Maximum likelihood tree of the PVC subgroups analysed in this study. The tree was calculated based on the concatenated alignment of 17 ribosomal proteins and rooted with the Omnitrophota phyla. Only bootstraps > 90% were represented by purple dots on the branches. Colored dots reflect the biome of origin where reference genomes were recovered. White circles at the end of the branches indicate the number of putative large (> 5000 amino-acids) proteins identified in genomes. Novel genomes (n = 5) are labeled in bold. Yellow and brown arcs indicate the Auribacterota and Shingomicrobia clades, respectively
