Cytorhabdovirus is a genus of viruses in the family Rhabdoviridae,[1] order Mononegavirales. Plants serve as natural hosts.[2][3]
Taxonomy
The following genera are recognized:[4]
- Alfalfa dwarf cytorhabdovirus
- Barley yellow striate mosaic cytorhabdovirus
- Broccoli necrotic yellows cytorhabdovirus
- Cabbage cytorhabdovirus
- Colocasia bobone disease-associated cytorhabdovirus
- Festuca leaf streak cytorhabdovirus
- Lettuce necrotic yellows cytorhabdovirus
- Lettuce yellow mottle cytorhabdovirus
- Maize yellow striate cytorhabdovirus
- Maize-associated cytorhabdovirus
- Northern cereal mosaic cytorhabdovirus
- Papaya cytorhabdovirus
- Persimmon cytorhabdovirus
- Raspberry vein chlorosis cytorhabdovirus
- Rice stripe mosaic cytorhabdovirus
- Sonchus cytorhabdovirus 1
- Strawberry crinkle cytorhabdovirus
- Tomato yellow mottle-associated cytorhabdovirus
- Wheat American striate mosaic cytorhabdovirus
- Wuhan 4 insect cytorhabdovirus
- Wuhan 5 insect cytorhabdovirus
- Wuhan 6 insect cytorhabdovirus
- Yerba mate chlorosis-associated cytorhabdovirus
Structure
Cytorhabdovirions are enveloped, with bullet shaped and bacilliform geometries. These virions are about 75 nm wide and 180 nm long. Cytorhabdovirus genomes are linear, around 13 kb in length.[2][3]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Cytorhabdovirus | Bullet-shaped | Enveloped | Linear | Monopartite |
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the viral G glycoproteins to host receptors, which mediates endocytosis. Replication follows the negative stranded RNA virus replication model. Negative stranded rna virus transcription, using polymerase stuttering is the method of transcription. The virus exits the host cell by budding, and tubule-guided viral movement. Plants serve as the natural host. The virus is transmitted via a vector (insect aphid, leafhopper, planthopper, and insect). Transmission routes are vector.[2][3]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Cytorhabdovirus | Humans; cattle; rodents | None | Clathrin-mediated endocytosis; viral movement; mechanical inoculation | Budding; viral movement | Cytoplasm | Cytoplasm | Mechanical inoculation: aphid; mechanical inoculation: leafhopper; mechanical inoculation: planthopper |
