Maximum likelihood phylogeny based on concatenated core genes from 65 genomes of X. euvesicatoria and X. perforans, rooted with Xanthomonas citri subsp. citri strain A306. X. euvesicatoria strains are highlighted in yellow and X. perforans strains in purple. Strains NI1 and NI38, from Nigeria, are shown in green letters, Italian strain 4P1S2 in red letters, and the atypical X. euvesicatoria strain LMG918 in orange letters. X. axonopodis pv. allii, and four X. alfalfae subsp. alfalfae strains have >96% ANI with X. euvesicatoria and X. perforans strains. Bar, substitutions per site. The tree was generated using IQ-TREE (v1.5.5) with the general time-reversible model and a proportion of invariant sites (GTR+I). Branch support was assessed by ultrafast bootstrap analysis using 1,000 replicates.
