-Yes. XopAD has homologues encoded in the genomes of most //Xanthomonas// species (Teper //et al.//, 2016), including //X. axonopodis// (Harrison & Studholme, 2014), //X. vasicola// (Studholme //et al//., 2010; Wasukira //et al.//, 2012), //X. nasturtii// (Vicente //et al.//, 2010), //X. citri// (Escalon //et al.//, 2013). In this respect, //Xanthomonas campestris// appears to be an exception. Escalon and colleagues state: “The analysis of //xopAD// //and// //xopAG// suggested horizontal transfer between //X. citri// pv. //bilvae//, another citrus pathogen, and some //X. citri// pv. //citri// strains” (Escalon //et al//., 2013). The prototype sequence from //X. euvesicatoria// pv. //euvesictoria// strain 85-10 (Teper //et al.//, 2016) is 614 amino acids in length and marked in GenBank as a fragment. Homologues in other genomes of this species range from 2840 aa (RefSeq: [[https://www.ncbi.nlm.nih.gov/protein/WP_046939801.1|WP_046939801.1]]) to 2885 aa (RefSeq: [[https://www.ncbi.nlm.nih.gov/protein/WP_033837371.1|WP_033837371.1]]) in length and the authors of the prototype study state: "We hypothesize that the ORFs annotated as XCV1197 (XopAV) and XCV1198, and XCV4315 (XopAD), XCV4314 and XCV4313, were originally two complete ORFs that were later truncated by the introduction of early stop codons" (Teper //et al//., 2016). Therefore, the full-length homologues found in other genomes might not be functionally equivalent to the prototype XopAD. The introduction of early stop codons is explained by presence of an IS//Xac5//-related insertion sequence (Escalon //et al.//, 2013).
