Abstract

The family Aoguangviridae includes dsDNA viruses that have been associated with marine archaea. Currently, members of this virus family are known through metagenomics. Virions are predicted to consist of an icosahedral capsid and a helical tail, characteristic of members in the class Caudoviricetes. Aoguangviruses have some of the largest genomes among archaeal viruses and possess most of the components of the DNA replication machinery as well as auxiliary functions. The family Aoguangviridae includes the species Aobingvirus yangshanense. Many unclassified relatives of this virus group, referred to as 'magroviruses', have been discovered by metagenomics in globally distributed marine samples. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Aoguangviridae, which is available at ictv.global/report/aoguangviridae.

Keywords: ICTV Report; Magrovirales; archaeal Caudoviricetes; magroviruses; marine archaea; virus taxonomy.
