Fig. 2. Phylogenetic tree of the hydrothermal plume and deep-sea-derived MAGs based on the concatenated 16 ribosomal protein alignment (RP16 tree).

Functional traits associated with carbon, nitrogen, sulfur, hydrogen cycling, and oxygen respiration are shown. Filled and unfilled circles denote the presence/absence of function traits within a genome. This tree was visualized using iTOL [96] (https://itol.embl.de/). This figure does not necessarily reflect the branching order of all representative Proteobacteria groups.
