Bean Yellow Mosaic Virus
Bean yellow mosaic virus is a plant pathogenic virus in the genus ''Potyvirus'' and the virus family ''Potyviridae''. Like other members of the ''Potyvirus'' genus, it is a monopartite strand of positive-sense, single-stranded RNA surrounded by a capsid made for a single viral encoded protein. The virus is a filamentous particle that measures about 750 nm in length. This virus is transmitted by species of aphids and by mechanical inoculation. Geographic distribution and host range A mosaic disease, believed to be bean yellow mosaic virus, was first reported in the early 1900s infecting garden peas (''Pisum sativum'') in the Northeastern United States. The virus is currently believed to be distributed worldwide. In addition to peas, this virus is known to infect many other legumes (family Fabaceae) including green beans (''Phaseolus vulgaris''), peanuts (''Arachis hypogaea''), soybeans (''Glycine max''), Faba beans (''Vicia faba''), several species of clover (''Trifolium hyb ...

Potyvirus
''Potyvirus'' is a genus of positive-strand RNA viruses (named after its type species, potato virus Y, Potato virus Y (''Potyvirus yituberosi,'' PVY)'')'' in the family ''Potyviridae''. Plants serve as natural hosts. Like begomoviruses, members of this genus may cause significant losses in agricultural, pastoral, Horticulture industry, horticultural, and Ornamental plant, ornamental crops. More than 200 species of aphids spread potyviruses, and most are from the subfamily ''Aphidinae'' (genera ''Macrosiphum'' and ''Myzus''). The genus contains 190 species and potyviruses account for about thirty percent of all currently known plant viruses. Structure The virion is Viral envelope, non-enveloped with a flexuous and filamentous Capsid, nucleocapsid, 680 to 900 nanometers (nm) long and is 11–20 nm in diameter. The nucleocapsid contains around 2000 copies of the capsid protein. The symmetry of the nucleocapsid is helical with a pitch of 3.4-3.5 nm. Genome The genome ...

Vicia Sativa
''Vicia sativa'', known as the common vetch, garden vetch, tare or simply vetch, is a Nitrogen fixation, nitrogen-fixing legume, leguminous plant in the family Fabaceae. It is now naturalised throughout the world occurring on every continent, except Antarctica and the Arctic. The centre of diversity is thought to be the Fertile Crescent, although gold standard molecular confirmation is currently not available. Global common vetch cultivation is limited due to anti-nutritional compounds in the seed although it is grown in dryland agricultural zones in Australia, China and Ethiopia due to its drought tolerance and very low nutrient requirements compared to other legumes. In these agricultural zones common vetch is grown as a green manure, livestock fodder or Crop rotation, rotation crop. In cultivated grainfields, like Lentil, lentils, it is often considered a weed due to downgrading of harvested mixed grain, resulting in farmers receiving less financial returns.

Potyviridae
''Potyviridae'' is a family of positive-strand RNA viruses that encompasses more than 30% of known plant viruses, many of which are of great agricultural significance. The family contains 13 genera that contain 259 species. Structure Potyvirid virions are nonenveloped, flexuous filamentous, rod-shaped particles. The diameter is around 11–20 nm, with a length of 650–950 nm. Genome Genomes are linear and usually nonsegmented, around 8–12kb in length, consisting of positive-sense RNA, which is surrounded by a protein coat made up of a single viral encoded protein called a capsid. All induce the formation of virus inclusion bodies called cylindrical inclusions (‘pinwheels’) in their hosts. These consist of a single protein (about 70 Dalton (unit), kDa) made in their hosts from a single viral genome product. Member viruses encode large polypeptides that are cleaved into mature proteins. In 5'–3' order these proteins are * P1 (a serine protease): 83 kDa * H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
