Phaeovirus is a genus of viruses, in the family Phycodnaviridae . Algae serve as natural hosts. There are three species in this genus. [1] [2]
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species: [2]
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. [1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Phaeovirus | Icosahedral | T=169 | Enveloped | Linear | Monopartite |
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. [1]
