Bean Pod Mottle Virus
''Bean pod mottle virus'', or BPMV, is a species of plant pathogenic virus in the family ''Secoviridae''. It is known to infect soybean crops. Description BPMV is the viral pathogen that causes the disease Bean Pod Mottle in soybeans and other legumes such as snap peas. BPMV is a species in the plant pathogenic virus family ''Comoviridae'', and genus ''Comovirus'' characterized by icosahedral symmetry, non-enveloped, having two single stranded positive-sense RNAs (RNA-1 and RNA-2) separately encapsulated in isomeric particles, and are between 28 and 30 nm in diameter. (Bradshaw, 2007). The virus can overwinter in leaf-feeding beetle vectors (such as the bean leaf beetle), survive in perennial host species, and in virus-infected seed. In the North Central Region, the bean leaf beetle ('' Cerotoma trifurcate)'' is the most influential vector, by feeding on infected legumes and transferring virus particles to the next plant it lands on to feed. The BPMV disease has most signi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Broad Bean Stain Virus
Broad bean stain virus (BBSV) is a plant pathogenic virus of the family '' Comoviridae''. It infects species in the Fabaceae family of flowering legumes and is not restricted to only broad beans despite its name. The virus is transmitted through seeds and also plant weevils, such as '' Apion vorax''. It is a positive-sense single stranded RNA virus. Infections were first reported in the UK in 1965, with cases since reported throughout Europe, northern Africa, Australia, and Asia. Infected broad bean plants exhibit mottling and the seeds of infected plants can display a necrotic pattern on the seed coat. Studies by pest management plant biologists have seen success in trials that assessed titanium dioxide nanoparticles Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in ... as a way o ...

Broad Bean True Mosaic Virus
''Broad bean true mosaic virus'' (also called Echtes Ackerbohnemosaik-virus, ''Vicia'' virus 1, and ''Viciavirus varians'') is a virus first described in 1953 that affects legumes, commonly found in crops of broad bean ''Vicia faba'', commonly known as the broad bean, fava bean, or faba bean, is a species of vetch, a flowering plant in the pea and bean family Fabaceae. It is widely cultivated as a crop for human consumption, and also as a cover crop. Varieti ... in both Europe and Northwest Africa. There are no known vectors, although it has been known to transverse long distances between crops. Infection via seed is common, though the virus is also present in sap.

Cowpea Mosaic Virus
Cowpea mosaic virus (CPMV) is a non-enveloped plant virus of the Comovirinae, comovirus group. Infection of a susceptible cowpea leaf causes a "mosaic" Mosaic virus, pattern in the leaf, and results in high virus yields (1-2 g/kg). Its genome consists of 2 molecules of Sense (molecular biology), positive-sense RNA (RNA-1 and RNA-2) which are separately encapsidated. Both RNA1 and RNA2 have a VPg (virus genome-linked protein) at the 5'end, and polyadenylation at the 3' end. Genomic RNA1 and RNA2 are expressed by a polyprotein processing strategy. RNA1 encodes helicase, VPg, protease and RNA-dependent RNA polymerase, RdRp. RNA2 encodes Movement proteins, movement protein and Capsid, coat protein. The virus particles are 28 nm in diameter and contain 60 copies each of a Large (L) and Small (S) coat protein. The structure is well characterised to atomic resolution, and the viral particles are thermostable. The identification of the virus is attributed to Lister and Thresh in 19 ...

Squash Mosaic Virus
''Squash mosaic virus'' (SqMV) is a mosaic virus disease common in squash plants and other plants, including melons, of the family Cucurbitaceae. It occurs worldwide. It is transmitted primarily by beetles, including the leaf beetle ('' Acalymma trivittata''), spotted cucumber beetle (''Diabrotica undecimpunctata''), and 28-spotted ladybird beetle ('' Henosepilachna vigintioctopunctata''), as well as some other beetles. Plants are infected by the saliva expelled by the beetles as they feed upon the plant. The beetles acquire the virus by feeding upon an infected plant and can retain the virus in their bodies for up to 20 days. Unlike some other mosaic viruses that infect squashes, SqMV is not spread by aphids. In melons it can be spread by seeds. The results are dark green mosaic, blistering, vein clearing, yellowing of leaves, and hardening. Symptoms include "pronounced chlorotic mottle, green veinbanding, and distortion of leaves". Fruits of infected plants are also affected, bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Viruses
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898,Dimmock p. 4 more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or ''virions'', consisting of (i) the genetic material, i.e ...

Ullucus Virus C
''Ullucus'' is a genus of flowering plants in the family Basellaceae, with one species, ''Ullucus tuberosus'', a plant grown primarily as a root vegetable, secondarily as a leaf vegetable. The name ''ulluco'' is derived from the Quechua word , but depending on the region, it has many different names. These include ''illaco'' (in Aymara), ''melloco'' (in Ecuador), ''chungua'' or ''ruba'' (in Colombia), ''olluco'' or ''papa'' ''lisa'' (in Bolivia and Peru), or ''ulluma'' (in Argentina).Busch, J. and Savage, G.P.
