Strain related orthology maps. Strain related orthology maps. Each map shows comparative analysis based on each genome. From outside to inside: ring 1, gene positions according with COG categories color code; ring 2, GC content; ring 3, GC Skew; ring 4, island positions (color code according with islands legend); rings 5 to 8 show the BLAST homology for each gene versus the other four genomes (color code according with genomes legend).
