Quadriviridae is a family of double-stranded RNA viruses with a single genus Quadrivirus.[1] Fungi serve as natural hosts. There is currently only one species in this family: the type species Rosellinia necatrix quadrivirus 1.[2][3]
Structure
Viruses in the family Quadriviridae have a non-enveloped isometric capsid. The diameter is around 48 nm.
Genome
Family member genomes are linear and made of double stranded RNA. They are divided in to four segments which each code for a protein. The length of the different segments are between 3.5 to 5.0 kbp. The total genome is around 16.8 kbp.[2][3]
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Fungi serve as the natural host.[2][3]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Quadrivirus | Fungi | None | Unknown | Cytoplasmic exchange; hyphal anastomosis; sporogenesis | Unknown | Unknown | Cytoplasmic exchange; hyphal anastomosis; sporogenesis |
Taxonomy
The family Quadrivirdae has one genus Quadrivirus which contains the species:
- Rosellinia necatrix quadrivirus 1
