Phaeovirus is a genus of viruses, in the family Phycodnaviridae. Algae serve as natural hosts. There are three species in this genus.
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:
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.
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.
