Co-immunoprecipitation (Co-IP) in Nicotiana benthamiana followed by liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS)


ABSTRACT: Ralstonia solanacearum species complex causes bacterial wilt in variety crops. Tomato cultivar Hawaii 7996 is a widely used resistance resource, however, the resistance is evaded by virulent strains with underlying mechanisms still unknown. Here, we reported that phylotype II strain ES5-1 can overcome Hawaii 7996 resistance. RipV2, a type Ⅲ effector specifically to phylotype Ⅱ strains, is vital in overcoming tomato resistance. RipV2, which encodes a novel E3 ubiquitin ligase, suppresses immune responses and TNL-mediated cell death. Tomato helper NLR N requirement gene 1 (NRG1), enhanced disease susceptibility 1 (EDS1), and senescence-associated gene 101b (SAG101b) were identified as RipV2 target proteins. RipV2 is essential for ES5-1 virulence in Hawaii 7996 but not in SlNRG1-silenced tomato, demonstrating SlNRG1 to be the bona fide RipV2 virulence target. Our results dissected the mechanisms of RipV2 in disrupting immunity and highlighted the importance of converged immune components in conferring bacterial wiltresistance.
