ICTV Virus Taxonomy Profile: Apasviridae 2026

The family <i>Apasviridae</i> includes dsDNA viruses associated with the marine archaeal lineage <i>Poseidoniales</i>. Members of this family have been identified using metagenomic analyses of brackish estuarine samples and are related to other 'magroviruses' infecting <i>Poseidoniales</i> archaea. The family belongs to the order <i>Magrovirales</i> and includes the genus <i>Agnivirus</i> and the species <i>Agnivirus brisbanense</i>. Viruses in the family possess a linear dsDNA genome of about 108 kbp and encode modules for DNA replication and virion morphogenesis, such as those relating to the formation of an icosahedral capsid and a helical tail, characteristic of members of the class <i>Caudoviricetes</i>. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family <i>Apasviridae</i>, which is available at ictv.global/report/apasviridae.
