The cytosolic iron-sulphur cluster assembly mechanism in grapevine is one target of a virulent Crinkler effector from Plasmopara viticola.

ABSTRACT: Grapevine downy mildew is one of the most devastating diseases in grape production worldwide, but its pathogenesis remains largely unknown. A thorough understanding of the interaction between grapevine and the causal agent, Plasmopara viticola, is helpful to develop alternative disease control measures. Effector proteins that could be secreted to the interaction interface by pathogens are responsible for the susceptibility of host plants. In this study, a Crinkler effector, named PvCRN17, which is from P. viticola and showed virulent effects towards Nicotiana benthamiana previously, was further investigated. Consistently, PvCRN17 showed a virulent effect on grapevine plants. Protein-protein interaction experiments identified grapevine VAE7L1 (Vitis protein ASYMMETRIC LEAVES 1/2 ENHANCER 7-
