Rice Tungro Bacilliform Virus
Rice is the seed of the grass species '' Oryza sativa'' (Asian rice) or less commonly ''Oryza glaberrima'' (African rice). The name wild rice is usually used for species of the genera ''Zizania'' and ''Porteresia'', both wild and domesticated, although the term may also be used for primitive or uncultivated varieties of ''Oryza''. As a cereal grain, domesticated rice is the most widely consumed staple food for over half of the world's human population,Abstract, "Rice feeds more than half the world's population." especially in Asia and Africa. It is the agricultural commodity with the third-highest worldwide production, after sugarcane and maize. Since sizable portions of sugarcane and maize crops are used for purposes other than human consumption, rice is the most important food crop with regard to human nutrition and caloric intake, providing more than one-fifth of the calories consumed worldwide by humans. There are many varieties of rice and culinary preferences tend to vary ...

International Committee On Taxonomy Of Viruses
The International Committee on Taxonomy of Viruses (ICTV) authorizes and organizes the taxonomic classification of and the nomenclatures for viruses. The ICTV has developed a universal taxonomic scheme for viruses, and thus has the means to appropriately describe, name, and classify every virus that affects living organisms. The members of the International Committee on Taxonomy of Viruses are considered expert virologists. The ICTV was formed from and is governed by the Virology Division of the International Union of Microbiological Societies. Detailed work, such as delimiting the boundaries of species within a family, typically is performed by study groups of experts in the families. History The International Committee on Nomenclature of Viruses (ICNV) was established in 1966, at the International Congress for Microbiology in Moscow, to standardize the naming of viruses. The ICVN published its first report in 1971. For viruses infecting vertebrates, the first report includ ...

Secoviridae
''Secoviridae'' is a family of viruses in the order '' Picornavirales''. Plants serve as natural hosts. There are 8 genera and 86 species in this family, one of which is unassigned to a genus. The family was created in 2009 with the grouping of families ''Sequiviridae'', now dissolved, and ''Comoviridae'', now subfamily ''Comovirinae'', along with the then unassigned genera ''Cheravirus'', ''Sadwavirus'', and ''Torradovirus''. Taxonomy The family includes the following genera (-''virinae'' denotes subfamily and -''virus'' denotes genus): * '' Comovirinae'' ** '' Comovirus'' ** '' Fabavirus'' ** '' Nepovirus'' * Unassigned to a subfamily: ** '' Cheravirus'' ** '' Sadwavirus'' ** '' Sequivirus'' ** '' Torradovirus'' ** '' Waikavirus'' Lastly, one species is unassigned to a genus: ''Strawberry latent ringspot virus Strawberry latent ringspot virus (SLRSV) is a plant pathogenic virus in an Unassigned family. Its entry in the ICTV database indicates this virus is a Sadwavirus bu ...
