Fig. 4: Phylogenomics of intestinal Caudovirales.
From: Metagenomic compendium of 189,680 DNA viruses from the human gut microbiome
A phylogenetic tree was constructed from 25,528 species-level genomes derived from the MGV and other databases (IMG/VR, HuVirDB and GVD). a, Phylogeny of intestinal Caudovirales. Tree was plotted using iToL74 and to improve visualization only one genome per genus-level vOTU is displayed. Branch colour indicates whether a lineage is represented by a previously published study (black) or is unique to the MGV catalogue (green). Outer rings display metadata for each vOTU. b, PD was calculated by taking the sum of branch lengths represented by species-level viral genomes. c,d, MGVs from the current study result in a large gain in PD, which is consistent across (c) viral families and (d) viruses infecting different host groups.
