Dynamics of Genome Rearrangement in Bacterial Populations
Figure 3
Consensus phylogenetic network of Yersinia based on inversions.
Consensus phylogenetic network for eight of the Yersinia listed in Table 1. Branch lengths are proportional to the average number of per-branch inversion events. Splits with Bayesian posterior probability (Bpp)>0.2 are shown in black, splits with Bpp between 0.1 and 0.2 in gray. To visualize the network at Bpp 0.2, imagine removing gray edges and straightening the black edges. The inversion phylogeny supports a Y. pestis clade, and at Bpp 0.2 it supports subclades which agree with SNP phylogenies [39]. Of note, internal branches in the Y. pestis are short relative to Y. pseudotuberculosis, suggesting either rapid population growth, subdivision, or other effects.
