Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Fungal Plant Pathogens And Diseases
A fungus (: fungi , , , or ; 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 one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 fungi'' or ' ...

Wheat Diseases
The cereal grain wheat is subject to numerous wheat diseases, including bacterial, viral and fungal diseases, as well as parasitic infestations. Principal diseases * Barley yellow dwarf virus, BYDV * Brown rust '' Puccinia recondita'' * Common bunt (aka Covered smut) '' Tilletia caries'' * Ergot '' Claviceps purpurea'' * Eyespot '' Pseudocercosporella herpotrichoides'' * Glume blotch '' Septoria nodorum'' * septoria leaf blotch ''Mycosphaerella graminicola'', synonyms: ''Septoria tritici'', ''Zymoseptoria tritici'' * Mildew '' Erysiphe graminis'' * Seedling blight ''Fusarium'' spp., ''Septoria nodorum'' * Sharp eyespot '' Rhizoctonia cerealis'' * Spot blotch '' Biplolaris sorokiana'' * Take-all '' Gaeumannomyces graminis'' * Tan spot '' Pyrenophora tritici-repentis'' * Yellow rust '' Puccinia striiformis'' In Europe Cereals are at risk from numerous diseases due to the level of intensification necessary for profitable production since the 1970s.

Dothideales
Dothideales are an order (biology), order of bitunicate fungi consisting mainly of saprobic or plant parasitic species. Description Taxa in this order are characterized by the absence of a hamathecium (defined as hyphae or other tissues between ascus, asci) in a locule, and formation of ovoid to cylindrical fisstunicate asci (asci that have two wall layers that split at maturity in a Jack-in-the-box-like fashion), usually in bundles or cluster called fascicles. During development, the asci push through the stromatic tissue, creating the locules. Classification Until 2001, this order was thought to contain five families: ''Botryosphaeriaceae'', ''Coccoidiaceae'', ''Doditheaceae'', ''Dothioraceae'', and the ''Planistromellaceae''. Several molecular phylogenetic studies since that time have resulted in an organization restructuring of classification. In the December 31, 2007 revision of Ascomycota classification the Dothideales contains two families, the ''Dothidiaceae'' and th ...

Fungi Described In 1849

Taxa Named By Elias Magnus Fries
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
