Unrooted ML tree of the DnaK protein. The tree was inferred with TreeFinder with the LG + Γ4 model (107 sequences and 444 positions). Numbers at nodes represent bootstrap values (100 replicates of the original alignment) and Bayesian posterior probabilities computed with TreeFinder and MrBayes, respectively (only values >50% and 0.5 are shown, dashes indicate that the corresponding support is inferior to the threshold, whereas when both supports are inferior to the thresholds no support values are indicated). The scale bar represents the average number of substitutions per site.
