Evolutionary relationships of candidate division TM6. (A) Phylogenetic relationship of 16S rRNA gene sequences designated as members of TM6 in public databases reveal the global distribution and sequence diversity within this group. An asterisk indicates the TM6 sequences from this study. (B) Unrooted 16S rRNA gene tree based on maximum-likelihood analysis of representative candidate division TM6 and Proteobacteria sequences. One thousand bootstrapped replicate resampled datasets were analyzed. Bootstrap values are indicated as percentages and not shown if below 50%.
