Fig. 1: Phylogeny of recovered genomes with cultured and uncultured references, based on 37 conserved marker genes.

Bootstrap values over 70% are displayed with the proportional size of circles along internal branches. The two classes are shown to be distinct when compared to all NCBI database available Armatimonadota (100% bootstrap value). The two described classes: Hebobcteria and Zipacnadia are highlighted within the tree in green and purple. Aquificae was used as an outgroup to root the tree. The five metabolic clusters generated based on protein content are shown by the color of tree branches. Scores generated by MEBS are displayed by color blocks directly outside each corresponding branch label. An interactive version of this tree is available online at https://itol.embl.de/shared/2mUVQn1s5SIs8 as “Main Tree”.
