Whole-Genome Comparison of Five <i>Campylobacter</i> Strains

<p>Line figures depict the results of PROmer analysis. Colored lines denote percent identity of protein translations and are plotted according to the location in the reference (C. jejuni RM1221, x-axis) and query genomes (C. jejuni NCTC 11168 [upper y-axis] and C. coli RM2228 [lower y-axis]) (A). The Venn diagrams show the number of proteins shared (black) or unique (red) within a particular relationship for all five <i>Campylobacter</i> strains (B) and for members of the sequenced ε-Proteobacteria compared in this study (C). Protein sequences binned as “unique” are unique within the context of the genomes plotted and the cutoffs used to parse the BLASTP data. The pie charts plot the number of protein sequences by main functional role categories for C. jejuni RM1221 ORFs. A frequency distribution of protein percent identity (D) was computed: specifically, the number of protein sequences within class intervals of 5% amino acid identity from 35% to 100% that match C. jejuni RM1221 reference sequences were plotted.
