FIG 4.

Phylogenomic tree of Gemmatimonadota genomes based on 400 universally conserved and most ubiquitous proteins present in the PhyloPhlAn database (42, 43). The collapsed branch represents an outgroup consisting of three genomes from the bacterial phylum Fibrobacterota (GCA_900142455.1 Hallerella intestinalis, GCA_900217845.1 Fibrobacter elongatus, GCA_000146505.1 Fibrobacter succinogenes). The strength of support for internal nodes is shown through gray-scale-colored circles (center legend). All genomes are color-coded based on their environmental origin (center legend). The following annotations, starting from innermost to outermost indicate GC content (%), estimated genome size (Mb), and family level classification. The legend for each outer circle is represented in the upper left corner. Details on all genomes can be found in Tables S1 and S2.
