Discovery of a novel powdery mildew (Blumeria graminis) resistance locus in rye (Secale cereale L.)

Abstract Powdery mildew is one of the most destructive diseases in the world, causing substantial grain yield losses and quality reduction in cereal crops. At present 23 powdery mildew resistance genes have been identified in rye, of which the majority are in wheat-rye translocation lines developed...
