Pathogenicity of Xanthomonas and most other Gram-negative phytopathogenic bacteria depends on a conserved type III secretion (T3S) system which injects more than 25 different effector proteins into the plant cell. Extensive studies in the last years on the molecular mechanisms of type III effector function revealed that effector proteins with enzymatic functions seem to play important roles in the interaction of Xanthomonas with its host plants, for example, the SUMO protease XopD. In addition, xanthomonads express a unique class of type III effectors to pursue another strategy. Effectors of the AvrBs3 family, so far only identified in Xanthomonas spp. and Ralstonia solanacearum, mimic plant transcriptional activators and manipulate the plant transcriptome.
