Genome-based phylogeny of the class Planctomycetacia defined in the GTDB taxonomy. A selected part of the GTDB-Tk multiple alignment was used for tree construction in PhyML v. 3.3 with default parameters. The tree was inferred from the concatenation of 120 conserved bacterial marker genes. The support values for the internal nodes were estimated by approximate Bayes tests in PhyML. Taxonomy is shown according to the GTDB (o_, order; f_, family; g_, genus). Phycisphaera mikurensis, a member of the class Phycisphaerae, was used to root the tree.
