Prymnesiovirus is a genus of viruses, in the family Phycodnaviridae. Alga serve as natural hosts. There is currently only one species in this genus: the type species Chrysochromulina brevifilum virus PW1.[1][2]
Taxonomy
Group: dsDNA
Order: Unassigned
- Family: Phycodnaviridae
- Genus: Prymnesiovirus
- Chrysochromulina brevifilum virus PW1
Structure
Viruses in Prymnesiovirus are enveloped, with icosahedral and round geometries, and T=169 symmetry. The diameter is around 100-170 nm. Genomes are linear, around 120-485kb in length.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Prymnesiovirus | Icosahedral | T=169 | Enveloped | Linear | Monopartite |
Life cycle
Viral replication is nucleo-cytoplasmic. 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]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Prymnesiovirus | Alga | None | Cell receptor endocytosis | Lysis | Nucleus | Cytoplasm | Passive diffusion |
