Figure 1. Alignment of the genomes of CB9615, Sakai and EDL933.

Scales are Mbp. The grey and yellow shaded regions represent segments present in all strains, with inverted segments shaded in yellow. Purple and cyan boxes within the grey or yellow regions represent the indels of phages or phage-like elements (insertions and deletions respectively) defined in Table S9. Red and green boxes represent other major indels (insertions and deletions respectively) that involve the changes of the gene numbers in Table S10, with the indel numbers also shown as defined in Table S9. The orange boxes indicate the E. coli O157:H7 O-antigen segment gained by recombination. Figure S1 is a greatly expanded version of this figure showing individual genes.
