Figure 1. Genomic map of ST131 E. coli EC958.

Figure 1

The inner circle represents the reference sequence, E. coli EC958, with scaffolds of the draft assembly displayed as alternating blue or red color in the inner-most ring. Outer rings show shared identity (according to BLASTn) with individual UPEC genomes and various other E. coli genomes. BLASTn matches between 80% and 100% nucleotide identity are colored from lightest to darkest shade, respectively, according to the graduated scale on the right of the circular BLAST image. Matches with less than 80% identity, or E. coli EC958 regions with no BLAST matches, appear as blank spaces in each ring. Rings indicate BLAST identity, from inside to out, between EC958 and: (1–5) individual UPEC genomes CFT073, 536, UTI89, IAI39, UMN026 (light to dark blue); (6) pooled ExPEC genomes: APEC O1, IHE3034, S88 (purple); (7) pooled EHEC/EPEC genomes: EC4115, Sakai, EDL933, E2348 (pink); (8) pooled EAEC/AIEC/ETEC genomes: 55989, O42, LF82, E24377A (yellow); (9) environmental E. coli genome: SMS_3_5 (lime green); (10) pooled commensal E. coli genomes: IAI1, SE11, SE15, HS, 8739, ED1a (teal); pooled E. coli K12 genomes: MG1655, W3110, DH10B (green). Black labels indicate regions that are known to be variable in E. coli genomes. Blue labels and arcs indicate RODs that appear to be prophage regions; red labels and arcs indicate known genomic islands (GI-pheV, GI-selC, GI-thrW, and GI-leuX) or potential new genomic islands (ROD1–3). The image was prepared using Blast Ring Image Generator (http://sourceforge.net/projects/brig).
