Figure 4From: The role of horizontal transfer in the evolution of a highly variable lipopolysaccharide biosynthesis locus in xanthomonads that infect rice, citrus and crucifersNucleotide level comparison of LPS gene clusters of three strains of Xcc and one strain of Xca. Grey bars represent the LPS loci of the strains, as indicated. Comparisons were carried out using the BLASTN option of Artemis Comparison Tool (ACT). Bright red colour indicates a high level of nucleotide identity (95 to 100%) and gaps indicate highly diverged regions.Back to article page
