Phylogenetic analysis of the integron integrase gene in bacteria. The phylogenetic tree shows that Xanthomonas has appeared as the parental species for the integron integrase gene, and Vibrio spp. and Bacteria multi spp. make separate single clade. In contrast, Aliivibrio Wodan is up to Shewanella, which includes 13 species that make a distinct clade. Three other small clades are also presented in the phylogenetic tree. The analysis shows that the integrons of different clades are more diverse, showing that the amino acid identity is very low and yet to be classified.
