Fig. 7. Phylogeny of gene cluster GC_00000823, annotated as K00373 Nitrite Oxidoreductase Subunit A.

Fig. 7

A Displays the phylogeny of the gene cluster rooted at the branch separating the majority of the Nitrospirota sequences from the Nitrospinota sequences. The LG + G4 model was used, as chosen by the B.I.C by ModelFinder. A highly divergent sequence from GCA_016212295 (Nitrospinota) was removed from the left panel for ease of visualization. This sequence can be seen as a diverged relative of Nitrotoga nxrA sequences on the right panel. B Displays gene cluster GC_00000823 sequences with all nxrA from GenBank. Respiratory narG from Desulfobacterota was included as well as tetrathionate reductase A (ttrA) from Desulfobacterota, that was used as an outgroup. The LG + I + G4 model was used, as chosen by the B.I.C by ModelFinder. The sequence from Nitrospirota assembly GCA_003354025, which branches closer to the Nitrospinota in the left panel is within the Planctomycetota on the right panel.
