its own way.

It’s been a real pleasure revisiting this chapter of my life.

A shared vision

What is GCP all about and why is its work important? Why was GCP created? Read recollections from key people involved in GCP’s conceptualisation, and find out how realisation of the shared vision continues today. Featuring candid conversations with Masa Iwanaga, former Director General, CIMMYT; Dave Hoisington, Consortium Committee Chair; Andrew Bennett, Executive Board member; and Jean-Marcel Ribaut, GCP Director.

When was the last time you went to your local shop to buy something only to be told they’ve run out of it? How did you react? Like most of us, did you question how they could have run out – after all, isn’t it their business to adequately supply the demand?

Most likely you just went to another store. But what if there wasn’t another store around that had your product, or worse, there was actually a national shortage of your product? This is the reality that faces not just those after the latest iPad, but billions of people who just want something, anything, to eat.

With less productive land on which to grow crops, a more variable climate and more extreme weather events, farmers across all continents are struggling to produce crops, let alone increase yields to meet an ever-growing demand.

This scenario has continually raised its ugly head over the last 200 years as the world’s population has grown exponentially and shifted to urban surroundings. If not for the Green Revolution, inspired by the late Norman Borlaug’s agricultural development research within the Office of Special Studies in Mexico (now the International Maize and Wheat Improvement Center, more commonly known as CIMMYT, its Spanish acronym), the world population would have already suffered losses into the billions.

Even so, food insecurity is still recognised as a global challenge by the UN’s Food and Agriculture Organization (FAO). While there is debate over the cause for such insecurity, the advances of agricultural technology born from a Mexican-flavoured research programme are once again coming to the fore to meet the challenge.

Genebanks are not limited to conservation but are also a source of new alleles for crop improvement.

The genies in the genebank
Seedbank collections serve as insurance against unanticipated future threats to food security, the degradation of our environment and the loss of plant biodiversity.

But that is not all: the banks are not limited to conservation but are also a source of new alleles for crop improvement. The temperature-controlled CGIAR genebanks are a veritable treasure trove for plant breeding. Over the past four decades, their curators have scoured the planet, collecting, categorising and conserving more than 650,000 samples of crop, forage and agroforestry genetic resources, held in trust on behalf of humanity.

One such temperature-controlled genebank is located just outside the sweltering Mexico City: the CIMMYT genebank holds more than 150,000 unique samples of wheat and its relatives from more than 100 countries – said to be the largest collection of a single crop.

While genebank ‘stocks’ have always been open to plant breeders, it wasn’t until 2002 that CGIAR researchers embarked on a more structured and systematic approach using modern technologies to tap their breeding potential, thereby elevating the genebanks beyond their traditional collection and conservation role. Prior to that, far-sighted individual pioneering researchers had been studying (termed ‘screening’ in breeder-speak) the stocks for solutions to breeding problems and to improve crops, but the turning point for a concerted ‘institutional’ effort, would come in the early noughties.

By studying the genes of wild versions of, let’s say, wheat, researchers can find genes that could help cultivated wheat to better battle drought.

The dawn of a new generation
One of these researchers was Dave Hoisington (pictured), then with CIMMYT, and now Chair of GCP’s Consortium Committee, and ICRISAT’s Director of Research. Dave worked with the then newly appointed CIMMYT Director General, Masa Iwanaga, and helped draft a joint proposal with other institutes to CGIAR to form a Challenge Programme that could use the recent advances in molecular biology to harness their rich global stocks of crop genetic resources to create and provide a new generation of plants to meet farmers’ needs. This successfully gave rise to the CGIAR Generation Challenge Programme.

“GCP’s first task was to go in and identify the genetic wealth held within the CGIAR banks,” says Dave.

“To do this, we wanted to use the most recent molecular tools, like molecular markers, to help scan the genomes and discover genes in species related to crops of interest that could help increase yield.”

Let’s use an analogy from a familiar medium – text: think of this story you are now reading as the plant’s genome, its words as its genes and a molecular marker as a text highlighter. You can use different markers to highlight different keywords in this story. Once you can see these keywords, you can then study them in more detail, and, in the case of genes, see what they control in the plant, and how they affect its different aspects.

“At that time, we recognised that a Centre like CIMMYT could no longer undertake this tremendously complex task on its own,” recounts Masa (pictured).”We needed to work within a programme that could concentrate on the task and that rallied together various CGIAR Centres as well as research institutes outside CGIAR, especially in developing countries.”

Partnerships with spirit
Partnerships have always been a key ingredient to success. At the same time, they have led to the downfall of many projects.

Back in the early noughties, CGIAR recognised their business model and research system were not actively fostering partnerships between their different research Centres as much as they should have been, nor were they vigorously encouraging Centres to seek collaboration outside CGIAR.

This was one of the fundamental reasons for establishing the Challenge Programmes, says Jean-Marcel Ribaut (pictured), who, in his role as GCP Director, has been credited by the Board and Committee for the significant time he has taken to broker, nurture and manage GCP’s partnerships.

“One of our major outputs has been the human assets,” says Jean-Marcel with great pride. “We have created this amazing chain of people from the lab to the field.”

In fact, GCPs greatest asset – its ‘crown jewel’ – is its network of people and the capacity the Programme provides them with to buttress all the hard work, particularly in countries where the end products (crops) will be of most benefit.

…the GCP Spirit’ … is visible and palpable: you can recognise people working with us have a spirit that is typical of the Programme.”

“To make a difference in rural development, to truly contribute to improved food security through crop improvement and income for poor farmers, we knew we had to build capacity in these areas,” observes Jean-Marcel.

“I see our management style as fairly ‘paternal’, in the positive sense of wanting to see these groups of people succeed, and us helping them to do so. If a research site needs a pump for fieldwork, we work with a local or international consultant who will visit the partner and evaluate their needs, advise them on what type of pump they need, as well as other infrastructure they’ll need for the whole system to be sustainable. We’ll then provide training on how to use the pump most effectively. It’s an investment in the people as much as in the products they are working on because we are trying to change the system of how science within partnerships is conducted and supported, as much as we are trying tap genetic diversity and breed resilient crops for the developing world.”

We were attracted to GCP because of its strong facilitating role, which offered considerable support to addressing the bottlenecks associated with research programmes that researchers and CGIAR identified.”

This support and change have been major selling points for potential partners who have resonated with what Jean-Marcel calls ‘the GCP Spirit’ – partners open to sharing their skills, tools and knowledge, willing to sacrifice their views and leadership and, most importantly, support one another.

“It is visible and palpable: you can recognise people working with us have a spirit that is typical of the Programme,” says Jean-Marcel.

Funders like the Swiss Agency for Development and Cooperation (SDC) are attracted to, and impressed by, GCP’s approach as an honest and impartial ‘broker’.

“We were attracted to GCP because of its strong facilitating role, which offered considerable support to addressing the bottlenecks associated with research programmes that researchers and CGIAR identified,” says Carmen Thönnissen (pictured), Senior Advisor at SDC.

“GCP is also in line with SDC’s internal guidelines on Green Biotechnology, where it is our aim not to support single-donor initiatives but to work in larger programmes that have a clear focus on strengthening the national partner capacities too.”

At the beginning, most project leaders were from developed nations and CGIAR Centres. … now more than half of our projects are led by scientists in developing countries.”

A structured revolution within an evolution: aiming for products and sustainable change
GCP was designed in two phases over its 10-year life. The first was about the research and using genetic plant breeding techniques. The second and current phase focuses more on accessing modern breeding technologies and building capacity in developing countries to do the research for themselves.

Within nine years, GCP has produced useful tools and products from its studies of genetic resources.
These products have contributed to advancing knowledge, and will continue to do so into the future, particularly in plant breeding.

“At the very beginning, most project leaders were from established universities and institutes  in developed nations, and CGIAR Centres. However, over time there has been a major shift and now we are proud that more than half of our projects are led by scientists in developing countries,” says Jean-Marcel. “They’ve moved from the position of implementers to the role of leaders, while the CGIAR Centres and institutes in developed countries have evolved more into mentors and teachers. We hope this empowerment will allow national programmes to grow and establish themselves to be sustainable when the funding dries up.”

Challenges within the Challenge Programme
All this talk about spirit, collaboration and partnerships does make it sound as if GCP has found the winning formula, but Jean-Marcel is quick to counter such notions, and there have been constant course corrections in charting the Programme’s path. “If anything, our strength comes from recognising our weaknesses, acknowledging that we don’t have it all worked out, and embracing change where it is needed.”

A mid-term external review was conducted in 2008 to audit the Programme’s weaknesses, strengths and lessons learnt from both. This review resulted in some governance reforming, bringing about the Consortium Committee and an independent Executive Board.

“It’s a major improvement that we have an independent Board, allowing for focus, and without any conflict of interest. I think they are doing a great job,” says Jean-Marcel. “They are monitoring and evaluating what we are doing, providing plenty of feedback and ideas on how to move forward, and contributing a lot to the success of the Programme.”

The Board’s focus now turns to auditing the Programme and mapping a strategy to sustain its successful partnerships and systems, so they can continue to deliver products and capacity to the developing world.

Bird’s eye view from the Board
With more than 45 years of experience in international development and disaster management and, having worked in development programmes in Africa, Asia, Latin America, the Pacific and the Caribbean, Andrew Bennett (pictured) was a perfect candidate for the Board Chair.

“We are committed to the role that can be played by science in development, and to the Programme,” says Andrew. “We have offered advice and helped the Programme’s Consortium Committee and management refocus the Programme. By all accounts, they seem happy with how things have evolved.”

Advice and helping aren’t normally the words associated with how a Board works but, like so much of the GCP family, this isn’t a classical board.

Andrew explains “Because GCP is hosted by CIMMYT, the Board does not have to deal with any policy issues. That is the responsibility of the Consortium Committee. Our role is more to provide advice and to help with decision-making and implementation, which is great as we’ve been able to focus on the Programme’s science and people.”

That focus now turns to auditing the Programme and mapping a strategy to sustain its successful partnerships and systems, so they can continue to deliver products and capacity to the developing world.

Turning sunset to sunrise
With only two-and-a-half years left to run, Jean-Marcel and his team are working just as passionately on sustaining the partnerships, projects and outputs that GCP has created.

“We knew we weren’t going to be around forever, so we had a plan from early on to hand over the managerial reins to other institutes, including CGIAR,” says Jean-Marcel, with the slight affliction of a parent helping their child move out of home.

“We have begun integrating projects into the CGIAR Research Programmes (CRPs) which we hope will allow them to continue to grow and work effectively towards the goals set.”

At the same time, the Management Team, Committee and Board are all busy auditing the successes and failures of the Programme to quantify the achievements of what has been termed as one of the CGIAR’s more successful Challenge Programmes, and on how to make GCP products freely accessible to other research institutes and programmes.
