es, in the family ''Benyviridae''. Plants serve as natural hosts. There are four species in this genus. Diseases associated with this genus include: BNYVV: rhizomania.

Taxonomy

The genus contains the following species, listed with their scientific name and common name: * ''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. * ''Benyvirus solibetae'', Beet soil-borne 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.

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.
