Biology:Cavemovirus
Cavemovirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: vein-clearing or banding mosaic.[1][2]
Taxonomy
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[2][3]
- Cavemovirus collusipomeae, Sweet potato collusive virus
- Cavemovirus deltaepiphylli, Epiphyllum virus 4
- Cavemovirus venamanihotis, Cassava vein mosaic virus
Structure
Viruses in Cavemovirus are non-enveloped, with icosahedral geometries, and T=7 symmetry. The diameter is around 50 nm. Genomes are circular and non-segmented. The genome codes for 5 proteins.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Cavemovirus | Icosahedral | T=7 | Non-enveloped | Circular | Monopartite |
Life cycle
Viral replication is nuclear/cytoplasmic. Replication follows the dsDNA (RT) replication model. dsDNA (RT) transcription is the method of transcription. The virus exits the host cell by nuclear pore export, and tubule-guided viral movement. Plants serve as the natural host. The virus is transmitted via a vector (aphid insects). Transmission routes are mechanical.[1]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Cavemovirus | Plants | None | Viral movement; mechanical inoculation | Viral movement | Nucleus | Cytoplasm | Mechanical inoculation: aphids |
