   * Roq1 was found to confer immunity to //Xanthomonas//  (containing XopQ), //P. syringae//  (containing the XopQ homolog HopQ1), and //Ralstonia//  (containing the XopQ homolog RipB) when expressed in tomato (Thomas //et al.//, 2020).   * Roq1 was found to confer immunity to //Xanthomonas//  (containing XopQ), //P. syringae//  (containing the XopQ homolog HopQ1), and //Ralstonia//  (containing the XopQ homolog RipB) when expressed in tomato (Thomas //et al.//, 2020).
   * Strong resistance to //Xanthomonas euvesicatoria//  pv. //perforans//  was observed with transgenic tomato plants expressing Roq1 from //N. benthamiana//  in three seasons of field trials with both natural and artificial inoculation. The Roq1 gene can therefore be used to provide safe, economical, and effective control of these pathogens in tomato and other crop species and reduce or eliminate the need for traditional chemical controls (Thomas //et al.//, 2020).   * Strong resistance to //Xanthomonas euvesicatoria//  pv. //perforans//  was observed with transgenic tomato plants expressing Roq1 from //N. benthamiana//  in three seasons of field trials with both natural and artificial inoculation.

 +  * Agrobacterium-mediated transient expression of both XopQ and XopX in rice cells resulted in induction of rice immune responses. These immune responses were not observed when either protein was individually expressed in rice cells. XopQ-XopX induced rice immune responses were not observed with a XopX mutant that is defective in 14-3-3 binding (Deb //et al.//, 2020).
 +  * A screen for //Xanthomonas//  effectors which can suppress XopQ-XopX induced rice immune responses, led to the identification of five effectors, namely XopU, XopV, XopP, XopG and AvrBs2, that could individually suppress these immune responses. These results suggest a complex interplay of //Xanthomonas//  T3SS effectors in suppression of both pathogen-triggered immunity and effector-triggered immunity to promote virulence on rice (Deb //et al.//, 2020).
