Quick Summary

  • Consortium aims to improve Africa's traditional crops
  • Sequencing speeds breeding for more nutritious, productive crops
  • Improved crops could help eliminate malnutrition and stunted growth

澳门六合彩开奖结果走势图 is partnering in a global plant-breeding consortium that is fighting malnutrition and poverty in Africa by improving the traditional crops of the continent.

The African Orphan Crop Consortium 颅颅鈥 conceived by Howard Shapiro, a senior fellow at 澳门六合彩开奖结果走势图 and the chief agricultural officer at Mars, Incorporated 鈥 is making great strides in its ambitious attempt to map and make public the genomes of 101 indigenous African foods.

These 鈥渙rphan鈥 crops are crucial to African livelihood and nutrition, but have been mostly ignored by science and seed companies because they are not traded internationally like commodities such as rice, corn and wheat.

The genomic data on African orphan crops will help plant breeders more quickly select for traits that improve the nutritional content, productivity and resilience of Africa鈥檚 most important food crops.

The ultimate goal of the consortium is to eradicate stunting 鈥 a medical affliction resulting from chronic malnutrition that affects about 195 million children around the world. In some African countries, about 40 percent of the children under age 5 are stunted and never reach their full potential 鈥 physically, mentally or economically.

Uncommon collaboration 

Launched in 2012, the African Orphan Crop Consortium brings together Mars, 澳门六合彩开奖结果走势图, and a wide range of researchers, industry groups and policymakers. Together, collaborators have contributed about $40 million of in-kind support.

The World Agroforestry Centre built a state-of-the-art genomics laboratory in Nairobi, Kenya, and 澳门六合彩开奖结果走势图 expanded its intensive, hands-on Plant Breeding Academy into Africa. At the Plant Breeding Academy, Africa鈥檚 top breeders learn how to incorporate genomic information, statistics and the latest breeding strategies into their programs.

To improve a crop, breeders traditionally cross plants with desired traits and select the best offspring over multiple generations. Some traits, such as flavor and size, are often determined by many genes acting together, while other traits, like disease resistance, may be regulated by a single gene. Once a plant genome has been sequenced, breeders can home in on genes that affect specific traits and select for those genes at the seedling or seed stage. This accelerates the crop improvement process.

Helping children, families and farmers

鈥淚 believe this project will succeed where others have failed because it focuses on crops that have evolved to grow here,鈥 said Busiso Mavankeni, a plant breeder with Zimbabwe鈥檚 Department of Research & Specialist Services. 鈥淏y improving these neglected crops, we help the children who eat them and the farmers who depend on them to support their families.鈥

Mavankeni, who graduated from the Plant Breeding Academy in 2014, is working to improve Bambara groundnut, a backyard legume grown by nearly 70 percent of small-scale farmers in Zimbabwe and across Africa.

鈥淏ambara is a complete food, up to 25 percent protein, more than 60 percent carbohydrate and about 6 percent fat,鈥 Mavankeni said. She hopes to reduce the maturation time for the crop, and make it more disease resistant and drought tolerant.

Initially, the African Orphan Crop Consortium had planned to sequence the genome of about 16 indigenous crops, but that number grew when the group surveyed Africa鈥檚 agricultural leaders.

鈥淲e were told in order to have any impact on nutrition we would need to improve at least 100 crops,鈥 Shapiro said. 鈥淚n the end, we went with 101 crops, including the baobab tree, which can survive even the worst drought. You can eat its leaves, which are actually quite tasty.鈥

Other crops include the legume, pigeon pea, as well as a form of grain called finger millet, and spider plant, a leafy green vegetable that鈥檚 already about twice as nutritious as spinach.

A tall task 

The group collaborates with researchers all over the world, and all of its sequence information will be posted to the Web and offered free to anyone, on condition it not be patented.

鈥淏ecause we share all our information, we can build on each other鈥檚 research,鈥 said Allen Van Deynze, professional researcher with the 澳门六合彩开奖结果走势图 Department of Plant Sciences and a founding member of the consortium. 鈥淲e hope to have five genomes out for public review within the next six months.鈥 

Training plant breeders for the world

The 澳门六合彩开奖结果走势图 Plant Breeding Academy plans to train 250 breeders over the next five years in Africa, and those graduates are becoming partners in the orphan-crop effort.

Daniel Adewale, plant breeder with the Ondo State University of Science and Technology in Okitpupa, Nigeria, is using the skills he learned in the 2014 academy to improve the African yam bean, increasing its essential amino acid content and reducing its cooking time.

鈥淏y helping breeders improve these forgotten crops, I believe the African Orphan Crop Consortium will cure malnutrition in Africa,鈥 Adewale said.

A more fruitful revolution

Improved plant breeding, fertilizers and irrigation helped Asian countries turn food deficits into surpluses during the Green Revolution in the 1960s by producing vast amounts of corn, wheat and rice. For various reasons, that movement didn鈥檛 extend to Africa, but Professor Iago Hale from the University of New Hampshire, who also teaches at the 澳门六合彩开奖结果走势图 Plant Breeding Academy in Africa, predicts the orphan crops plant-breeding revolution will be more fruitful.

鈥淚t has a much better chance of success, because it focuses on species that are already adapted to the continent鈥檚 climates, environments and cultures,鈥 said Hale, who received his Ph.D. in horticulture and agronomy from 澳门六合彩开奖结果走势图 in 2011. 鈥淭he project focuses on the food people eat, not the food we think they should eat, from a global commodity perspective. I believe we will look back in a generation and understand this was the beginning of a new era in human well-being.鈥
