Prasinovirus is a genus of viruses, in the family Phycodnaviridae. Alga serve as natural hosts. There are currently only two species in this genus including the type species Micromonas pusilla virus SP1.[1][2]
Taxonomy
Group: dsDNA
Order: Unassigned
- Family: Phycodnaviridae
- Genus: Prasinovirus
Structure
Viruses in Prasinovirus are enveloped, with icosahedral and Round geometries, and T=169 symmetry. The diameter is around 104-118 nm.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Prasinovirus | 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 |
|---|---|---|---|---|---|---|---|
| Prasinovirus | Alga | None | Cell receptor endocytosis | Lysis | Nucleus | Cytoplasm | Passive diffusion |
