Anemone
''Anemone'' () is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are commonly called windflowers. They are native to the temperate and subtropical regions of all continents except Australia, New Zealand and Antarctica. The genus is closely related to several other genera including ''Anemonoides'', ''Anemonastrum'', ''Hepatica'', and ''Pulsatilla''. Some botanists include these genera within ''Anemone''. Description ''Anemone'' are perennials that have basal leaves with long leaf-stems that can be upright or prostrate. Leaves are simple or compound with lobed, parted, or undivided leaf blades. The leaf margins are toothed or entire. Flowers with 4–27 sepals are produced singly, in cymes of 2–9 flowers, or in umbels, above a cluster of leaf- or sepal-like bracts. Sepals may be any color. The pistils have one ovule. The flowers have nectaries, but petals are missing in the majority of species. The fruits are ovoid to obovoid shaped ...

Cucumber Mosaic Virus
''Cucumber mosaic virus'' (CMV) is a plant pathogenic virus in the family ''Bromoviridae''. This virus has a worldwide distribution and a very wide host range, having the reputation of the widest host range of any known plant virus. It can be transmitted from plant to plant both mechanically by sap and by aphids in a stylet-borne fashion. It can also be transmitted in seeds and by the parasitic weeds, ''Cuscuta sp.'' (dodder). Hosts and symptoms This virus was first characterized in cucumbers (''Cucumis sativus'') showing mosaic symptoms in 1934, hence the name ''Cucumber mosaic''. Since then, it has been found to infect a great variety of other plants. These include other vegetables such as squash, melons, peppers, eggplants,tomatoes, beans, carrots, celery, lettuce, spinach, beets, many ornamentals and bedding plants, such as '' Narcissus'', and various weeds. Its presence has been confirmed on every continent of the world, including Antarctica. Symptoms seen with this virus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potyvirus
''Potyvirus'' is a genus of positive-strand RNA viruses in the family ''Potyviridae''. Plants serve as natural hosts. The genus is named after member virus ''potato virus Y''. Potyviruses account for about thirty percent of the currently known plant viruses. Like begomoviruses, members of this genus may cause significant losses in agricultural, pastoral, horticultural, and 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. Virology Structure The virion is non-enveloped with a flexuous and filamentous 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 nm. Genome The genome is a linear, positive-sense, single-stranded RNA ranging in size from 9,000–12,000 nucleoti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tomato Spotted Wilt Virus
Transmission and lifespan TSWV, which is transmitted by thrips, causes serious losses in economically important crops and it is one of the most economically devastating plant viruses in the world. The circulative propagative transmission of TSWV is carried out by at least ten different species of thrips. The most common species is ''Frankliniella occidentalis'' (western flower thrips) as it is the vector that predominantly transmits TSWV globally and in greenhouses. The rapid developmental and reproductive rate of the thrips contributes to the spread of TSWV. The amount of time it takes for insects to acquire the virus (acquisition period) and the amount of time it takes for the virus to move from the insect to the plant (inoculation) for TSWV varies depends on the vector species. For ''Frankliniella occidentalis'', the acquisition and inoculation of TSWV can be as short as 5 minutes. However, the acquisition and inoculation periods for optimal transmission is 21.3 hours and 42 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tobacco Ringspot Virus
''Tobacco ringspot virus'' (TRSV) is a plant pathogenic virus in the plant virus family ''Secoviridae''. It is the type species of the genus ''Nepovirus''. Nepoviruses are transmitted between plants by nematodes, thrips, mites, grasshoppers, and flea beetles. TRSV is also easily transmitted by sap inoculation and transmission in seeds has been reported. In recent cases it has also been shown to appear in bees, but no transmission to plants from bees has been noted. TRSV was observed for the first time in tobacco fields in Virginia and described in 1927. It is an isometric particle with a bipartite RNA genome. The virus has a wide host range that includes field grown crops, ornamentals and weeds. Its name comes from its most common symptom being chlorotic ringspots on the leaves of infected plants. In some areas this virus has caused growers to stop growing affected crops. A. B. C. Symptoms and virus inclusions of Tobacco ringspot nepovirus in the host ''Zamia furfuracea'', th ...

Tobacco Necrosis Virus
''Tobacco necrosis virus A'' is a plant pathogenic virus of the family ''Tombusviridae''. Hosts and symptoms Tobacco necrosis virus (TNV) can thrive on a handful of viable hosts. These hosts include tobacco, zucchini, cucumbers, carrots, French bean, tomatoes, potatoes, and tulips. There are a variety of symptoms that are dependent on the host species. In infected plants, abnormal coloring or necrotic tissue in the leaves may occur and roots may have lesions. If bark is present on the plant, it may become discolored. Fruit or tubers can become covered with sunken and discolored spots and can be smaller overall. On a whole-plant scale, damping off or early dying may occur. Management Currently, there is not a way to chemically control tobacco necrosis virus. There are, however, cultural management options to reduce the risk of the virus. Prior to planting, one can reduce risk of this disease by investigating the history of their soil for past presence of TNV or of its fungal ho ...

Impatiens Necrotic Spot Virus
''Impatiens necrotic spot orthotospovirus'' (INSV) is a plant pathogenic virus of the order ''Bunyavirales''. It was originally believed to be another strain of ''Tomato spotted wilt virus,'' but genetic investigations revealed them to be separate viruses. It is a negative-strand RNA virus which has a tripartite genome. It is largely spread by the insect vector of the western flower thrips. The virus infects more than 648 species of plants including important horticultural and agricultural species such as fuchsia, tomato, orchids, and lettuce (especially romaine). As the name implies, the main symptom on plants is necrotic spots that appear on the leaves. The INSV virus infects by injecting the RNA the virus contains into the cell which then starts using the cell resources to transcribe what the virus RNA states. Viral infection can often result in the death Death is the irreversible cessation of all biological functions that sustain an organism. For organisms with a bra ...

Tospovirus
''Orthotospovirus'' is a genus of negative-strand RNA viruses, in the family ''Tospoviridae'' of the order ''Bunyavirales,'' which infects plants. Tospoviruses take their name from the species '' Tomato spotted wilt orthotospovirus'' (TSWV) which was discovered in Australia in 1919. TSWV remained the only known member of the family until the early 1990s when genetic characterisation of plant viruses became more common. There are now at least twenty species in the genus with more being discovered on a regular basis. Member viruses infect over eight hundred plant species from 82 different families. Genome Tospoviruses have a negative-sense, single-strand RNA genome. The genome resembles that of the genus ''Phlebovirus''. It is linear and is 17.2 kb in size. It is divided into three segments termed S (2.9kb), M (5.4kb), and L (8.9kb). The M and S RNA segments encode for proteins in an ambisense direction. Transmission Tospoviruses are arboviruses usually vectored by thrips. At ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cucumovirus
''Cucumovirus'' is a genus of viruses, in the family ''Bromoviridae''. Plants serve as natural hosts. There are four species in this genus. Taxonomy The following species are assigned to the genus: * ''Cucumber mosaic virus'' * '' Gayfeather mild mottle virus'' * '' Peanut stunt virus'' * ''Tomato aspermy virus'' Structure Viruses in the genus ''Cucumovirus'' are non-enveloped, with icosahedral and Spherical geometries, and T=3 symmetry.
