Ilarvirus
''Ilarvirus'' is a genus of positive-strand RNA viruses in the family ''Bromoviridae''. Plants serve as natural hosts. There are 22 species in this genus. Structure Viruses in the genus ''Ilarvirus'' are non-enveloped, with icosahedral and quasi-spherical geometries, and T=3 symmetry. The diameter is around 29 nm. Genomes are linear and have three segments. Life cycle Viral replication is cytoplasmic and lysogenic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive-strand RNA virus replication model in the cytoplasm. Positive strand RNA virus transcription, using the internal initiation model of subgenomic RNA transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host. Transmission routes are mechanical inoculation by insects and plant to plant contact. Taxonomy The following species are assigned to the genus: * '' Ageratum latent virus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blueberry Shock Virus
''Blueberry shock virus'' (BlShV) is an ''Ilarvirus'' belonging to the '' Bromoviridae'' family. Schilder (2014), p. 1. The ''Bromoviridae'' family contains single-stranded, positive-sense RNA viruses. Virus particles are icosahedral and 30 nm in diameter. Gottula ''et al.'' (2012), p. 2. Blueberry shock virus causes shock of blueberries in Oregon, Washington, and British Columbia. It gets its name because plants are shocked by the initial infection, meaning the flowers and foliage blight and wilt in the early spring, right when the plant is in full bloom. BIShV was first discovered in a blueberry field containing highbush blueberry ('' Vaccinium corymbosum'' L.) in Washington in 1991. It continued to spread to Oregon, Washington and British Columbia since that time. In 2009, the disease was found in a western Michigan field, and may be preset in Pennsylvania as of 2011. Since its discovery, eradication is in progress to eliminate the disease and reduce loss of yield from it. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tobacco Streak Virus
Tobacco streak virus (TSV) is a plant pathogenic virus of the family ''Bromoviridae'', in the genus ''Ilarvirus''. It has a wide host range, with at least 200 susceptible species. TSV is generally more problematic in the tropics or warmer climates. TSV does not generally lead to epidemics, with the exception of sunflowers in India and Australia, and peanuts in India. Host and symptoms TSV has been reported worldwide in North and South America, Europe, India, Japan, Australia, New Zealand and South America. TSV has a wide host range including both monocots and dicots. Economically important crop hosts include peanuts, sunflower, soybean, cranberry, cotton, chickpea and mung beans. As with many plant viruses, diagnosis is very difficult because TSV has very wide host range and has different effects depending on the host being infected. Symptoms of TSV may include black streaks on stems and leaves, stunted growth, chlorosis, leaf mosaic, lodging, and deformed growing tips, to n ...

Prunus Necrotic Ringspot Virus
''Prunus necrotic ringspot virus'' (PNRSV) is a plant pathogenic virus causing ring spot diseases affecting species of the genus ''Prunus'', as well as other species such as rose (''Rosa'' spp.) and hops (''Humulus lupulus''). PNRSV is found worldwide due to easy transmission through plant propagation methods and infected seed. The virus is in the family '' Bromoviridae'' and genus ''Ilarvirus''. Synonyms of PNRSV include European plum line pattern virus, hop B virus, hop C virus, plum line pattern virus, sour cherry necrotic ringspot virus, and peach ringspot virus. Hosts and symptoms All cultivated species of the genus ''Prunus'', which includes plums, cherries, apricots, almonds, and peaches, are susceptible to one or more strains of PNRSV. Hops and rose are also susceptible to infection by the virus. Other susceptible hosts used for diagnosis include ''Chenopodium quinoa'' Willd., sunflower (''Helianthus annus''), and ''Momordica balsamina''. Symptoms on orchard trees can ...

Apple Mosaic Virus
Apple mosaic virus (ApMV) is a plant pathogenic virus of the family Bromoviridae. It is named after its symptoms that were first present on apples. ApMV is a positive sense RNA based virus. The disease itself has several synonyms including Mild Apple Mosaic Virus, Hop Virus, Rose Mosaic Virus, and European Plum Line Patten Virus. It causes a severe yield reduction and decreased life-expectancy of fruit trees. Hosts, transmission, and symptoms Host range ApMV has a diverse host range. These positive-sense single-stranded RNA viruses are capable of infecting over 65 species in 19 different families including different types of woody and herbaceous plants. This virus can infect either experimentally or naturally. Some of the natural hosts that are commonly targeted by ApMV include apples ''(Malus domestica)'', pears (''Pyrus communis)'', apricots (''Prunus armeniaca''), peach ''(Prunus persica)'', plum (''Prunus domestica''), strawberry (''Fragaria sp.)'', and hazelnut (''Coryl ...

Blackberry Chlorotic Ringspot Virus
The blackberry is an edible fruit produced by many species in the genus ''Rubus'' in the family Rosaceae, hybrids among these species within the subgenus ''Rubus'', and hybrids between the subgenera ''Rubus'' and ''Idaeobatus''. The taxonomy of blackberries has historically been confused because of hybridization and apomixis, so that species have often been grouped together and called species aggregates. For example, the entire subgenus ''Rubus'' has been called the '' Rubus fruticosus'' aggregate, although the species ''R. fruticosus'' is considered a synonym of '' R. plicatus''. '' Rubus armeniacus'' ("Himalayan" blackberry) is considered a noxious weed and invasive species in many regions of the Pacific Northwest of Canada and the United States, where it grows out of control in urban and suburban parks and woodlands. Description What distinguishes the blackberry from its raspberry relatives is whether or not the torus ( receptacle or stem) "picks with" (i.e., stays with) th ...
