Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomyce ...

Sordariomycetes
Sordariomycetes is a class of fungi in the subdivision Pezizomycotina (Ascomycota), consisting of 28 orders, 90 families, 1344 genera. Sordariomycetes is from the Latin sordes (filth) because some species grow in animal feces, though growth habits vary widely across the class. Sordariomycetes generally produce their asci in perithecial fruiting bodies. Sordariomycetes are also known as Pyrenomycetes, from the Greek πυρἠν - 'the stone of a fruit' - because of the usually somewhat tough texture of their tissue. Sordariomycetes possess great variability in morphology, growth form, and habitat. Most have perithecial (flask-shaped) fruiting bodies, but ascomata can be less frequently cleistothecial (like in the genera '' Anixiella'', ''Apodus'', '' Boothiella'', ''Thielavia'', '' Zopfiella''),. Fruiting bodies may be solitary or gregarious, superficial, or immersed within stromata or tissues of the substrates and can be light to bright or black. Members of this group can grow ...

Diaporthales
Diaporthales is an order of sac fungi. Wijayawardene et al. in 2020 added a number of name families to the order. Diaporthales includes a number of plant pathogenic fungi, the most notorious of which is ''Cryphonectria parasitica'' (Murrill) Barr, the chestnut blight fungus that altered the landscape of eastern North America. Other diseases caused by members of this order include stem canker of soybeans ('' Diaporthe phaseolorum'' (Cooke & Ellis) Sacc. and its varieties), stem-end rot of citrus fruits ('' Diaporthe citri'' F.A. Wolf), and peach canker disease (''Phomopsis amygdali'' Del.). Some species produce secondary metabolites that result in toxicosis of animals such as lupinosis of sheep (''Diaporthe toxica'' P.M. Williamson et al.). A number of asexually reproducing plant pathogenic fungi also belong in the Diaporthales, such ''Greeneria uvicola'' (Berk. & Curt.) Punith., cause of bitter rot of grape, and ''Discula destructiva'' Redlin, cause of dogwood anthracnose, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Cytospora'' is a genus of ascomycete fungi. The genus was first described in 1818 by Christian Gottfried Ehrenberg.Ehrenberg, C.G.

Plant Pathogen
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canker
A plant canker is a small area of dead tissue, which grows slowly, often over years. Some cankers are of only minor consequence, but others are ultimately lethal and therefore can have major economic implications for agriculture and horticulture. Their causes include a wide range of organisms as fungi, bacteria, mycoplasmas and viruses. The majority of canker-causing organisms are bound to a unique host species or genus, but a few will attack other plants. Weather and animals can spread canker, thereby endangering areas that have only slight amount of canker. Although fungicides or bactericides can treat some cankers, often the only available treatment is to destroy the infected plant to contain the disease. Examples * Apple canker, caused by the fungus ''Neonectria galligena'' * Ash bacterial canker, now understood to be caused by the bacterium '' Pseudomonas savastanoi'', rather than ''Pseudomonas syringae''. After DNA-relatedness studies ''Pseudomonas savastanoi'' has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platanus
''Platanus'' is a genus consisting of a small number of tree species native to the Northern Hemisphere. They are the sole living members of the family Platanaceae. All mature members of ''Platanus'' are tall, reaching in height. All except for '' P. kerrii'' are deciduous, and most are found in riparian or other wetland habitats in the wild, though proving drought-tolerant in cultivation. The hybrid London plane (''Platanus ''×'' acerifolia'') has proved particularly tolerant of urban conditions, and has been widely planted in London and elsewhere in the United Kingdom. They are often known in English as ''planes'' or ''plane trees''. A formerly used name that is now rare is ''plantain tree'' (not to be confused with other, unrelated, species with the name). Some North American species are called ''sycamores'' (especially ''Platanus occidentalis''), although the term is also used for several unrelated species of trees. The genus name ''Platanus'' comes from Ancient Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
