Fig. 8

In panel A, each dot indicates distance to the nearest neighbor from an E. coli genome, measured either as RMS correlation distance (x-axis) or whole-genome p-distance (y-axis). The grey dots are the results for all 1066 genomes, and the black dots are for the 54 genomes left after clustering with maximum condition value 100. In panel B, the neighbor-joining tree is based on the p-distances between all strains, and the black tips indicate the cluster centroid genomes
