The realm Duplodnaviria includes viruses of archaea, bacteria and eukaryotes, with linear dsDNA genomes. Duplodnavirians share a distinct morphogenetic module of four hallmark genes encoding the HK97-fold major capsid protein, a genome packaging ATPase-nuclease (large terminase subunit), a portal protein and a capsid maturation protease. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the realm Duplodnaviria, which is available at ictv.global/report/duplodnaviria.
