Chickpeas on the map of champions in the genome world: Challenges, rewards… and ‘Rajeevs’

 Africa, Asia, Chickpeas, Genomics, Legumes  No Responses »
Jan 282013
 

Today, Nature Biotechnology published the first-ever draft genome sequence map for a chickpea variety (PDF). The map will help researchers and breeders the world over to – through molecular breeding methods – deliver to growers higher-yielding more resilient varieties of chickpeas. 

Now that we have the rewards in a nutshell, and we choose to chew the chestnut of challenges later in the story, let’s next decipher the ‘Rajeevs’ part in the title: introducing Rajeev K Varshney, our very own Leader of Comparative and Applied Genomics, who also led and coordinated the transnational collaboration that developed this map.

We had the pleasure of talking to the gently-spoken Indian, a week before the release of the paper, asking him to recount how the project began, and the challenges and success they faced along the way. We’ll soon get to what Rajeev had to say, but first, a rapid rewind for backgrounding before Rajeev tells us the rest of the story…

… we have the ‘borders’ done… a good idea of what the picture is, and where the rest of the pieces will fit.”

Reality check from the Genomics Gnome of Good News: two is but the twinkling of an eye…
The sequence map of the genotype CDC Frontier – a Canadian kabuli chickpea variety – took about two years to construct.”

No, the time taken is not the challenge since we’re yet to get to that part. In fact, in the world of genomics , two years is fairly fast, compared to, say, the time taken for sequencing other grain genomes such as maize, rice and wheat.

Rajeev attributes this to the interdisciplinary expertise of his team, most of whom are world leaders in their field, and to the enthusiasm and generosity of all partner institutes who funded the collaboration.

And with that background, on to our chat with Rajeev!

Sandwiches in the Sunshine State, and a search starts for the then unattainable holy grail

Q: Is it correct that this project started over sandwiches under a sunny sky in California?
Funnily enough, yes. We had the preliminary discussion during a lunchtime break at the fifth International Congress on Legume Genetics and Genomics back in July 2010. Doug Cook, from the University of California, Davis, and I, organised the meeting for select attendees to discuss the idea.

With daughter, Nanz. Rajeev in ‘Daddy-mode’, a galaxy away from genomic research.

Many researchers at the time had, or were toying with, sequencing parts of the chickpea genome to discover genes that helped plants tolerate salinity, drought, disease, and so on. The idea of mapping the whole genome, however, was thought to be unachievable given the cost and resources required. What Doug and I proposed to the 10-odd senior researchers that day was that we form an alliance to pool together our knowledge, funds and resources.

When we returned to our home institutes, we all approached our institutes or funding agencies in respective countries, to propose they consider funding the collaborative project. To be honest, this was probably the most challenging task of the project, as it often is with other projects, as they had a hard time recognising the benefits. However, we finally got there, and with the help of more than 20 institutes from North and Central America, Asia, Australia and Europe, we have successfully assembled 74 percent of the genome within two years.

Pieces fall into place for mix-and-match combinations

Now, you may say that 74 percent doesn’t equal the whole genome, but it does provide us with a map and pointers we’d never had before. Imagine doing a jigsaw without a picture to guide you – that’s how hard it was for us at the start. Now at least we have the ‘borders’ done, and we have a good idea of what the picture is, and where the rest of the pieces will fit.

Q:Why is mapping the chickpea genome so important?
Having the genome mapped is going to benefit all chickpea breeders, researchers and growers.

Say a conventional breeder wanted to create a new breed of chickpeas with drought tolerance. They would cross a domesticated, high-yielding variety of chickpeas, with a variety that tolerates dry conditions – most likely, lower-yielding – and then grow the progeny in the field. They wait for these progenies to grow, then visually select the best lines and make crosses with these. They keep doing this process over and over again for six to seven years until they’ve generated a new variety with the desired trait.

Different breed, mould and mode

Molecular breeders do it differently: instead of selecting the lines by visual inspection, they select lines based on their genes. This means they can correctly trace whether the progeny has received the genes which help the plant tolerate drought and only grow, test and cross with these plants, almost halving the time it would take through conventional methods.

With the map, researchers will be able to more rapidly identify genes of interest, and work with breeders to select for plants that display the favourable traits of these genes, whether this be for drought tolerance, pest resistance or for any other trait they are interested in.

Q: Good for researchers and breeders, but how is that going to benefit growers though?
Knowing which plant is more tolerant of drought from the start of the breeding process is going to significantly reduce the time it takes for breeders to develop these types of chickpea cultivars. So, growers will have new breeds of higher-yielding more resilient chickpeas available sooner.

Remember also that chickpeas are a very important crop for smallholders in the resource-poor harsh environments of sub-Saharan Africa, India and Southeast Asia. Not only do they grow it for food and to replenish soil nitrogen, they also export to India, the world’s largest consumer of chickpeas. Most of these farmers would be lucky to harvest one tonne per hectare, so any yield advantage means extra income.

This point is particularly relevant for GCP’s goal, which is to improve the livelihoods of such farmers.

Q: This was one of the largest collaborative projects you’ve coordinated in your relatively short career. What was the most challenging aspect?
Short answer is….many!  With it being a collaborative project, bringing together researchers from all around the world, it was always difficult to coordinate suitable times for Skype and phone meetings.

Personally though, my biggest challenge was trying to coordinate so many esteemed researchers. We all had great ideas and we all thought each of our ideas was the right one. I had to resolve all issues amicably and find a solution to move forward.

Luckily I have surrounded myself over the years with some good colleagues to whom I’ve always been able to turn to discuss any problems. Jean-Marcel Ribaut, who is the Director of GCP, was one particular colleague to whom I often turned to for advice, given his experience with coordinating all of GCP’s collaborative interdisciplinary projects. He also helped source much-needed funds and suggested several useful partnerships, which were vital in carrying out the project.

My boss at ICRISAT, William Dar, the Director General, has always been very supportive, and time and again went out of his way to make sure I had the funds, capacity and sanity to keep the project going! I am deeply indebted to him.

The future

Q: How will the research continue?
Researchers and breeders will be able to customise the genome map to fit their particular purposes. Most will be interested in using it to develop molecular markers, which breeders can use to highlight specific genes of interest for molecular breeding. As I mentioned earlier, this could realistically halve the time it takes to breed new varieties from six to10 years to four to five years.

One outcome of the project, which I’m particularly interested in exploring further, relates to chickpea diversity. When we compared the 90 chickpea genomes, we realised that that diversity in the elite varieties was very low, meaning they all had very similar alleles (form of genes).

This has come about because over the years, breeders and growers have continually chosen only a handful of chickpea varieties to continually breed with. This is because these breeds tend to produce higher yields, something which all growers want.

The drawback of this, however, is that if all the popular breeds are too similar, then they could all be susceptible to a particular disease. If this particular disease were to strike, then chickpeas could be wiped out – globally.

So this map will be a valuable tool to use to enhance genetic diversity in the elite gene pool, thus safeguarding the world’s supply of chickpeas.

Paradise left… then regained: A lifelong passion for plants, and plant science

Abdelbagi Ismail

 I was forever inquisitive as to how things grew, and questioning when they didn’t grow well. I think it’s what got me interested in plant science.”
– Abdelbagi Ismail, Plant Physiologist and Principal Scientist, International Rice Research Institute.

Today, we talk to Abdel. His riveting voyage in plant science starts on the bountiful banks of the Nile, before we sail on to Asia’s ricelands.  We’ll make a short stopover in USA for cowpeas and drought in between,  then proceed to to our main meal of rice, spiced and seasoned with a strong dash of salt-and-P.

It’s not just about food, but also family: you’ll  get to meet a sister Challenge Programme along the way. Intrigued? We hope so, so please do read on! 

‘A’ for Abdel and agriculture – an early passion for plants
From a tender age, Abdel was fascinated by agriculture.

Growing up on a small family farm backing onto the banks of the Nile in the Northern State of Sudan, he helped his parents in tilling the land, sowing and harvesting.

Abdel reminisces, “It was a relaxing paradise with all types of fruit growing around you year-round. Working and living on a farm, I was forever inquisitive as to how things grew, and questioning when they didn’t grow well. I think it’s what got me interested in plant science.”

Armed with a Bachelor’s and Master’s in Agricultural Sciences (agronomy, crop production, water relations) from the University of Khartoum, Sudan, Abdel moved to the University of California, Riverside, USA, for a PhD on drought tolerance in cowpeas.

“It was the first time I had ever left Africa, and it was a real eye-opener,” Abdel recalls. “It was a fantastic new page in my career too, as I was working with world-class professors and mentors. I chose to work on cowpeas because it is a hardy crop that can be grown in dry conditions which were – and still are – becoming more prevalent in sub-Saharan Africa.” (you can take a sidetrack here, to see our research on cowpeas)

 What interests me is how some societies have survived, and, in some cases, flourished because they invested in improving their plants and crops to adapt and adjust to weather adversities.”

Navigating away from the Nile, and discovering his niche
For this native son of the Nile, this move was a watershed. It marked the start of a dedicated – and still ongoing – career quest to understand how plants can adapt to better tolerate extreme environmental stresses such as higher and lower temperatures, too much or too little water, salinity, and nutrient imbalances.

“Abiotic stresses have had, and continue to have, a major impact on human life, with some societies disappearing altogether because of changes in soils or climate,” says Abdel. “What interests me is how some societies have survived, and, in some cases, flourished because they invested in improving their plants and crops to adapt and adjust to weather adversities.”

From time immemorial, the communities around the Nile where Abdel spent his childhood are a prime example of this flourishing against adversity.

IRRI beckons, and nurtures
In 2000, Abdel accepted a position at the International Rice Research Institute (IRRI) in The Philippines.

Abdel inspects cyclone-damaged rice in Isladi Village, southern Bangladesh.

“I saw it as an opportunity to convert knowledge and scientific discoveries into resources that could help needy farmers,” explains Abdel.

Abdel confesses that when he joined IRRI, his intention was to stay for a short stint and then move on. But as he became more involved in his work, he felt IRRI offered him the best opportunity to build his career, and to contribute to global food-security issues.

“I’ve been here for 12 years now. IRRI really is a great place to grow as a person and a researcher, and to learn how to become a leader.”

Having GCP provide ongoing funding and support for public institutions to conduct a long-term project has been pivotal to the success of the project. It has given us all the security we need to focus on conducting the complex research required…”

Trailblazing for GCP : a much-needed dash of ‘salt-and-P’
In 2004, Abdel proposed a collaborative project between nine different research organisations, across seven countries, to improve salt tolerance and phosphorus uptake efficiency in rice. The work was funded by a sister CGIAR Challenge Programme on Water and Food (CPWF).

This work caught – and held – GCP’s attention, because it sought to overcome a problem that negatively affects the lives of tens of thousands of rice growers around the world. The two resultant GCP-funded IRRI-led projects involved partners from Bangladesh, India, Indonesia, Vietnam and USA’s University of California, Davis. Globally, more than 15 million hectares of ricelands are saline, and more than one-third of all ricelands are phosphorus-deficient, hitting poor communities hardest.

In the nine years since, and together with his colleagues and partners, Abdel has developed the proposal into a productive and coherent suite of interconnected projects: he has managed and overseen most of the progress made during the discovery of the genes associated with salinity tolerance (Saltol) and phosphorus uptake (Pup1), and their insertion into well-known rice varieties that farmers in Bangladesh, Indonesia and The Philippines know and trust.

It’s all about rice: salt tolerance (Saltol) ‘meets’ phosphorus uptake (Pup1) in Bangladesh. Abdel is on the extreme right. Next to him is Sigrid Heuer, Principal Investigator of the ‘Pup1’ work.

Keeping the faith, and going where no rice has gone before…
A long-term horizon helps, since, just like art, science cannot be hurried: “Having GCP provide ongoing funding and support for public institutions to conduct a long-term project has been pivotal to the success of the project,” Abdel emphasises.

“It has given us all the security we need to focus on conducting the complex research required to advance our knowledge about these genes, then breed and develop popular varieties containing then. In some cases, we have developed lines with doubled yields, and grown rice in areas where it has never been grown before because the land was too saline.”

For Abdel, such achievements are heartening as they provide farmers with greater food and income security, which in turn improves their and their community’s livelihoods.

“It brings a smile to my face whenever I think about how our work helps to produce higher-yielding crops for poverty-stricken countries whose farmers often can only afford to grow one crop per year,” says Abdel sincerely.

Abdel continues to build upon, and has even employed, partners he has met through the GCP project…”We want to improve their capacity to take up new breeding techniques, such as the use of molecular markers, which can reduce the time it takes to breed new varieties from six to 10 years to two to three years…”

Continually building on the best
So what’s in store for the future?

Having discovered the Saltol gene and developed experimental lines, his team is now training breeders from country breeding programmes on how they can successfully breed for salt tolerance and tolerance of other abiotic stresses using their own popular varieties, thereby fortifying popular varieties with these much-needed tolerance traits.

“We want to improve their capacity to take up new breeding techniques, such as the use of molecular markers, which can reduce the time it takes to breed new varieties from six to 10 years to two to three years,” reveals Abdel. “This will allow them to breed for crops quicker, in response to ever-changing and extreme climate conditions.”

As for his other projects with IRRI, Abdel continues to build upon, and has even employed, partners he has met through the GCP project to help him with his Stress tolerant rice for Africa and South Asia (STRASA) project.

GCP helped IRRI attract support from other funders…”

Going further, faster, together… five and counting, still learning, and the future looks bright
STRASA is almost five years old and has another five years left to run.

“GCP helped IRRI to attract additional support from other funders, such as the Bill & Melinda Gates Foundation, to start STRASA, which seeks to support the development and distribution of stress-tolerant varieties in Africa and South Asia,” Abdel explains.

Abdel’s parting words? “I’m still committed to understand how plants can be manipulated to adapt to, and better tolerate, extreme environmental stresses, which seems  more feasible today than it has ever been before.”

Science in her blood – Born into botany, bloomed into biochemistry and molecular biology, and now in applied science

I’ve always enjoyed my job, particularly teaching students and young researchers, but this project has made me think about how I can do more practical science.” – Zeba Seraj, Biochemistry and Molecular Biology Professor, University of Dhaka, Bangladesh

Zeba Seraj

Growing up with a botanist as a father, Zeba Seraj was nurtured to look at plants in a scientific light. But at one stage in her life, she took a different fork on the road: she was more interested in rat livers and cow eyes, before becoming a ‘late bloomer’ in applied science and molecular plant breeding, which is her current niche.

Taking that fork: rats seduced, cows made eyes, but both lost…
Having completed her Undergraduate and Master’s in Biochemistry at the University of Dhaka, Bangladesh, during the 70s and 80s, she moved to Scotland for a PhD at the University of Glasgow. After being persuaded that molecular biology and recombinant DNA technology were not likely to be too different in animals and plants, she focused on the separation of nuclear proteins involved in post-transcriptional processing in the rat liver system.

“I then went on to work as a postdoc at the University of Liverpool, UK, for 18 months, where I worked on a bovine retina cDNA [complementary DNA] library,” Zeba recalls. “I was exposed to a number of recombinant DNA techniques and was pleasantly surprised to find DNA much easier to work with compared to proteins! I enjoyed it, but when I returned to the Bangladesh, there was no work in that field, so I turned to plants.”

The rise of rice, propelled by ‘Petrra’ project and petri dish
Back at her old University, one of Zeba’s first projects was working on salt tolerance in rice which allowed her to set up plant tissue culture facilities and establish a modest molecular biology laboratory. Zeba thereafter worked with the International Rice Research Institute (IRRI) and the Bangladesh Rice Research Institute (BRRI) on the Petrra project (poverty elimination through rice research assistance). The project was funded by the Department for International Development, UK. Meanwhile, she also spent a couple of months in the laboratory of the illustrious Dr John Bennett at IRRI, learning the latest technology in DNA markers and polymerase chain reaction (PCR) technology. This inital work would, in a way, lead her to GCP.

Meeting GCP, and banking on potential
Zeba joined the GCP community in 2005, working on the rice Saltol (salt tolerance) project. She was a focal collaborator in Bangladesh for this IRRI-led project that aimed to revitalise marginal ricelands by discovering and breeding into popular rice varieties ‘survival’ genes to enable rice to not only survive but also thrive on saline or phosphorus-poor soils.

“We were introduced to the project through the Principal Investigator, Abdel Ismail,” recalls Zeba. “Our lab was not very modern, but we did have all the facilities to do marker work, as well as a firm grasp on the theory, so IRRI and GCP must have seen potential in us.”

 …doing the research helped me understand the practical application better… It was a real eye-opener.”

Transiting from theory to practice
After 15 years of working as an associate professor and professor at the University of Dhaka (DU), mainly nurturing young biochemists, Zeba was re-energised by the thought of working on such a practical project that would have a direct impact on her country’s food security, and on its farmers’ livelihoods.

Nearly one million hectares along the Bangladesh coast are affected by varying degrees of salinity which has severely limited the introduction of modern high-yielding rice varieties, as few of these are saline-tolerant. Given Bangladesh’s high population, farmers need as bountiful yields as possible, and minimum risk of failure.

“After reading and teaching theory for so long, it was really exciting to actually put it into practice and work towards a practical outcome,” says Zeba.

“Actually doing the research helped me understand the practical application better too. It was a real eye-opener.”

 Using molecular markers allowed us to at least halve the time it would take to release stress-tolerant rice.” 

Gaining time: the ‘miracles’ and ‘magic’ of molecular makers
Zeba’s lab was responsible for the molecular evaluation and selection of rice lines bred by BRRI for insertion of the genomic region containing Saltol (discovered to confer salt toleranceby the previous IRRI-led GCP-funded project).

Md Sazzadur Rahman of BRRI assesses progress on a salt-tolerant rice variety in the field.

“We collected leaf samples from the BRRI-bred lines which were a combination of popular rice landraces and a Saltol donor.” explains Zeba ‘Landraces’ is ‘breeder-speak’ for varieties grown by, and popular with, farmers, but not necessarily improved by selective scientific breeding. Zeba continues, “We then used molecular markers which would indicate the presence of the Saltol genomic region.”

“The information we gathered guided the breeders at BRRI to select rice plants with the Saltol region. Selected plants were then further analysed with markers, to maximise the presence of popular alleles,” she adds. Allele is one of two, or more, forms of a gene – the alternative form of a gene responsible for a trait producing different effects.

“Using molecular markers allowed us to at least halve the time it would take to release stress-tolerant rice,” Zeba reveals.

 I will be the happiest person on earth the day they release the new lines, knowing that I’d helped to make a difference.”

Seven years on, what next?
Zeba is grateful that she and her lab were active partners in GCP projects for seven consecutive years: first in the IRRI-led project in 2005 to 2009, then in a follow-up supplementary capacity-building DU-led project from 2010 to 2011, for which Zeba was the Principal Investigator.

“I don’t think we could have done the work without the various GCP networks. Several times in the project we would lag behind and they’d offer us support to get us back on track,” says Zeba. “They also instilled in us the importance of proper data management, and we have now implemented their system to collect, store and report data for all of our projects. We also now have all the equipment and processes in place, meaning that we’re now able to accommodate similar projects, now and into the future.”

Personally Zeba feels the project has given her a new direction in her career that she’s keen to further explore. “I’ve always enjoyed my job, particularly teaching students and young researchers, but this project has made me think about how I can do more practical science,” confides Zeba.

As for the Saltol project, she is keeping a close eye on the application waiting for the news of high-yield salt-tolerant lines becoming accessible to all Bangladeshi rice farmers.

“I will be the happiest person on earth the day they release the new lines, knowing that I’d helped to make a difference.”

Born in Africa: A lifelong cross-continental love affair with science

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.”

Banana genetics: (not-so-)Easy as ♫ABC, 123♫

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.

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.

“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.

Chickpea research in Kenya – A boon for the fallow period

 Africa, Chickpeas, Crop breeding, Legumes  No Responses »
Jun 302012
 

“When we first started working on this project in mid-2007, our breeding programme was very weak,” says Paul Kimurto (pictured), Lead Scientist for chickpea research in the Tropical Legumes I (TLI) project, Kenya, and a lecturer in Crop Science at Egerton University.

“We have since accumulated a lot of germplasm, a chickpea reference set, and a mapping population, all of which have greatly boosted our breeding programme. From these, we have been able to select appropriate genotypes, and we obtained 400 breeding lines. None of this would have been directly possible without GCP’s support,” adds Paul. [Editor’s note: A ‘reference set’ is a sub-sample of existing germplasm collections that facilitates and enables access to existing crop diversity for desired traits, such as drought tolerance or resistance to disease or pests]

Due to their hardiness against drought, chickpeas have been steadily gaining popularity in Kenyan drylands – including the dry highlands – where they are grown as a ‘relay’ crop after wheat and maize harvests during the short rains, when the land would otherwise lie fallow. “Chickpeas have therefore increased food security and nutritional status of more than 27,000 households living in Baringo, Koibatek, Kerio Valley and Bomet Districts in Kenya, who frequently face hunger due to frequent crop failure of main staples such as maize and beans owing to climate change,” says Paul.

Chickpea adoption in these areas has increased due to close collaboration between GCP, ICRISAT and Egerton University through funding, training, resources and germplasm facilitated by GCP.

Exposure and capacity building
Through the project, various members of the Egerton research team have benefited from training in Europe, Africa and Asia on wide-ranging aspects of modern breeding, including data management. The learning resources that the team accesses through GCP are also shared widely and used as teaching materials and resources for faculty staff and postgraduate students not directly involved in the project.

“We have also benefitted from physical infrastructure such as a rain-shelter, irrigation system, laboratory equipment and a greenhouse. We didn’t have these, and probably couldn’t have had them, because all these are costly investments. This has greatly improved the efficiency of not only our research, but also our teaching,” says Paul. In addition, three postgraduate students are supported by GCP – two are pursuing PhDs and one a Masters, all using modern molecular breeding methods in their studies.

Community gains

Besides the university, capacity building has benefited the broader community: agricultural extension staff from the Ministry of Agriculture and from Koibatek Farmers Training Centre (one of the project’s research site), have been trained in various fields. The Centre manager attended a GCP course in Ghana tailored for research station staff (link below), as did an Egerton University technician.

In addition to aiding research trials, the irrigation system and weather station installed at Koibatek help with teaching and producing crop seed and planting materials as well as pasture for the community, since the Centre has a mandate to provide high-quality seed and livestock breeds to the community.

According to Beatrice Komen, a farmer in Koibatek, the irrigation system “has enabled the Agricultural Training Centre supply us with high-quality pasture and crop seeds for planting during the right time because Egerton University uses it to produce sufficient seed without having to rely on seasonal conditions.”

Paul adds, “The automated weather station is a first in the region.” The weather station also feeds regional data into the national meteorological database and is used for teaching by secondary schools in the community.

Going further, faster
Paul observes “With the direct funding we obtain through the project, we are able to expand into other areas of dryland research such as soil science and nitrogen fixation for chickpeas. Our efficiency has also increased: with the greenhouse and rainout shelter, we can now rapidly obtain generation crosses. And the irrigation system means we can now do off-season trials without having to wait for seasonal changes.”

“We have learnt a lot through our involvement with the Programme, including outsourcing of genotyping services which GCP fully supports, the advanced tools and wide range of services offered by the Integrated Breeding Platform for both breeding and data management,” says Paul. “We have also received digital tablet for electronic field data collection in a more efficient and accurate manner compared to the traditional pen and paper.”

The goal
“Our goal is to apply the modern breeding methods we have learnt to release new improved drought- and disease-resistant varieties before the project closes in mid-2014.” Some of these new methods include using quantitative trait loci (QTLs) through marker-assisted selection (MAS) and marker-assisted backcrossing (MABC).

“The results we obtain will provide foundation seed that can then be used for mass production through the Tropical Legumes II project,” says Paul.

“Our task is not complete until we have improved varieties in the hands of farmers,” he concludes.

Hitting the nail on the head: A nuts-and-bolts approach to local capacity empowerment (short version)

Breathing life into support services

By addressing the needs at the heart of quality agricultural research, right there on the station, GCP was the first to cotton on to a crucial missing link between researcher, research station, and support services.” – Hannibal Muhtar (pictured)

“One thing that really energises me,“ enthuses GCP Consultant Hannibal Muhtar, “is seeing people understand why they need to do the work, and being given the chance to do the how.”

And so was born another wonderfully fruitful GCP collaboration. Hannibal, who describes the assignment as “a breath of fresh air,” was asked to identify, together with GCP project Principal Investigators, African research sites of ongoing or potential GCP Research Initiative projects where effective scientific research might be hampered by significant gaps in one fundamental area: infrastructure, equipment and support services. As at June 2012, 19 sites had been selected.

Meet Hannibal Muhtar (audio clip)

Embarking on the voyage to change, storms ‘n’ all
In 2010 and 2011, Hannibal visited these stations, meeting staff at all levels and functions, for an in-depth analyses and appropriate recommendations to assure high-quality field evaluations for GCP-funded projects. With funding from GCP’s Integrated Breeding Platform (IBP), and with the openness, commitment and energy of station staff to implement these recommendations, the efforts are, starting to bear fruit.

Flashback to 2010. Photo 1: Hannibal (centre) at a planning session at Sega, Western Kenya, with Samuel Gudu of Moi University  (right) and Onkware Augustino (left). Photo 2: Similarly, at Tanzania’s Agricultural Research Institute, Naliendele, with Omari Mponda (right).

But it has not all been smooth sailing, and the storms encountered along en route should not be underestimated.

Weeds, wear and tear, and a walk on the wild side
“The real challenge,” says GCP’s Director of Research, Xavier Delannay (pictured), “is not in the science, but rather in the real nuts-and-bolts of getting the work done in local field conditions.” The obstacles, are often mundane – missing or faulty, weather stations or irrigation systems; weed-infested fields ravaged, or poor drainage, for example. Yet such factors compromise brilliant research. Take unfenced plots for example – equipment gets stolen, and animals roam freely.

Getting down to the brass tacks of local empowerment, and aiming higher
The overarching objective is, in Xavier’s words, “The effective running of local stations, for facilitating local research, improving local crops, and ultimately leading to empowerment and self-reliance of local farming communities.”

In tackling the matter, Hannibal employed a multi-faceted customised approach, based on the needs of each site, for both equipment and training for technicians, tractor operators and station managers. The dedication of the managers to both learn and continue these efforts after the training was particularly gratifying, since it assures sustainability.

“At the end of the day, it’s about achieving food security and improving livelihoods… which pave the way for healthy families and profitable agriculture,” concludes Hannibal.

Lights, curtain… action!
Much like in theatre, with all the ‘props’ in place, field trials are now performing well, thanks to streamlined ‘backstage’ support. Hannibal likens the positive feedback from the partners he has worked with to “A glass of cold water, after a long day in the sun!”

“With proper infrastructure in place, and with research station staff duly equipped with the hands-on expertise and practical know-how to utilise and apply this infrastructure and training, we’re now seeing field experiments being conducted as they should be, and getting good-quality phenotyping data as a result,” says Xavier. “Moreover,” he continues, “by providing glass-houses or the capacity to irrigate in the dry season, we are enabling breeders to accelerate their breeding cycles, so that they can work all year round, rather than having to wait until the rain comes.”
Examples include sites in Kenya, Mali and Nigeria.

The missing link
As the nuts-and-bolts begin to fall in place for, Hannibal reveals: “By addressing the needs at the heart of quality agricultural research, right there on the station, GCP was the first to cotton on to a crucial missing link between researcher, research station, and support services.”

…and yet another missing link…
But the job is not quite done. One crucial gap is the sensitisation of upper management – those at the helm of national research institutes and research station Directors – to support and sustain infrastructure, training and related services. In some cases, costs could be easily met by utilising a priceless asset that most institutes already have, and which they could put to greater us – land and a controlled environment.

Upper management needs to be actively on board. “A research institute should work like a good sewing machine,” says Hannibal. “All well-oiled, all parts working well, and everybody knowing what they need to do.”

In the meantime, however, results from the field suggest that researchers in GCP projects are already reaping the benefits from improved infrastructure and support services, and are already off to a good start.

The ‘stage’ is therefore set: ‘backstage’ and ‘props’ are well primed, performance trials are acting like they should, and the ‘theatre directors’ have an eye on sustainability after GCP’s final curtain call in 2014.

So, long may the show go on, with a cautionary word, however, to continually seek ways to not only maintain but also enhance performance!

Embarking on the voyage to change, storms ‘n’ all
Hannibal, armed with years of practical experience in the application of engineering sciences in agriculture and developing countries, as well as an attentive ear to the real needs of researchers, embarked on a series of visits to these research stations in 2010 and 2011, meeting with staff of all levels, departments and functions, carrying out in-depth analyses and draw up concrete recommendations for infrastructure and support service investments for each of the sites so that good-quality field evaluations (‘phenotyping’ in ‘breeder-speak) of GCP-funded projects could be conducted. Thanks to funding from GCP’s Integrated Breeding Platform (IBP), and to the openness, commitment and energy of research staff on the ground to implement these recommendations, the efforts of multiple cross-cutting partnerships across Sub-Saharan Africa are, in 2012, starting to bear fruit. But it has not all been smooth sailing, and the storms encountered along the way to reach this end goal should not be underestimated.

Weeds, wear and tear, and a walk on the wild side
The obstacles, says GCP’s Director of Research, Xavier Delannay (pictured, can often be mundane in nature – a  lack of or faulty weather stations or irrigation systems, or fields ravaged by weeds or drainage problems and in dire need of rehabilitation, for example. Yet such factors compromise brilliant research. A simple lack of fencing, Xavier and Hannibal expound, commonly results not only in equipment being stolen, but also in roaming cattle and wild animals – boars, monkeys, hippopotamus and hyena, to name but a few – stomping over precious experiment sites and posing serious threats to field staff safety. “The real challenge lies not in the science, but rather in the real nuts-and-bolts of getting the work done in local field conditions,” he explains.’’

Hannibal concurs: “If GCP had not invested in these research support infrastructure and services, then their investment in research would have been in vain. Tools and services must be in place as and when needed, and in good working order. Tractors must be able to plough when they should plough.’’

But a critical change is also needed in mindset and budgeting. ‘’The word ‘maintenance,’’’ a Senegalese partner commented to Hannibal, describing his institute, “does not exist in our vocabulary and is not a line-item on our budget.”

The problem then is not always about limited funds but rather much more on how the funds available are budgeted, excluding the all-essential support services.

Getting down to the brass tacks of local empowerment, and aiming higher
Multi-lingual and fluent in English, Arabic and French, Hannibal employed a multi-faceted customised approach, based on the needs of each site, be it sharing his tricks-of-the-trade and improvising local solutions, or guiding researchers in identifying their specific needs, as well as on where and how to request equipment, just to mention a few examples. In other cases he would teach local station managers to build and apply simple yet revolutionary tools such as land-levellers (referred to as ‘floats’ in industrial-speak), as well as row-markers for more uniform spacing between rows and plants in the field.

In addition, he would organise a training workshops in either English or French, with different content for technicians, machine operators and station managers. The dedication demonstrated by this latter group to both learn and continue these efforts after the training was particularly pertinent for ensuring the long-term sustainability of the investments.

A colourful menu of options, then, for achieving one common overarching objective, which, as summarised neatly by Xavier, is: “The effective running of local experiment stations, for facilitating local research, improving local crops, and ultimately leading to empowerment and self-reliance of local farming communities.”

“At the end of the day, it’s about achieving food security and improving livelihoods,” Hannibal emphasises. Looking back at some of the research stations that are now well-equipped and are being managed well, and the improved crop varieties being produced and projected, Hannibal highlights the “harmonious chain” triggered as a result: “Food security and better livelihoods pave way for healthy, well-fed families, and agriculture growing beyond subsistence into an economic activity,” Hannibal concludes.

Lights, curtain… ACTION!
Much like in theatre, with all the ‘props’ in place, Hannibal reports that field trials are now performing well, thanks to the all-important ‘backstage’ support service elements being in good shape. Hannibal likens the positive feedback from the partners he has worked with to “A glass of cold water, after a long day in the sun!”

And there’s a beautiful simplicity to the impacts described: “With proper infrastructure in place, and with research station staff duly equipped with the hands-on expertise and practical know-how to utilise and apply this infrastructure and training, we’re now seeing field experiments being conducted as they should be, and getting good-quality phenotyping data as a result,” says Xavier. “Moreover,” he continues, “by providing glass-houses or the capacity to irrigate in the dry season, we are enabling breeders to accelerate their breeding cycles, so that they can work all year round, rather than having to wait until the rain comes.” Sites hosting GCP projects on rice in Nigeria, as well as on sorghum and rice in Mali, are just a few examples of those enjoying off-season work thanks to new irrigation systems.

Similar good news is expected soon for cassava in Ghana and in northern Nigeria. And yet more good news: in some cases, the impacts have not been limited to the trials, or even to the research trials and stations alone, as Xavier highlights with an example from Kenya: “The establishment of an irrigation system on a plot at Koibatek Farmer Training Centre – a partner of Egerton University – yielded excellent results for chickpea experiments. We emphasised that we did not want the equipment to be ‘bracketed’ exclusively for science and experiments. So, it was also used to train staff and farmers from the local community as well. This was greatly appreciated.”

Seeing the nuts-and-bolts now firmly in place for the majority of the sites visited, Hannibal believes GCP has facilitated a pioneering approach to local capacity building: “By addressing the needs at the heart of quality agricultural research, right there on the station, GCP was the first to cotton on to a crucial missing link between researcher, research station, and support services,” he reveals.

…Another missing link…
But the job is not quite done. One crucial gap is the sensitisation of upper management – those at the helm of national research institutes and research station Directors – to support and sustain infrastructure, training and related services. In some cases, costs could be easily met by utilising a priceless asset that most institutes already have, and which they could put to greater us – land and a controlled environment.

Upper management needs to be actively on board. “A research institute should work like a good sewing machine,” says Hannibal. “All well-oiled, all parts working well, and everybody knowing what they need to do.”

In the meantime, however, results from the field suggest that researchers in GCP projects are already reaping the benefits from improved infrastructure and support services, and are already off to a good start.

The stage is therefore set: backstage and props are well primed, performance trials are acting like they should, and the ‘theatre directors’ have an eye on sustainability after GCP’s final curtain call in 2014.

So, long may the show go on, with a cautionary word, however, to continually seek ways to not only maintain but also enhance performance!

In Phase I (2004–2008), GCP’s focus was on exploration and discovery with an emphasis on crop diversity, while in Phase II (2009–2014), the emphasis is on application and impact, centering on breeding and services to breeders.

Phase I work covered 21 plants, while Phase II concentrates on improving nine key crops for drought tolerance :

  • beans
  • cassava
  • chickpeas
  • cowpeas
  • groundnuts
  • maize
  • rice
  • sorghum
  • wheat.
