Abstract

Members of the family Pleolipoviridae are pseudo-spherical and pleomorphic archaeal viruses composed of a membrane vesicle, which encloses a DNA genome. The genome is either circular ssDNA or dsDNA, or linear dsDNA molecules of approximately 7 to 17 kilonucleotides or kbp. Typically, virions contain a single type of transmembrane spike protein at the envelope and a single type of membrane protein, which is embedded in the envelope and located in the internal side of the membrane. All viruses infect extremely halophilic archaea in the class Halobacteria (phylum Euryarchaeota). Pleolipoviruses have a narrow host range and a persistent, non-lytic life cycle. Some viruses are temperate and can integrate into the host chromosome. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Pleolipoviridae, which is available at ictv.global/report/pleolipoviridae.
