From the outside in, the outer black circle shows the scale line in Mbps; circles 2 and 3 represent the coding region with the colors of the COG categories; circle 4 and 5 show tRNA (green) and rRNA (red), respectively; circle 6 displays the IS elements (blue); circle 7 shows the genomic islands (orange); circle 8 represents mean centered G+C content (bars facing outside-above mean, bars facing inside-below mean); circle 9 shows GC skew (G−C)/(G+C). GC content and GC skew were calculated using a 10-kb window in steps of 200 bp.
