Foveavirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants serve as natural hosts. There are eight species in this genus. Diseases associated with this genus include: mosaic and ringspot symptoms.[1][2]
Taxonomy
The following species are assigned to the genus:[2]
- Apple stem pitting virus
- Apricot latent virus
- Asian prunus virus 1
- Asian prunus virus 2
- Grapevine rupestris stem pitting-associated virus
- Grapevine virus T
- Peach chlorotic mottle virus
- Rubus canadensis virus 1
Structure
Viruses in Foveavirus are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12-13 nm. Genomes are linear, around 8.4-9.3kb in length. The genome codes for 5 proteins.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Foveavirus | Filamentous | Non-enveloped | Linear | Monopartite |
Life cycle
Viral replication is cytoplasmic, and is lysogenic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by tripartite non-tubule guided viral movement. Plants serve as the natural host. Transmission routes are grafting.[1]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Foveavirus | Plants | None | Viral movement; mechanical inoculation | Viral movement | Cytoplasm | Cytoplasm | Grafting |
