Rice grassy stunt virus (RGSV), a member of the genusTenuivirus, causes serious rice disease in Southeast Asian countries. In this study, a green fluorescent protein (GFP)-based transient expression assay was conducted to show that p5, encoded on RNA5 in the viral sense, is a viral suppressor of RNA silencing (VSR). Protein-protein interactions (PPIs) between p5 and all RGSV proteins except pC1 and pC2 were investigated using Gal4-based yeast two-hybrid (Y2H) experiments. The results demonstrated that p5 interacts with itself and with p3 encoded on RNA3 in the viral sense. p5-p5 and p5-p3 interactions were detected by bimolecular fluorescence complementation (BiFC) assay, and the p5-p3 interaction was confirmed by subcellular co-localization and co-immunoprecipitation (Co-IP) assays. Using the Y2H system, we demonstrated that the p5-p3 interaction requires both the N-terminal (amino acid residues 1 to 99) and C-terminal (amino acid residues 94 to 191) domains of p5. In addition, either p5 or p3 could enhance the pathogenicity of potato virus X (PVX) inNicotiana benthamianaplants. A much more significant enhancement of PVX pathogenicity and accumulation was observed when p5 and p3 were expressed together. Our data also showed that RGSV p3 does not function as a VSR, and it had no effect on the VSR activity of p5 or the subcellular localization pattern of p5 in plant cells fromNicotiana benthamiana.
