FIG 5.

Maximum likelihood phylogenetic tree based on the concatenated alignment of the alpha and beta subunits of dissimilatory sulfite reductase (DsrAB) from family UBA6911 in relation to reference sequences. Genus UBA6911 sequences are shown in yellow, while genus Ga0212092 sequences are shown in purple. Reference sequences from phyla other than Acidobacteria are shown as gray wedges. Acidobacteria references are labeled by the subgroup number. Bootstrap support values are based on 100 replicates and are shown for nodes with >70% support.
