Solendovirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There are two species in this genus. Diseases associated with this genus include: TVCV: vein-clearing symptoms in N. edwardsonii.[1][2]
Taxonomy
The genus contains the following species:[2]
- Sweet potato vein clearing virus
- Tobacco vein clearing virus
Structure
Viruses in Solendovirus are non-enveloped, with icosahedral geometries, and T=7 symmetry. The diameter is around 50 nm. Genomes are circular and non-segmented, around 7.7kb in length. The genome has 3 open reading frames.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Solendovirus | 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. Transmission routes are seed borne.[1]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Solendovirus | Plants | None | Viral movement; mechanical inoculation | Viral movement | Nucleus | Cytoplasm | Seeds |
