FIG 5.

Phylogenetic relationships among 8VR protein sequences compared with parent organism 16S rRNA phylogenies. Maximum-likelihood phylogenies of BciA (A) and BciB (B) homologs, compared with 16S rRNA phylogenies of the same organisms, are shown. The BciA and BciB trees were constructed from amino acid alignments using the PROTGAMMAAUTO model in RAxML version 8.2.4. The rRNA trees were constructed from nucleotide alignments using the GTRCAT model. The numbers on branches indicate the percent bootstrap support from 100 replicates, and the scale bars indicate the specified number of amino acid or nucleotide substitutions per site. Example organisms from cyanobacteria (cyan), purple nonsulfur bacteria (purple), green sulfur bacteria (green), green filamentous bacteria (amber), and Acidobacteria (red) are included.
