Mechanisms of powdery mildew resistance in the Vitaceae family.

ABSTRACT: The cultivated grapevine, Vitis vinifera, is a member of the Vitaceae family, which comprises over 700 species in 14 genera. Vitis vinifera is highly susceptible to the powdery mildew pathogen Erysiphe necator. However, other species within the Vitaceae family have been reported to show resistance to this fungal pathogen, but little is known about the mechanistic basis of this resistance. Therefore, the frequency of successful E. necator penetration events, in addition to programmed cell death (PCD) responses, were investigated in a representative genotype from a range of different species within the Vitaceae family. The results revealed that penetration resistance and PCD-associated responses, or combinations of both, are employed by the different Vitaceae genera to limit E. necator infec
