Rice ragged stunt virus

Rice ragged stunt virus (RRSV) is a plant pathogenic virus of the family Reoviridae.

Family: Reoviridae Genus: Oryzavirus Species: Rice ragged stunt virus Acronym: RRSV

Rice ragged stunt virus (RRSV), vectored by the brown planthopper (BPH) (Delphacidae: Nilaparvata lugens), causes ragged stunt disease of rice (Oryza spp., especially Oryza sativa). The virus, first described by Hibino, Ling and Shikata, is also less commonly known as rice infectious gall virus. RRSV has polyhedral particles c. 50 nm in diameter possessing spikes (and perhaps a complete outer shell) to a diameter of 65 nm. The particles contain double-stranded RNA in 8 segments. RRSV can only infect plants in the family Gramineae, i.e. grasses including rice. The virus can only be transmitted by BPH and is not mechanically transmitted to plants.
