Phaeovirus is a genus of viruses, in the family Phycodnaviridae. Algae serve as natural hosts. There are three species in this genus.{{cite web|title=Viral Zone|url=http://viralzone.expasy.org/all_by_species/590.html|publisher=ExPASy|accessdate=15 June 2015}}{{cite web|title=Virus Taxonomy: 2024 Release|url=https://ictv.global/taxonomy|publisher=International Committee on Taxonomy of Viruses|access-date=23 March 2025}}
Taxonomy
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:
- Phaeovirus feldmanniae, Ectocarpus siliculosus virus 1
- Phaeovirus irregularis, Feldmannia irregularis virus a
- Phaeovirus unasiliculosus, Feldmannia species virus
Structure
File:Phycodnaviridae virion.jpg
Viruses in Phaeovirus are enveloped, with icosahedral and round geometries, and T=169 symmetry. The diameter is around 120-150 nm. Genomes are linear, around 150-350kb in length.

Life cycle
Viral replication is nucleo-cytoplasmic, and is lysogenic. Replication follows the DNA strand displacement model. DNA-templated transcription is the method of transcription. The virus exits the host cell by lysis via lytic phospholipids. Alga serve as the natural host. Transmission routes are passive diffusion.
