ML tree of the TEF region of Graphilbum. Bootstrap values of ML/MP ≥ 70% are recorded at nodes as ML/MP and bold branches indicate posterior probability values ≥ 0.9. ML and MP, Bootstrap values < 70% are indicated by the symbol *. The tree is drawn to scale (see bar) with branch length measured in the number of substitutions per site. Strains representing ex-type sequences are marked with “T.” Abbreviations: ML, Maximum Likelihood; MP, Maximum Parsimony; BI, Bayesian Inference and the final alignment of 725 positions, including gaps.
