Fig 2.

Circular view of whole-genome alignments of the chromosome of Agromonas oligotrophica S58. The outermost circle and the second circle show the positions of the putative protein-coding genes in clockwise and counterclockwise directions, respectively. The third and fourth circles from the outside represent BLASTn comparisons with Bradyrhizobium sp. BTAi1 (red) and Bradyrhizobium sp. ORS278 (green), respectively (E-value < 10⁻¹⁰). The innermost and second-innermost circles show the GC (guanine-cytosine) skew (green and purple) and the GC content (black), respectively. The GC skew circle shows the deviation from the average GC content of the entire sequence (higher-than-average GC content is shown in green; lower-than-average GC content is shown in purple). The marking inside the innermost circle represents genome positions in megabases. The positions of the putative replication origin, putative replication terminus, nitrogen fixation genes, and photosynthetic genes are shown outside the outermost circle. T3SS, type III secretion system.
