Figure 2

Circular representation of the N. cyriacigeorgica chromosome. Scale is in megabases and indicated on the outer black circle. The orange bar indicates position of the replication terminus. Black arrows show correspondence between RGP and low G + C content. Moving inward, the second circle indicates putative virulence genes (red); the third circle indicates conserved synteny groups (≥ 5 CDS) between N. cyriacigeorgica, N. farcinica, R. jostii and M. tuberculosis (blue); the fourth circle indicates tRNA genes (black), phage related genes (soft pink) and IS (purple); the fifth circle indicates selected regions of genomic plasticity i. e. RGP-Cy1 to RGP-Cy22 (green; also see Table 2); the sixth circle indicates the largest CDS observed (pink) and the seventh circle shows GC plot of the N. cyriacigeorgica genome.
