 In nature plants are subjected to attack by many potentially pathogenic microorganisms. Plants employ different mechanisms to defend themselves against such intruders. Powdery mildew of barley caused by the fungal pathogen (Blumeria gramins f.sp. hordei) is one of the most important diseases of barley in Europe and many major barley cultivation areas. We set out an integrated approach combining gene mapping and candidate gene analysis in order to identify genes that are responsible for natural variation in the level of basal resistance of barley to powdery mildew. Furthermore, we developed two experimental barley lines with exceptional susceptibility to a non-adapted form of Blumeria gramins, the wheat powdery mildew fungus. The developed lines will serve to elucidate the genetic basis of non-host resistance in barley to wheat powdery mildew. Identification of the genes that are responsible for defense reaction of plants may help breeders to design effective breeding strategies to deploy such genes in breeding programmes.
