Figure 2From: Inter- and intra-specific pan-genomes of Borrelia burgdorferi sensu lato: genome stability and adaptive radiationInter- and intra- species phylogenetic SNP trees for B. burgdorferi s. l. Maximum likelihood SNP trees were constructed as described in the Methods section, using the strains are described in Table 1. Well-supported bootstrap values for 1000 trials are shown above the branches (values for short branches are not shown), and lengths are given below the branches. In each panel a scale of fractional difference is shown. The four B. burgdorferi s.s. groups are indicated in red (see text).Back to article page
