^РЕФ: RNA silencing is one of the main defence mechanisms employed by plants to fight pathogens. p19 protein encoded by the tomato bushy stunt virus (TBSVp19) is known as a suppressor of RNA silencing via siRNA sequestration to prevent the assembly of RISC. To better understand the impact of TBSVp19 on silencing and its roles in Phytophthora pathogens, we used the transient expression assay in Nicotiana benthamiana and found that the leaves expressing TBSVp19 were more susceptible to Phytophthora parasitica. Furthermore, we demonstrated that TBSVp19-mediated plant susceptibility in N. benthamiana is dependent on RNA-dependent RNA polymerase 6 (RDR6). We also tested the role of RNA silencing in resistance of soybean hairy roots to Phytophthora. The lesion size induced by P. sojae on TBSVp19-expressing soybean hairy roots was slightly, but significantly larger than GFP-expressing soybean hairy roots. Finally, the Arabidopsis gene silencing mutants ago1-27, zip-1, sgs3-11 and rdr6-11 were also examined for their resistance to P. parasitica. The results clearly showed that resistance levels of the mutants were visibly reduced compared with the wild type. Taken together, these results suggest that the gene silencing system in plants is essential for resistance to Phytophthora pathogens. aref1
