Study finds large-scale expansion of stem rust resistance gene in barley and oat lineages

(American Phytopathological Society) Stem rust is one of the most devastating fungal diseases of wheat and historically has caused dramatic, widespread crop failures resulting in significant yield losses around the world. Stem rust epidemics in major wheat growing areas could cause a major threat to global food security. Scientists have identified a resistance gene, Sr22, as one of the few characterized genes that protects against a large array of stem rust races.
