Cineraria
''Cineraria'' is a genus of flowering plants in the sunflower family, native primarily to southern Africa with a few species farther north. The genus includes herbaceous plants and small subshrubs. In the past, the genus was commonly viewed in a broader sense including a number of species from the Canary Islands and Madeira which are now transferred to the genus '' Pericallis'', including the florist's cineraria (''Pericallis × hybrida''). Species , Plants of the World Online accepts the following species: *'' Cineraria abyssinica'' Sch.Bip. ex A.Rich. *''Cineraria albicans'' N.E.Br. *'' Cineraria albomontana'' Hilliard *''Cineraria alchemilloides'' DC. *'' Cineraria anampoza'' (Baker) Baker *'' Cineraria arctotidea'' DC. *''Cineraria aspera'' Thunb. *''Cineraria atriplicifolia'' DC. *''Cineraria austrotransvaalensis'' Cron *''Cineraria britteniae'' Hutch. & R.A.Dyer *''Cineraria burkei'' Burtt Davy *''Cineraria canescens'' Wendl.Obs. ex Link *''Cineraria cyanomontana'' ...

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] |
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] |
Meloidogyne Javanica
''Meloidogyne javanica'' is a species of plant-pathogenic nematodes. It is one of the tropical root-knot nematodes and a major agricultural pest in many countries. It has many hosts. ''Meloidogyne javanica'' reproduces by obligatory mitotic parthenogenesis (apomixis). Hosts ''Meloidogyne javanica'' is a nematode pathogen that affects over 770 species of plants (Cabi 2018). The hosts of this pathogen include both weeds and crops of economic importance. Those of economic importance include tea, grapevine, vegetables, fruit trees, cereals, and ornamentals (Cabi 2018). ''Meloidogyne javanica'' is considered an agricultural pest, as it is extremely abundant and damaging (Alford 2012). Symptoms Because there are so many different hosts for this pathogen, the symptoms are very variable. Common symptoms include abnormal leaf color, abnormal leaf form, wilting leaves, galls, swollen roots, reduced root system, dwarfing and senescence (Cabi 2018). This pathogen does the most damage w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphelenchoides Ritzemabosi
''Aphelenchoides ritzemabosi'' (Black currant nematode, Chrysanthemum foliar nematode, Chrysanthemum leaf nematode, Chrysanthemum nematode, Chrysanthemum Foliar eelworm) is a plant pathogenic nematode. It was first scientifically described in 1890 in England. This nematode has a wide host range. Among the most important species affected are Chrysanthemums and strawberries. ''A. ritzemabosi'' is a migratory foliar feeding nematode. It can feed both ectoparasitically and endoparasitically, with the later causing the most significant damage. When adequate moisture is present, this nematode enters the leaves and feeds from inside the tissue. Typical damage is characterized by necrotic zones between the veins of the leaves. Its lifecycle is short; only ten days from egg to mature adult. A single female can lay as many as 3,500 eggs. This pest can be difficult to control. Host plant resistance, hot water treatments, and predatory mites are recommended. Nomenclature and Synon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhizoctonia Solani
''Rhizoctonia solani'' is a species of fungus in the order Cantharellales. Basidiocarps (fruit bodies) are thin, effused, and web-like, but the fungus is more typically encountered in its anamorphic state, as hyphae and sclerotia. The name ''Rhizoctonia solani'' is currently applied to a complex of related species that await further research. In its wide sense, ''Rhizoctonia solani'' is a facultative plant pathogen with a wide host range and worldwide distribution. It causes various plant diseases such as root rot, damping off, and wire stem. It can also form mycorrhizal associations with orchids. Taxonomy In 1858, the German plant pathologist Julius Kühn observed and described a fungus on diseased potato tubers and named it ''Rhizoctonia solani'', the species epithet referring to ''Solanum tuberosum'' (potato). The disease caused was well known before the discovery and description of the fungus. In 1956, Dutch mycologist M.A. Donk published the new name ''Thanatephorus cucumer ...

Pythium Ultimum
''Pythium ultimum'' is a plant pathogen. It causes the damping off and root rot diseases of hundreds of diverse plant hosts including corn, soybean, potato, wheat, fir, and many ornamental species. ''P. ultimum'' belongs to the peronosporalean lineage of oomycetes, along with other important plant pathogens such as ''Phytophthora'' spp. and many genera of downy mildews. ''P. ultimum'' is a frequent inhabitant of fields, freshwater ponds, and decomposing vegetation in most areas of the world. Contributing to the widespread distribution and persistence of ''P. ultimum'' is its ability to grow saprotrophically in soil and plant residue. This trait is also exhibited by most ''Pythium'' spp. but not by the related ''Phytophthora'' spp., which can only colonize living plant hosts. Pathology and disease management Infections of seeds and roots are initiated by both the mycelia and spores of ''P. ultimum''. Two spore types are made, depending on the strain. ''P. ultimum'' is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
