-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.
