Classification scheme of virophage genomes and details of new clades. a Maximum likelihood phylogenetic tree of HQ virophage genomes, i.e., virophage sequences > 10 kb containing the four core genes, based on the concatenated alignment of MCP, mCP, ATPase, and PRO. Each of the 27 clades corresponds to a proposed clade. The scale bar represents substitutions per site. Branch support values are shown at each node and indicated in the legend. b Virophage clade (Vp.cl) identifier. Names of clades containing previously reported virophage genomes include the name of one known virophage (e.g., OLV-cl14). Names of the new clades are shown in red. c The distribution of MCP models best hit in the virophage clade. d Synteny structure of the four core virophage genes of the HQ virophage genomes. e The proportion of the members of each clade with the syntenic organization shown in d. f Habitat types of all the sequences in a clade with their color code description in the captions below. g Genome length distribution of the virophage genomes per clade. h Total number of virophage genomes with circular genomes (blue) or linear genomes with inverted terminal repeats (orange) per virophage clade. Note that g and h only display the information for the 89 complete virophage genomes
