Distribution of genes involved in sensing and adhesion among lineages of Xanthomonas spp. Black and white squares represent the presence and the absence, respectively, of the corresponding gene in at least 80% of strains of a pathovar or a genetic lineage. Grey squares indicate that the presence of the gene is variable among strains of the lineage. Thirty one repertoire types were identified on the basis of the presence-absence of genes under study. At least three independent PCR reactions were performed to ascertain the presence/absence of each gene. X. a.: X. axonopodis; X. v.: X. vasicola; X. c.: X. campestris and X. o.: X. oryzae.
