Scouring the planet for breeding solutions

Bindiganavile Vivek

Bindiganavile Vivek (pictured) is a maize breeder working at the International Maize and Wheat Improvement Center (CIMMYT), based in Hyderabad, India. For the past five years, Vivek and his team have been developing drought-tolerant germplasm for Asia using relatively new molecular-breeding approaches – marker-assisted recurrent selection (MARS), applied in a genomewide selection (GWS) mode. Their work in the Asian Maize Drought-Tolerance (AMDROUT) project is implemented through GCP’s Maize Research Initiative, with Vivek as the AMDROUT Principal Investigator.

Driven by consumer demand for drought-tolerant maize varieties in Asia, the AMDROUT research team has focussed on finding suitable drought-tolerant donors from Africa and Mexico. Most of these donors are white-seeded, yet in Asia, market and consumer preferences predominantly favour yellow-seeded maize. Moreover, maize varieties are very site-specific and this poses yet another challenge. Clearly, breeding is needed for any new target environments, all the while also with an eye on pronounced market and consumer preferences.

Stalked by drought, tough to catch, but still the next big thing

Around 80 per cent of the 19 million hectares of maize in South and Southeast Asia is grown under rainfed conditions, and is therefore susceptible to drought, when rains fail. Tackling drought can therefore provide excellent returns to rainfed maize research and development investments. As we shall see later, Vivek and his team have already made significant progress in developing drought-tolerant maize.

The stark reality of drought is illustrated in this warning sign on a desiccated drought-scorched landscape, showing the severity of drought in Asia

But they are after a tough target: drought tolerance is dodgy since it is a highly polygenic trait, making it difficult for plant scientists to pinpoint genes for the trait (see this video with an example from rice in Africa). In other words, to make a plant drought-tolerant, many genes have to be incorporated into a new variety. As one would expect, the degree of difficulty is directly proportional to the number of genes involved. In the private-sector seed industry, MARS  (PDF) has been successfully used in achieving rapid progress towards high grain yield under optimal growth conditions. Therefore, a similar approach could be used to speed up the process of introducing drought tolerance into Asian crops – the reason why the technique is now being used by this project.

AMDROUT Meeting Penang Dec2010_w

More than India: the AMDROUT project also comprises research teams in China, Indonesia, Thailand, The Philippines and Vietnam. In this photo taken during the December 2010 annual project meeting in Penang, Malaysia, the AMDROUT team assessed the progress made by each country team, and  team members were trained in data management and drought phenotyping. They also realised that there was a need for more training in genomic selection, and did something about it, as we shall see in the next photo. Pictured here, left to right: Luo Liming, Tan jing Li, Villamor Ladia, V Vengadessan, Muhammad Adnan, Le Quy Kha, Pichet Grudloyma, Vivek, IS Singh, Dan Jeffers (back), Eureka Ocampo (front), Amara Traisiri and Van Vuong.

The rise of maize: clear chicken-and-egg sequence…

Vivek says that the area used for growing maize in India has expanded rapidly in recent years. In some areas, maize is in fact displacing sorghum and rice. And the maize juggernaut rolls beyond India to South and Southeast Asia. In Vietnam, for example, the government is actively promoting the expansion of  maize acreage, again displacing rice. Other countries involved in the push for maize include China, Indonesia and The Philippines.

So what’s driving this shift in cropping to modern drought-tolerant maize? The curious answer to this question lies in food-chain dynamics. According to Vivek, the dramatic increase in demand for meat – particularly poultry – is the driver, with 70 percent of maize produced going to animal feed, and 70 percent of that going into the poultry sector alone.

GCP gave us a good start… the AMDROUT project laid the foundation for other CIMMYT projects”

 Show and tell: posting and sharing dividends

As GCP approaches its sunset in December 2014, Vivek reports that all the AMDROUT milestones have been achieved. Good progress has been made in developing early-generation yellow drought-tolerant inbred lines. The use of MARS by the team – something of a first in the public sector – has proved to be useful. In addition, regional scientists have benefitted from broad training from experts on breeding trial evaluation and genomic selection (photo-story on continuous capacity-building). “GCP gave us a good start. We now need to expand and build on this,” says Vivek.

AMDROUT trainees at Cambridge_w

AMDROUT calls in on Cambridge for capacity building. AMDROUT country partners were at Cambridge University, UK, in March 2013, for training in quantitative genetics, genomic selection and association mapping. This was a second training session for the team, the first having been September 2012 in India.

middle row: Ian Mackay (Cambridge), Muhammad Azrai, Le Quy Kha, Artemio Salazar;
back row: Roy Efendy, Alison Bentley (who helped organise, run and teach on the course, alongside Ian) and Suriphat Thaitad.AMDROUT country partners are from China’s Yunnan Academy of Agricultural Sciences (YAAS); the Indonesian Cereals Research Institute (ICERI); the Institute of Plant Breeding at the Unversity of Philppines at Los Baños (UPLB); Thailand’s Nakhon Sawan Field Crops Research Center (NSFCRC); Vietnam’s National Maize Research Institute (NMRI); and private-sector seed companies in India, such as Krishidhan Seeds.Curious on who proposed to whom for this AMDROUT–Cambridge get-together? We have the answer: a Cambridge callout announced the training, and AMDROUT answered by calling in, since course topics were directly relevant to AMDROUT’s research approach. 

 

 

According to Vivek, the AMDROUT project laid the foundation for other CIMMYT projects  such as the Affordable, Accessible, Asian (AAA) Drought-Tolerant Maize (popularly known as the ‘Triple-A project’) funded by the Syngenta Foundation for Sustainable Agriculture. This Triple-A project is building on the success of AMDROUT, developing yet more germplasm for drought tolerance, and going further down the road to develop hybrids.

 

Outputs from the AMDROUT project will be further refined, tested and deployed through other projects”

Increasing connections, and further into the future

Partly through GCP’s Integrated Breeding Platform (IBP), another area of success has been in informatics. Several systems such as the Integrated Breeding FieldBook, the database Maize Finder and the International Maize Information System (IMIS) now complement each other, and allow for an integrated data system.

There is now also an International Maize Consortium for Asia (IMIC–Asia), coordinated by CIMMYT, comprising a group of 30 commercial companies (ranging from small to large; local to transnational). Through this consortium, CIMMYT is developing maize hybrids for specific environmental conditions, including drought. IMIC–Asia will channel and deploy the germplasms produced by AMDROUT and other projects, with a view to assuring impact in farmers’ fields.

Overall, Vivek’s experience with GCP has been very positive, with the funding allowing him to focus on the agreed milestones, but with adaptations along the way when need arose: Vivek says that GCP was open and flexible regarding necessary mid-course corrections that the team needed to make in their research.

But what next with GCP coming to a close? Outputs from the AMDROUT project will be further refined, tested and deployed through other projects such as Triple A, thus assuring product  sustainability and delivery after GCP winds up.

As our Maize Research Initiative does not have a Product Delivery Coordinator, Vivek graciously stepped in to coordinate the maize research group at our General Research Meeting in 2013, for which we thank him yet again. Below are slides summing up the products from this research, and the status of the projects then.

Women in science

“Women can do advanced agricultural science, and do it well!” Elizabeth Parkes, cassava researcher, Ghana

Being a woman scientist in today’s world (or at any time in history!) is no mean feat, science traditionally having been the domain of men. We are therefore drawn to this sub-theme: Inspiring change, in addition to the global theme Equality for women is progress for all, To mark International Women’s Day tomorrow, UNESCO has developed an interactive tool which collates facts and figures from across the world on women in science. The cold scientific truth displayed in the attractive petri dish design shows that only 30 percent of researchers worldwide are women.

At GCP, we have been fortunate enough to have a cross-generational spectrum of, not only women scientists, but that even rarer species, women science leaders – who head a project or suite of projects and activities, and who actively nurture and mentor future science leaders – to ultimately contribute to the fulfilment of our mission: Using genetic diversity and advanced plant science to improve crops for greater food security in the developing world. The United Nations has designated 2014 as the Year of Family Farming. GCP’s women researchers have contributed to improving the lives of their farming counterparts the world over, especially in the developing world where on average, 43 percent of the agricultural labour force are women, rising to 60 percent and 70 percent in some regions. (FAO)

Please mind the gap…to leap to that all-important initiation into science

The UNESCO tool mentioned above and embedded to the left allows users to “explore and visualise gender gaps in the pipeline leading to a research career, from the decision to get a doctorate degree to the fields of science that women pursue and the sectors in which they work” with this affirmation: “Perhaps most importantly, the data tool shows just how important it is to encourage girls to pursue mathematics and science at a young age.”

In our International Women’s Day multimedia expo, we profile the life and work of a selection of our smart scientific sisters through words, pictures and sound, to explain just how they overcame obstacles, from taking that first hurdle to study science at an early age, to mobility up the research rungs to reach the very top of their game, all the while balancing work, life and family.

A blogpost fest to introduce our first special guests

Masdiar Bustamam

Masdiar Bustamam

We begin our show with a blogpost fest, and first up is GCP’s original Mother Nature, renowned scientist and constant gardener of the molecular breeding plot, Masdiar Bustamam. After a virtual world-tour of research institutes early on in her career, Masdiar took the knowledge of molecular breeding back home, to the Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development (ICABIOGRAD), where she personally took up the challenge to work with the fledgling world of biotechnology, set up a lab, and helped establish molecular breeding in her country. In an amazing 37-years-odd research career, Masdiar tended not only tender rice shoots, but also budding blossoms in the form of her many students, whom she nurtured and mentored throughout their studies, and who have now seamlessly inherited her mantle to carry on the mission with the same ever-bright spirit.

Rebecca Nelson

Rebecca Nelson

We now skip continents and oceans  to meet the feisty, continent- and crop-hopping scientist, Rebecca Nelson (Cornell University, USA). “I wanted to get out into the world and try and have a practical impact instead of doing research for the sake of research,” Rebecca says – and that she did, first leaving her native USA to work in the International Rice Research Institute (IRRI) in the Philippines. There she teamed up with friend and colleague, Masdiar Bustamam, to establish Masdiar’s laboratory at ICABIOGRAD, Indonesia. The American continent then called her back, where she moved countries and institutes, and switched from rice to maize research, marking the launch of her GCP experience – which simultaneously introduced her to her a whole new network of international crop researchers. This rich research tapestry was  woven together by a poignant pain deep in her heart, as a mother herself, of “so many mothers not being able to feed their families.” Rebecca wanted to combat this problem,  and crop science is her weapon.

Zeba Seraj

Zeba Seraj

Next, we meet another true mother of molecular plant breeding, Zeba Seraj (University of Dhaka, Bangladesh). Zeba, whose mind is perpetually on call in the pursuit of science, has been around the world, and from plants to animals and back again in the course of her multifaceted science career. During her PhD and postdoc experience in the UK, still with fauna, she cultivated her expertise in molecular biology and recombinant DNA technology, but a lack of opportunities in that field back in Bangladesh saw her enter the world of crop science, where she has remained ever since. Back at her alma mater, the University of Dhaka, she founded a molecular biology lab, and has nurtured and inspired generations of young biochemists. Her GCP project, using molecular markers to develop salt-tolerant rice, was a real eye-opener for her, and allowed her to truly ‘see’ how applied science and such a practical project would have a direct impact on her country’s food security, now and in the future. More

Sigrid Heuer

Sigrid Heuer

Our next scientist is also truly motivated by putting theory into practice through the application of upstream research all the way down the river, and directly into farmers’ fields. Sigrid Heuer (now with the Australian Centre for Plant Functional Genomics), a German national, has pursued her scientific ventures in Europe, Africa, Asia, and now Oceania, with many challenges along the way. Enter the Generation Challenge Programme, and the chance for Sigrid (then at IRRI)  to lead a major project, the Pup1 rice phosphorus uptake project, which taught Sigrid the A–Z of project management, and gave her ample scope for professional growth. Her team made a major scientific breakthrough, which was not only documented in international journals, but was also widely covered by global media.  From this pinnacle, Sigrid  passed on the baton to other scientists and moved on to new conquests. More

Arllet Portugal

Arllet Portugal

Now, all this research we’ve been celebrating generates a massive amount of data, as you can well imagine. What exactly can our scientists do with all that data, and how can they organise them? GCP’s Arllet Portugal, hailing from The Philippines, gives us the lowdown on smart and SHARP data management whilst also giving us some insights into how she started out on the long and winding road to leading data management for GCP’s Integrated Breeding Platform. In particular, Arllet describes the considerable challenge of changing researchers’ mindsets regarding the importance of effective data management in the context of their research, and enthuses over the excitement with which developing-country researchers welcome the GCP-funded electronic tablets they now use to collect and record data directly in the field. More

Armin Bhuiya

Armin Bhuiya

If there were a muse for young women scientists, it might very well be the subject of our next blogpost profile, Armin Bhuiya (Bangladesh Rice Research Institute). After completing her master’s degree on hybrid rice in her native Bangladesh, Armin was already thinking like a true change-catalyst scientist, trying to discover what line of research would be the most useful for her country and the world. After much deliberation, she embarked on a PhD focusing on developing salt- and submergence-tolerant rice. This wise choice would take her to study under the expert eye of Abdelbagi Ismail at IRRI, in The Philippines, with the helping hand of a GCP–DuPont postgraduate fellowship. There, she learnt much in the way of precise and meticulous research, while also taking advantage to self-train in modern molecular plant breeding methods. Our bright resourceful student has now advanced to the patient erudite teacher – as she takes home her knowledge of high-tech research methods to share with her colleagues and students in Bangladesh.

Elizabeth Parkes

Elizabeth Parkes

Hello Africa! Switching continents and media, we now we move from the written medium to tune in to the melodic tones of Elizabeth Parkes (Crops Research Institute [CRI] of Ghana’s Council for Scientific and Industrial Research [CSIR], currently on leave of absence at the International Institute of Tropical Agriculture [ IITA]). We’re now at profile number seven in GCP’s gallery of women in science. Elizabeth, who is GCP’s Lead Cassava Researcher in Ghana, narrates an all-inclusive engaging story on the importance to agriculture of women scientists, women farmers, and cassava the wonder crop – all captured on memorable sound waves in this podcast.

If the gravity of words inscribed holds more weight, you can also read in depth about Elizabeth in a blogpost on this outstanding sister of science. Witness the full radiance of Elizabeth’s work in the life-changing world in which she operates; as she characteristically says, “I’ve pushed to make people recognise that women can do advanced agricultural science, and do it well.” And she is no exception to her own rule, as she grew professionally, apparently keeping pace with some of the giant cassava she has helped to develop through the years. But it is her role as nurturer, mentor and teacher that really raises her head-and-shoulders above the rest, from setting up a pioneering biotech lab at CRI–CSIR to conscientiously mentoring her many students and charges in work as in life, because, for Elizabeth, capacity building and cassava are inextricably coupled!

Marie-Noëlle Ndjiondjop

Marie-Noëlle Ndjiondjop

In the wake of some recent high-profile screen awards, we close our multimedia expo with impressions of our science sisterhood through the medium of the seventh art: the magic visual world of the movies!  A good fit for a Friday!

The following tasteful and tasty (you’ll see why!) blogpost takes our film fans right onto the red carpet to rub shoulders with our scientific screen stars!

The first screen star you’ll meet is Marie-Noëlle Ndjiondjop (Africa Rice Center), Principal Investigator (PI) of GCP’s Rice Research Initiative, who opens the video-viewing session with seven succulent slices of rice research delight. Her movies are set in the rice-growing lands of Africa, where this savoury cereal is fast becoming a staple, and tackles the tricky topics of rice-growing constraints, capacity building, molecular breeding methods, and the colossal capacity of community in collaborative research projects.

Steaming rice bowl

Steaming rice bowl

What’s the latest from ‘GCP TV’? Plenty! With a world-favourite – rice – featuring high and hot on the menu.

Now serving our latest news, to tease your taste-buds with a tantalising and tingling potpourri of memorable cross-continental rice flavours, all captured on camera for our viewers…

Our brand-new series on YouTube serves up a healthy seven-course video feast inviting our viewers to sink their teeth into rice research at GCP.

First, we settle down for a tête-a-tête in the rice research kitchen with chef extraordinaire, Marie-Noëlle Ndjiondjop, Principal Investigator (PI) of GCP’s Rice Research Initiative in Africa, and Senior Molecular Scientist at Africa Rice Center. Target countries are Burkina Faso, Mali and Nigeria.

Marie-Noëlle Ndjiondjop

Starters, palate and pocket
Marie-Noëlle opens the feast with a short but succulent starter, as she explains succinctly in 30 seconds just how rice is becoming a staple in Africa. In the second course, Marie-Noëlle chews over the questions concerning combatting constraints and boosting capacity in rice research in Africa.

The third course is pleasing to the eye, the palate and the pocket! Marie-Noëlle truly sells us the benefits of molecular breeding, as she extolls the virtues of the “beauty of the marker”. Why should you use molecular tools? They’ll save you time and money!

Rice as beautiful as the markers Marie-Noëlle uses in molecular breeding

Wherefore art thou, capacity building in rice research in Africa?
The Shakespearean language alludes to the why of capacity building in Africa, as does video episode number four, which also tackles the what of this fourth dish in our banquet. Course number five offers the viewer a light look at how capacity building in Africa is carried out.

In the 6th course, Marie-Noëlle takes us out of this world and into MARS: she teaches us that ‘two are better than three’, as she explains how the novel bi-parental marker-assisted recurrent selection (MARS) method is proving effective when it comes to duelling with drought, the tricky three-headed monster comprising physiological, genetic and environmental components.

Blooming rice in the field

Of stars and scoundrels
The 7th and final course offers us a riveting tale of heroes and villains, that is, many heroes and a single villain! Our rice raconteuse, Marie-Noëlle, praises the power of the team, as a crew from cross-continental countries come together, carefully characterise their combatant (drought), before striking with environment-specific drought-tolerant varieties! AfricaRice’s project partners are Burkina Faso’s Institut de l’environnement et de recherches agricoles (INERA); Mali’s Institut d’économie rurale (IER); and Nigeria’s National Cereals Research Institute (NCRI). Collaborators are France’s Centre de coopération internationale en recherche agronomique (CIRAD); the International Center for Tropical Agriculture (CIAT); and the International Rice Research Institute (IRRI).

We hope these tasty teasers are enough to whet your appetite – you can savour each of the courses individually à la carte, or, for those with a daring desire to try the ‘all you can eat’ buffet for true rice gourmets, all seven courses are presented as a single serving on our YouTube channel.

Tastes from Asia
To further please your palate with our rice bowl of delights, our next stop is Asia. We are  pleased to offer you the Asian flavour through a peek into the world of molecular rice breeding in the Mekong region. Our connection to this project is through a GCP-funded capacity-building project entitled A Community of Practice for strengthening rice breeding programmes by using genotyping building strategy and improving phenotyping capacity for biotic and abiotic stresses in the Mekong region led by PI Jonaliza Lanceras-Siangliw, of the National Center for Genetic Engineering and Biotechnology (BIOTEC), Thailand (see project poster, and slides on a related drought-tolerance project led by Boonrat Jongdee). BIOTEC’s partners in the Mekong rice breeding CoP are the Cambodian Agricultural Research and Development Institute (CARDI); LAO PDR’s National Agricultural and Forestry Research Institute (NAFRI);  Myanmar’s Department of Agricultural Research (DAR); and Thailand’s Kasetsart University and Ubon Ratchathani University). The video also features former GCP PI, Theerayut Toojinda (BIOTEC) whose project was similarly entitled The ‘Community of Practices’ concept applied to rice production in the Mekong region: Quick conversion of popular rice varieties with emphasis on drought, salinity and grain quality improvement.
