 Lesions caused by mutants of X. citri on avrXacE2 show more extensive necrotic areas relative to those caused by wild-type bacteria in citrus leaves and grow slowly compared to wild type strain. This protein may function to attenuate cell death. No effect has been revealed on hypersensitive response (HR) on non-host plants (Dunger //et al//., 2012). Lesions caused by mutants of X. citri on avrXacE2 show more extensive necrotic areas relative to those caused by wild-type bacteria in citrus leaves and grow slowly compared to wild type strain.

-Not known.+In //X. citri //subsp. //citri //A306 the gene coding for XopE3 is in a region hypothesized to be a genomic island (Moreira //et al.//, 2010). This region or parts of it are conserved in many Xanthomonas strains, as shown by a genomic neighborhood search in the Integrated Microbial Genomes platform. In particular, in this search gene XAC3225 is nearly always adjacent to XAC3224 (//xopE3//), suggesting that the protein coded by XAC3225 is an interaction partner of XopE3. Moreira //et al.// (2010) commented on this as follows: "Next to //xopE3// (XAC3224) we find gene XAC3225, whose product is annotated as tranglycosylase //mltB//. This gene has strong similarity (e-value 10<sup>-133</sup>  , 100% coverage) to //hopAJ1// from //P. syringae// pv. //tomato// strain DC3000, where it is annotated as a T3SS helper protein. Although the //hopAJ1// gene is not itself a T3SS substrate, it contributes to effector translocation (Oh //et al.//, 2007). A mutant with a deletion of XAC3225 has reduced ability to cause canker (mutant phenotypes include a reduction in water soaking, hyperplasia, and necrosis compared to wild type) (Laia //et al.//, 2009)".
