Figure 2.

Phylogenetic position of Xanthomonas euvesicatoria, X. vesicatoria, and nineteen other plant pathogenic xanthomonads relative to each other. The phylogenetic tree was obtained using concatenated gene sequences for chromosomal replication initiator factor (dnaA), type I glyceraldehyde-3-phosphate dehydrogenase (gapA), DNA topoisomerase (ATP-hydrolyzing) subunit B (gyrB), hydroxymethylbilane synthase (hmbs), and pyruvate dehydrogenase (pdg) genes. Numbers on the nodes represent bootstrap values and are presented as percentage of 1000 replicates. The scale bar at the bottom shows the distance between strains of other species and strains of X. euvesicatoria and X. vesicatoria sequenced in this study. Sequences for other Xanthomonas species were extracted from the genomes listed in Table 3. LM159 and LMG930 are reference strains for X. vesicatoria and X. euvesicatoria, respectively.
