Sydney scientists solve 30 year wheat rust puzzle

Researchers from the University of Sydney, CSIRO, the United Kingdom’s John Innes Centre, Limagrain UK and the National Institute of Agricultural Botany (NIAB) have isolated the first major resistance genes against the stripe rust disease that is devastating wheat crops worldwide. The discovery by the scientists, who have cloned three related rust resistance genes – called Yr7, Yr5, and YrSP – will enable these important genes to be accurately monitored and integrated into breeding programs in the fight against ever-changing pathogens that could kill about 70 percent or more of whole wheat crops at a time.
