 === Genomic organization ===
-//xopJ6//  is present on a ca. 9-kb transposable element named Tn//6714//. It was found in multiple identical copies, likely due to recent transposition events (Lauber //et al//., 2024). Many //Xanthomonas campestris//  pv. //campestris//  strains do not contain any //xopJ6//gene and are still potent and adapted pathogenic strains (Lauber //et al//., 2024).

 === Regulation ===
