Benyvirus
Genus of viruses
From Wikipedia, the free encyclopedia
Benyvirus is a genus of viruses, in the family Benyviridae.[1][2] Plants serve as natural hosts. There are five species in this genus. Diseases associated with this genus include: BNYVV: rhizomania.[2][3][4]

Taxonomy
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[5][6]
- Benyvirus arctii, Burdock mottle virus
- Benyvirus necrobetae, Beet necrotic yellow vein virus
- Benyvirus oryzae, Rice stripe necrosis virus, isolates of which are known as RSNV; a rod-shaped virus containing just six open reading frames in its genome. A pathogen of rice plants, it may cause chlorosis, necrosis, and malformation.[7]
- Benyvirus solibetae, Beet soil-borne mosaic virus
- Benyvirus tritici, Wheat stripe mosaic virus
Structure
Viruses in the genus Benyvirus are non-enveloped, with rod-shaped geometries. The diameter is around 20 nm, with a length of 85–390 nm. Genomes are linear and segmented, around 6.7kb in length.[2][3]

Life cycle
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 tripartite non-tubule guided viral movement. Plant serve as the natural host. The virus is transmitted via a vector (protozoan). Transmission routes are vector.[2][3]
