Ejeta to give Sigma Xi lecture on honored research
Gebisa Ejeta, Distinguished Professor of Agronomy and recipient of 2009 World Food Prize, will present a Sigma Xi Distinguished Lecture at 1:30 p.m. Wednesday (March 24), discussing the research that gained him the award and has improved food supplies in his native Africa.
Ejeta has titled his talk "Out-witting the Witch: The Fascinating Biology of Witchweed (Striga) and its Genetic Control." The lecture will be in Fowler Hall, Stewart Center. A reception is to follow in the Stewart Center Gallery.
The World Food Prize is considered the "Nobel Prize" in agriculture. Ejeta, a plant breeder and geneticist, developed sorghum varieties resistant to drought and Striga, a parasitic weed. Sorghum is a major food crop for more than 500 million people on the African continent.
Ejeta's research areas include:
* Elucidate mechanisms of resistance to drought, Striga, and plant diseases in sorghum.
* Studying inheritance of traits associated with resistance to these traits.
* Characterizing genomic differences among botanical races and germplasm pools of sorghum.
* Development and enhancement of sorghum germplasm with increased levels of resistance to drought, Striga, and grain mold infection.
