Clerodendrum Thomsoniae
''Clerodendrum'' is a genus of flowering plants formerly placed in the family Verbenaceae, but now considered to belong to the Lamiaceae (mint) family. Its common names include glorybower, bagflower, pagoda flower and bleeding-heart. It is currently classified in the subfamily Ajugoideae, being one of several genera transferred from Verbenaceae to Lamiaceae in the 1990s, based on phylogenetic analysis of morphological and molecular data. The type species for the genus is '' Clerodendrum infortunatum''.''Clerodendrum'' In: Index Nominum Genericorum. In: Regnum Vegetabile (see ''External links'' below). It is native to Sri Lanka and the Andaman Islands.Anthony J. Huxley, Mark Griffiths, and Margot Levy (editors). 1992. ''The New Royal Horticultural Society Dictionary of Gardening.''

Botrytis Cinerea
''Botrytis cinerea'' is a necrotrophic fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as "botrytis bunch rot"; in horticulture, it is usually called "grey mould" or "gray mold". The fungus gives rise to two different kinds of infections on grapes. The first, grey rot, is the result of consistently wet or humid conditions, and typically results in the loss of the affected bunches. The second, noble rot, occurs when drier conditions follow wetter, and can result in distinctive sweet dessert wines, such as Sauternes, the Aszú of Tokaji, or Grasă de Cotnari. The species name ''Botrytis cinerea'' is derived from the Latin for "grapes like ashes"; although poetic, the "grapes" refers to the bunching of the fungal spores on their conidiophores, and "ashes" just refers to the greyish colour of the spores ''en masse''. The fungus is usually referred to by its anamorph (asexual form) name, because ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cercospora Apii F
''Cercospora'' is a genus of ascomycete fungi. Most species have no known sexual stage, and when the sexual stage is identified, it is in the genus '' Mycosphaerella''. Most species of this genus cause plant diseases, and form leaf spots. It is a relatively well-studied genus of fungi, but there are countless species not yet described, and there is still much to learn about the best-known members of the genus. It has a cosmopolitan distribution worldwide. Selected species The GBIF accepts 837 species (as of July 2023); See also List of Cercospora species *'' Cercospora acetosella'' - found on sheep sorrel and other docks *''Cercospora aciculina'' *'' Cercospora agerati'' *'' Cercospora alabemensis'' *'' Cercospora alismatis'' *'' Cercospora althaeina'' *'' Cercospora angreci'' - causes leaf spot of orchids *'' Cercospora angulata'' *'' Cercospora apii'' - causes leaf spot on celery, and found on other plants, including ''Impatiens'' * ''Cercospora apii'' f.sp.

Corynespora
''Corynespora'' is a fungus genus. It is a member of the mitosporic Ascomycota, a heterogeneous group of ascomycotic fungi whose common characteristic is the absence of a sexual state. Species in the genus induce Corynespora leaf spot in bleeding hearts (''Clerodendrum thomsoniae'').

Phyllosticta
''Phyllosticta'' is a genus of fungi. Many of the species in this genus are common and important plant pathogens. They typically infect the foliage and cause tannish-gray leaf spots with dark brown to purple borders. However, ''Phyllosticta'' may also infect fruit and stems. Yield loss is a common consequence of ''Phyllosticta'' infection. Representatives of the genus are found worldwide and on a wide range of plant hosts. History ''Phyllosticta'' was introduced by German mycologist Persoon in 1818 and species '' Phyllosticta convallariae'' was designated as the type species (Donk 1968). Since ''Phyllosticta'' is distinct from other genera in that family, Seaver (1922) treated it in the family ''Phyllostictaceae'' of the order Phyllostictites. Nevertheless, ''Phyllosticta'' was accommodated in the family ''Botryosphaeriaceae'' (in order Botryosphaeriales C.L. Schoch et al.) in several major studies (e.g. Crous et al. 2006; Schoch et al. 2006; Liu et al. 2012). However, the phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oidium (genus)
''Oidium'' is a genus of Deuteromycetes, where traditionally most anamorphs of the order Erysiphales are included. Most of them are plant pathogens causing different forms of powdery mildew, for example: *''Oidium alphitoides'' (= ''O. quercinum'') = '' Microsphaera alphitoides'' (on oaks) *'' Oidium anacardii'' (= ''Acrosporium anacardii'') (on cashew) *'' Oidium arachidis'' (on peanut) *''Oidium asteris-punicei'' (= ''Erysiphe cichoracearum'') (on mangos) *''Oidium balsamii'' = '' Erysiphe verbasci'' (on mulleins) *''Oidium begoniae'' (=''O.cyclaminis'', ''O.lini'', ''O.violae'') = '' Erysiphe polyphaga'' (on ''Valerianella'', ''Calluna'' and ''Erica'') *'' Oidium candicans'' (= ''Monilia candicans'') *'' Oidium caricae'' (on papayas) *'' Oidium caricae-papayae'' (on papayas) *'' Oidium caricicola'' (on papayas) *''Oidium chrysanthemi'' = ''Erysiphe cichoracearum'' (on numerous plant species, especially Asteraceae) *'' Oidium carpini'' *'' Oidium chartarum'' (= ''Torula chartar ...

Pythium
''Pythium'' is a genus of parasitic oomycetes. They were formerly classified as fungi. Most species are plant parasites, but '' Pythium insidiosum'' is an important pathogen of animals, causing pythiosis. The feet of the fungus gnat are frequently a vector for their transmission. Morphology ;Hyphae: ''Pythium'' species, like others in the family Pythiaceae, are usually characterized by their production of coenocytic hyphae without septations. ;Oogonia: Generally contain a single oospore. ;Antheridia: Contain an elongated and club-shaped antheridium. Ecological importance ''Pythium''-induced root rot is a common crop disease. When the organism kills newly emerged or emerging seedlings, it is known as damping off, and is a very common problem in fields and greenhouses. Thus there is tremendous interest in genetic host resistance, but no crop has ever developed adequate resistance to ''Pythium''. This disease complex usually involves other pathogens such as '' Phytopht ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meloidogyne Arenaria
''Meloidogyne arenaria'' is a species of plant pathogenic nematodes. This nematode is also known as the ''peanut root knot nematode''. The word "''Meloidogyne''" is derived from two Greek words that mean "apple-shaped" and "female".. The peanut root knot nematode, ''M. arenaria'' is one of the "major" ''Meloidogyne'' species because of its worldwide economic importance. ''M. arenaria'' is a predominant nematode species in the United States attacking peanut in Alabama, Florida, Georgia, and Texas. The most damaging nematode species for peanut in the USA is ''M. arenaria'' race 1 and losses can exceed 50% in severely infested fields.K. Proite, R. Carneiro R. Falcão, A. Gomes S. Leal-Bertioli P. Guimarães and D. Bertioli, 2008. Post-infection development and histopathology of Meloidogyne arenaria race 1 on Arachis spp. Among the several ''Meloidogyne'' species that have been characterized, ''M. arenaria'' is the most variable both morphologically and cytologically. In 1949, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meloidogyne Incognita
''Meloidogyne incognita'' (root-knot nematode, RKN), also known as the southern root-nematode or cotton root-knot nematode is a plant-parasitic roundworm in the family Heteroderidae. This nematode is one of the four most common species worldwide and has numerous hosts. It typically incites large, usually irregular galls on roots as a result of parasitism. ''M. incognita'' can move along shallower temperature gradients (0.001 °C/cm) than any other known organism, an example of thermotaxis. The response is complicated and thought to allow the nematodes to move toward an appropriate level in soil, while they search for chemical cues that can guide them to specific roots.Diez and Dusenbery. 1989. Repellent of root-knot nematodes from the exudate of host roots. Journal of Chemical Ecology. 15:2445-2455. Distribution ''Meloidogyne incognita'' is widely spread around the globe and found in many different soil types. Host ''Meloidogyne incognita'' is probably the most ec ...

Tospovirus
''Orthotospovirus'' is a genus of negative-strand RNA viruses, in the family ''Tospoviridae'' of the order '' Elliovirales,'' which infects plants. Tospoviruses take their name from the species Tomato spotted wilt virus (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 28 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 least ten species of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impatiens Necrotic Spot Virus
Impatiens necrotic spot virus (INSV) is a Plant Virus, plant pathogenic virus of the genus ''Orthotospovirus''. 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 (epidemiology), vector of the Frankliniella occidentalis, western flower thrips. The virus infects more than 648 species of plants including important horticulture, horticultural and agriculture, agricultural species such as fuchsia, tomato, orchids, and lettuce (especially romaine). As the name implies, the main symptom on plants is Necrosis, 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 of the plant. The disease is mainly co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tobamovirus
''Tobamovirus'' is a genus of positive-strand RNA viruses in the family ''Virgaviridae.'' Many plants, including tobacco, potato, tomato, and Squash (plant), squash, serve as natural hosts. Diseases associated with this genus include: necrotic lesions on leaves. The name ''Tobamovirus'' comes from the host and symptoms of the first virus discovered (Tobacco mosaic virus). There are four informal subgroups within this genus: these are the tobamoviruses that infect the brassicas, Cucurbitaceae, cucurbits, Malvaceae, malvaceous, and Solanaceae, solanaceous plants. The main differences between these groups are genome sequences, and respective range of host plants. There are 37 species in this genus. Structure Tobamoviruses are non-enveloped, with helical rod geometries, and helical symmetry. The diameter is around 18 nm, with a length of 300–310 nm. Genomes are linear and non-segmented, around 6.3–6.5kb in length. Genome The RNA genome encodes at least four polypept ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
