Benyvirus is a genus ofviruses, in the familyBenyviridae.[1][2] Plants serve as natural hosts. There are four species in this genus. Diseases associated with this genus include: BNYVV: rhizomania.[2][3][4]
The genus contains the following species, listed with their scientific name and common name:[5]
Viruses in the genusBenyvirus 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]

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]
