Query: Rsc3K, a SMV resistance gene localized on chromosome 2 in soybean cv. Kefeng No.1, interacts with virulence determinant P3 Soybean mosaic virus (SMV) is one of the most devastating viral pathogens in Glycine max (L.) Merr (soybean). Twenty-two SMV strains (SC1-SC22) isolated in China were identified based on their responses to ten soybean cultivars. By using the F2-derived F3 (F2:3) and recombinant inbred line (RIL) populations of resistant Soybean cultivar (cv.) Kefeng No.1 x susceptible cv. Nannong 1138-2, we localized the gene mediating resistant to SMV-SC3 strain to a 90 kb interval on chromosome 2 in Kefeng No.1. Bean pod mottle virus (BPMV)-induced gene silencing (VIGS) were used to study the gene function of candidate genes in the mapping interval and revealed that an recombinant gene, later named as Rsc3K, caused by internal deletion of a genomic DNA frag ement in Kefeng No.1, is the resistant gene to SMV-SC3. By shuffling genes between avirulent isolate SC3 and avirulent SMV isolate 1129, we found that P3 is the virulence determinant causing resistance on Kefeng No.1. We showed the interaction between Rsc3K and P3 by the yeast two-hybrid (Y2H) and bimolecular fluorescent complementation (BiFC) assays. In conclusion, this study demonstrated that Rsc3K plays a crucial role in resistance of Kefeng No.1 to SMV-SC3 by direct interaction with viral protein P3.
