Minimum evolutionary tree of the White Point VAF and diverse sulfur-oxidizing gamma proteobacteria, based on 16S rRNA gene sequences. Sequences of epsilon proteobacteria are included as an outgroup. The tree was constructed with an alignment of positions 126 to 1376 (E. coli numbering). Numbers on the nodes represent percentage bootstrap values greater than 50% (1,000 replicates). Accession numbers are shown.
