| The XopH effector, also known as AvrBs1.1 (White //et al//., 2009), was first reported in 1988 (Ronald and Staskawicz 1988) and discovered due to its virulent activity (Gurenn //et al//., 2006). Later, this effector began to be identified based on the coregulation with the TTS system (Gurlebeck //et al//., 2006), most recently began to be identified by a combination of biochemical approaches, including a new NMR-based method to discriminate inositol polyphosphate enantiomers (Blüher //et al//., 2017). | The XopH effector, also known as AvrBs1.1 (White //et al//., 2009), was first reported in 1988 (Ronald and Staskawicz 1988) and discovered due to its virulent activity (Gurenn //et al//., 2006).
