Tritimovirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There are six species in this genus.[1][2]
Taxonomy
[edit]The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[2][3]
- Tritimovirus arrhenatheri, Tall oatgrass mosaic virus
- Tritimovirus avenae, Oat necrotic mottle virus
- Tritimovirus bromi, Brome streak mosaic virus
- Tritimovirus eqlidense, Wheat Eqlid mosaic virus
- Tritimovirus triseti, Yellow oat-grass mosaic virus
- Tritimovirus tritici, Wheat streak mosaic virus
Structure
[edit]Viruses in Tritimovirus are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12-15 nm, with a length of 690-700 nm. Genomes are linear, monopartite or bipartite, and around 9.3-10.0kb in length.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Tritimovirus | Filamentous | Non-enveloped | Linear | Segmented |
Life cycle
[edit]Viral replication is cytoplasmic. 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 tubule-guided viral movement. Plants serve as the natural host. The virus is transmitted via a vector (mite). Transmission routes are vector and mechanical.[1]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Tritimovirus | Plants | None | Viral movement; mechanical inoculation | Viral movement | Cytoplasm | Cytoplasm | Mechanical inoculation: mites |
