Figure 7From: The role of horizontal transfer in the evolution of a highly variable lipopolysaccharide biosynthesis locus in xanthomonads that infect rice, citrus and crucifersDeduced pattern of horizontal gene transfer at an LPS locus in Xanthomonas species. A hypothetical tree depicting putative horizontal gene transfer events (indicated by arrows) that gave rise to LPS gene clusters in different Xanthomonas species and pathovars.Back to article page
