i) the gum gene cluster for extracellular polysaccharide synthesis, ii) the hrp gene cluster for Type III secretion, iii) the gene cluster for lipopolysaccharide (LPS) synthesis, iv) the rpf gene cluster for regulation of pathogenicity, the Type II Secretion System coding gene clusters v) xcs and vi) xps, vii) the gene cluster for the most common Type IV Secretion System in Xanthomonas and viii) the flagellar biosynthesis genes. Gene clusters retrieved in each genome are labeled with the locus tags of their respective first and last genes (names given between parentheses). a virD4 absent in this gene region, but replaced by divergent homolog elsewhere in the genome, b virB5 and virB6 missing, call genes except virD4, virB8 and virB9 missing.
