Figure 1.

Collection locations (A, B; see table 1 for definitions) and phylogenetic construction (C) of symbiotic Pseudonocardia. The phylogeny was based on a six-locus concatenated alignment and used Bayesian methods. The scale bar corresponds to 0.005 substitutions per site. Maximum likelihood methods yielded trees with similar topologies. Bayesian posterior probabilities are reported below branches, and bootstrap support values from maximum likelihood are reported above branches. Highlighted isolates are recombinant.
