Phaeovirus is a genus of viruses, in the family Phycodnaviridae. Alga serve as natural hosts. There are currently nine species in this genus including the type species Ectocarpus siliculosus virus 1.
Group: dsDNA
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.
