Rice Ragged Stunt Virus
Rice ragged stunt virus (RRSV) is a plant pathogenic virus of the family ''Reoviridae ''Reoviridae'' is a family of double-stranded RNA viruses. Member viruses have a wide host range, including vertebrates, invertebrates, plants, protists and fungi. They lack lipid envelopes and package their segmented genome within multi-layere ...''. 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 about 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 eight 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 pla ...

Reoviridae
''Reoviridae'' is a family of double-stranded RNA viruses. Member viruses have a wide host range, including vertebrates, invertebrates, plants, protists and fungi. They lack lipid envelopes and package their segmented genome within multi-layered capsids. Lack of a lipid envelope has allowed three-dimensional structures of these large complex viruses (diameter ∼60–100 nm) to be obtained, revealing a structural and likely evolutionary relationship to the cystovirus family of bacteriophage. There are currently 97 species in this family, divided among 15 genera in two subfamilies. Reoviruses can affect the gastrointestinal system (such as rotaviruses) and respiratory tract. The name "reo-" is an acronym for "''r''espiratory ''e''nteric ''o''rphan" viruses''.'' The term " orphan virus" refers to the fact that some of these viruses have been observed not associated with any known disease. Even though viruses in the family ''Reoviridae'' have more recently been identified with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
