| Research Abstract |
Ralstonia solanacearum causes bacterial wilt disease in more than 200 plant species, including economically important Solanaceae species. R. solanacearum injects virulence factor proteins effectors into plant cytoplasm, then induces hypersensitive response (HR) in nonhost plants and disease in host plants. In this study we identified one effector Rip36 induces HR in the nonhost wild eggplant Solanum torvum in an Hrp-dependent manner. Rip36-induced HR requires the putative Zn-protease motif. On the other hand, Rip36 is a dispensable virulence factor to cause disease in eggplant, because rip36-defective mutants grew well in host eggplants as the wild type.
