A candidate RxLR effector from Plasmopara viticola can elicit immune responses in Nicotiana benthamiana.

ABSTRACT:

Background

Diverse plant pathogens deliver effectors into plant cells to alter host processes. Oomycete pathogen encodes a large number of putative RxLR effectors which are likely to play a role in manipulating plant defense responses. The secretome of Plasmopara viticola (downy mildew of grapevine) contains at least 162 candidate RxLR effectors discovered in our recent studies, but their roles in infection and pathogenicity remain to be determined. Here, we characterize in depth one of the putative RxLR effectors, PvRxLR16, which has been reported to induce cell death in Nicotiana benthamiana in our previous study.

Results

The nuclear localization, W/Y/L motifs, and a putative N-glycosylation site in C-terminal of PvRxLR16 were essential for cell death-inducing activity. Su
