Seed Today - Q1 2009 - (Page 73) Cold-Tolerant Wheat Genes UC-Davis identifies wheat genes that confer cold tolerance The tolerance for freezing temperatures varies in different winter wheat varieties, ranging from one to 10 degrees Fahrenheit. To date, wheat breeders have had limited success at developing cultivars that exhibit improved freezing tolerance, due in part to the regulation of temperature tolerance by multiple genes. Professor Jorge Dubcovsky, a wheat breeder and geneticist, led an international team of scientists that identified frost-susceptible varieties and determined which genes regulate temperature tolerance in wheat. The research team had previously identified a compact group of 11 genes on wheat chromosome 5AL. They then demonstrated that the frost-tolerant variety activated two of these genes earlier than frost-susceptible varieties. “Our next step is to further examine differences in freezing tolerance among winter wheat varieties to determine which genes are present and active in the hardiest varieties, such as from Russia, the Ukraine, Canada, western Nebraska, and other locations with extremely severe winters,” says project collaborator Dr. Kim Garland-Campbell. The project team will use these discoveries to screen wheat varieties for the best combinations of frost tolerance genes and then develop genetic markers to accelerate the selection of hardier wheat cultivars. "The identification of these optimum gene combinations will enable breeders to develop hardier winter wheat, which is of vital importance in light of growing pressures to increase global food production," Dubcovsky says. Cold-tolerant wheat With funding from USDA’s Cooperative State Research, Education, and Extension Service (CSREES), scientists at the University of California-Davis have identified genes in wheat that are responsible for the the plant’s tolerance to freezing temperatures.
