Employing genetic resistance to protect durum wheat in the battle against stem rust |
|
Durum wheat, an essential staple crop around the world, is under constant threat from stem rust. How can breeders get ahead of a rapidly mutating pathogen that overcomes existing resistance genes? Doctoral student Shitaye Megerssa and colleagues at Cornell, CIMMYT, EIAR, and USDA-ARS investigate more effective genetic resistance strategies.

Richard Michelmore, Director U.C. Davis Genome Center |
|
By repurposing an LGC IntelliQube machine normally used to genotype plant DNA samples for agricultural research, the UC Davis Genome Center directed by Richard Michelmore is helping test and protect an entire community in California against COVID-19. We are proud to have Dr. Michelmore on the advisory committee for our Delivering Genetic Gain in Wheat (DGGW) project.
“The testing and analysis of variants is a logical extension of my long-standing interest in plant disease pandemics, such as the wheat rusts," Michelmore told the BGRI. "Diagnostics will never be the same again; hopefully, some of the new technologies and excess testing capacity after the end of the COVID pandemic can be applied to plant pathogens."

Morocco’s Wheat Sector: Higher Productivity is Within Reach
News: ICARDA
|
|
A recent study by ICARDA scientists analyzed Morocco’s wheat sector to identify areas where productivity can be increased to boost smallholder farmers’ yields and income. To this day, Morocco only produces about 58% of its needs in wheat and struggles to satisfy the ever growing local demand. To meet its cereal needs, Morocco’s imports have steadily increased over time, to 42% for the last 10 years. |
