Fijivirus
''Fijivirus'' is a genus of double-stranded RNA viruses in the family ''Reoviridae'' and subfamily ''Spinareovirinae.'' Plants serve as natural hosts. Diseases associated with this genus include: galls (tumours) in infected plants and Fiji disease, with severe stunting, deformation and death. The group name derives from ''Fiji'' island the place where the first virus was isolated. There are nine species in this genus. Structure Fijivirus genome composition contains ten linear double-stranded RNA (dsRNA) and is carried within virus particles referred to as virions. The Fijivirus genome is constructed inside the virion and is non-enveloped. It contains two separate layers of capsids, an inner and an outer layer, which are constructed by proteins that shell the virus. The capsids are of icosahedral symmetry (T=2 for inner capsid, T=13 for outer capsid), and have an obvious round structure, which is on average 65–70 nm in diameter. Genomes are linear and segmented, around 4.5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiji Disease Virus
Fiji disease virus (FDV) belongs to the reoviridae family and infects plants. It is one of the few plant viruses in the Reoviridae family. The type species of the genus '' Fijivirus'', it is the only known member of Fijivirus group 1. Fiji disease virus is named after the country in which it was originally observed. The earliest recording of FDV is from 1886 in a commercial farming spread of infection. By 1906, FDV had spread throughout the islands in the Pacific Ocean, posing a major threat to the sugar industry in the region. A major outbreak occurred in the 1950s when two varieties of sugar cane were planted that presented a high susceptibility to the virus. Although it was not discovered in New Guinea until 1914, it is considered to be the original location of FDV. FDV was most likely present in much of the Oceania region including Australia and the Philippines before its discovery in 1886. Structure The virus is between 65-70 nm in diameter. FDV is not enveloped but h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spinareovirinae
''Spinareovirinae'' is a subfamily of double-stranded RNA viruses in the family ''Reoviridae''. 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 subfamily 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''.

Gramineae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, primaril ...
