Figure 1.
Phylogenetic placement of Sodalis and related symbiotic bacteria within Gammaproteobacteria based on 16S rRNA and ITSglu concatenation. A Bayesian tree, inferred from a total of 2,467 unambiguously aligned nucleotide sites, with support values indicating Bayesian posterior probabilities (PP)/MP bootstrap (BS) is shown. PP indicated as percentage, i.e., PP = 0.95 is depicted as 95. Branches constrained with MP are shown in bold. For insect symbionts, host species are indicated. S = symbiont, SS = S-symbiont, PS = P-symbiont. Scale bar represents substitutions/site.
