Quantifying bacterial evolution in the wild: A birthday problem for Campylobacter lineages
Fig 4
Mutation and recombination in C. coli and C. jejuni.
Average genome-wide NC positions (red dots = synonymous NCs, blue dots = nonsynonymous NCs) per isolate pair in relation to inferred recombined regions (grey blocks). Each plot represents one pair of isolates considered in rate calibration for C. coli (A) and C. jejuni (B) and are ordered according to S2 Table. y axis = number of NCs in relation to particular bp position of the reference genome (C. coli = YH501, C. jejuni = NCTC11168) and varies between pairs. x axis = position of reference genome in bins of 10,000 bp. The cladogram shows the relatedness of isolate pairs based on nucleotide identity, scale bar indicates NCs per site. It is evident from both A and B that recombination is the main source of variation in C. coli and C. jejuni.
