Rice Ragged Stunt Virus
Rice ragged stunt virus (RRSV) is a plant pathogenic virus of the family '' Spinareoviridae''. 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 ten segments. RRSV can only infect plants in the family Poaceae, i.e. grasses including rice. The virus can only be transmitted by BPH and is not mechanically transmitted to plants. Rice plants infected with RRSV are stunted with whitish spindle-shaped outgrowths. Later the infected leaves become twisted with ragged edges, and may eventually turn brown. Rice plants may survive the infection, but yields are greatly reduced du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinareoviridae
''Spinareoviridae'' is a family of double-stranded RNA viruses in the order ''Reovirales''. Viruses in this group are distinguished by the presence of a turreted protein on the inner capsid. (''Spina'' = spiny or thorny in Latin.) Taxonomy The family has nine genera: * '' Aquareovirus'' * '' Coltivirus'' * ''Cypovirus'' * '' Dinovernavirus'' * '' Fijivirus'' * '' Idnoreovirus'' * '' Mycoreovirus'' * ''Orthoreovirus ''Orthoreovirus'' is a genus of viruses, in the family ''Reoviridae'', in the subfamily ''Spinareovirinae''. Vertebrates serve as natural hosts. There are ten species in this genus.

Viral Plant Pathogens And Diseases
The word ''Viral'' means "relating to viruses" (small infectious agents). It may also refer to: Viral behavior, or virality Memetic behavior likened that of a virus, for example: * Viral marketing, the use of existing social networks to spread a marketing message * Viral phenomenon, relating to contagion theory or the "virality" of network culture, such as a meme * Viral video Viral videos are video, videos that become popular through viral phenomenon, a viral process of Internet sharing, primarily through video sharing websites such as YouTube as well as social media and email.Lu Jiang, Yajie Miao, Yi Yang, ZhenZhon ..., a video that quickly attains a high popularity Titled works * Viral (2016 American film), ''Viral'' (2016 American film), a 2016 American science fiction horror drama * Viral (2016 Hindi film), ''Viral'' (2016 Hindi film), an Indian Bollywood film based on social media * Viral (upcoming film), ''Viral'' (upcoming film), an American psychological thri ...

Reoviruses
''Sedoreoviridae'' (''sedo'' = smooth) is a family of the ''Reovirales'' order of viruses. Viruses in this family are distinguished by the absence of a turreted protein on the inner capsid to produce a smooth surface. Taxonomy The family contains the following genera: * '' Cardoreovirus'' * '' Crabreovirus'' * '' Mimoreovirus'' * '' Orbivirus'' * ''Phytoreovirus'' * ''Rotavirus'' * '' Seadornavirus'' Characteristics Like other members of the ''Reovirales'' order, viruses of the ''Sedoreoviridae'' family are made of naked, icosahedral capsids containing 10-12 segments of linear double-stranded RNA (dsRNA). The Baltimore System of viral classification categorizes ''Reovirales'' in Group III. Importance Viruses classified in the ''Sedoreoviridae'' family infect a wide range of plants and animals, including some that can infect humans. There is not only the potential of a few of these viruses to cause human disease, but also to reduce the supply of crops and livestock. Viruses Ge ...
