When Whole-Genome Alignments Just Won't Work: kSNP v2 Software for Alignment-Free SNP Discovery and Phylogenetics of Hundreds of Microbial Genomes
Figure 4
Maximum Likelihood tree of 68 finished E. coli genomes.
The tree is shown in the radial (unrooted) cladogram format in which branches are drawn without reference to branch lengths. Colored dots indicate pathogenicity phenotype. Arrows indicate branches that can be removed to create particular clusters (see text). Numbers at the internal nodes indicate the number of alleles that are shared exclusively by the descendants of each node. Numbers in parentheses following the genome names are exclusive to that genome.
