Oryzavirus is a genus of double-stranded RNA viruses in the order Reovirales and family Spinareoviridae. Member viruses infect plants and are transmitted by planthoppers. Diseases associated with this genus include: rice stunting, enations on veins of leaves and leaf sheaths, ragged leaves, and flower suppression. There are two species in this genus.{{cite web|title=Viral Zone|url=http://viralzone.expasy.org/all_by_species/616.html|accessdate=15 June 2015|publisher=ExPASy}}{{cite web |title=Virus Taxonomy: 2024 Release |url=https://ictv.global/taxonomy |publisher=International Committee on Taxonomy of Viruses |date= |access-date=22 April 2025}}
Structure
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. The virus exits the host cell by monopartite non-tubule guided viral movement. The virus is transmitted via a vector (delphacid planthoppers). Transmission routes are vector.
Taxonomy
The genus contains the following species:
- Oryzavirus echinochloae, Echinochloa ragged stunt virus
- Oryzavirus oryzae, Rice ragged stunt virus
