Nonhost resistance of plants to powdery mildew—New opportunities to unravel the mystery

摘要: A better understanding of the genetics and molecular mechanisms underlying plant nonhost resistance, which is strong durable, bears potential for targeted employment this valuable trait to control host pathogens. However, because resistance operates at plant-species level, it often has been beyond reach breeding programs that are based on allele combination within a given crop species. Recently, use mutant gene-silencing approaches in Arabidopsis thaliana barley (Hordeum vulgare), together with development nonhost-susceptible lines, open up new possibilities discover genes involved unravel mechanisms. In many these studies, interactions appropriate inappropriate powdery mildew fungi, respectively, have used, therefore fulfil an important role as model systems study fungal
