   * //Agrobacterium//-mediated transient expression of both //Xanthomonas oryzae// pv. //oryzae// 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).   * //Agrobacterium//-mediated transient expression of both //Xanthomonas oryzae// pv. //oryzae// XopQ and XopX in rice cells resulted in induction of rice immune responses.

   * A screen for //Xanthomonas oryzae// pv. //oryzae// 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).   * A screen for //Xanthomonas oryzae// pv. //oryzae// 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.
