Figure 2. Phylogenetic analysis of “Ca. Desulfopertinax cowenii,” “Ca. Desulforudis audaxviator” and other closely related dsrB and SSU rRNA genes.

Figure 2

Phylogenetic relationships between “Ca. Desulfopertinax cowenii,” “Ca. Desulforudis audaxviator,” and closely related dsrB genes (A) and a SSU rRNA gene related to “Ca. D. audaxviator” reconstructed from the U1362A metagenome via EMIRGE (B) lend additional support to a shared evolutionary history between “Ca. D. cowenii” and “Ca. D. audaxviator.” Black (100%), gray (≥80%), and white (≥50%) circles indicate nodes with bootstrap support, from 2,000 replicates. The scale bars correspond to 0.05 substitutions per nucleotide position. SSU rRNA gene sequences are colored according to their source location: blue, marine igneous basement; yellow, marine sediments; green, terrestrial subsurface; red, artificial (man-made).
