Silvano Assanga hopes his genetically modified wheat plants will improve farming in Africa.
As a child growing up in Kenya, Ph.D. student Silvano Assanga witnessed hunger first hand. “It can lead to human crisis for those who have been there and do not know what is happening underground,” said Assanga, who studies plant breeding. “It’s really touching and pushed me to pursue further studies to make a difference in the lives of those people, because for them, food means everything.” Assanga has received multiple awards, including his recent representation of Texas A&M at The Chicago Council on Global Affairs’ annual Global Food Security Symposium in May in Washington D.C. for his research on wheat breeding and genetics.
Assanga’s research focuses on wheat breeding and genetics — specifically with drought tolerance and rust — a significant problem that farmers all over the world are facing, especially in parts of Africa, Assanga said. “It also happens that water is a big issue globally,” Assanga said. “We’re searching for different varieties that can use less water but produce more in the farmer’s field.” Shuyu Liu, assistant professor at the Texas A&M AgriLife Research and Extension center in Amarillo, Texas, who is currently working Assanga on his research, said they are working with two different wheat plant genes. “One is rust resistant,” Liu said. “Another one is adapted to drought, such as in the U.S, the high plains.” Every year the drought conditions
continue to worsen, limiting wheat production in African countires — especially Kenya, Assanga’s home country, Liu said. Assanga said he and Liu are gathering data from the field before it can be put into publication, but they have made progress. There are regions of the wheat genome that are responsible for drought and rust, and they are currently marking chromosomes in which they believe are exercising drought and rust tolerance, Assanga said. Amir Ibrahim, professor and small grains breeder and geneticist, said that Assanga’s research will carry forward some of Dr. Norman Borlaug’s attempts to aid Africa. See Superplants on page 7
