Figure 1. Circular chromosome of Polymorphum gilvum SL003B-26A1^T.

The scale on the outside indicates the size. Position 1 of the chromosome was assigned to the first nucleotide of the dnaA gene. Rings 1 and 2 (from the outside in) indicate the genes in forward and reverse strands respectively, the colors of the genes indicate the COG categories, as indicated in the figure. Rings 3 and 4 indicate the G+C content and GC skew [(C−G)/(C+G)], respectively. Circular genome map was generated by CGview [78].
