Plasmopara viticola effector PvRXLR159 suppresses immune responses in Nicotiana benthamiana.

ABSTRACT: Plasmopara viticola, the causal oomycete of grapevine downy mildew disease, secrets a series of RXLR effectors to manipulate host immunity. In this study, we characterized the role of a RXLR effector of P. viticola, PvRXLR159, in plant-microbe interaction. Transcription of PvRXLR159 in P. viticola was induced in the early stage of infection in grapevine (Vitis vinifera 'Thomson Seedless'). Further results revealed that PvRXLR159 contains a functional signal peptide and its C terminus was essential to inhibit cell death by elicitors, INF1 and BAX, in Nicotiana benthamiana. Transient expression of PvRXLR159 suppressed N. benthamiana resistance to a pathogenic oomycete, Phytophthora capsici. Taken together, we propose that PvRXLR159 is induced and secreted by P. viticola to suppress host resistance.
