Fungal Plant Pathogens And Diseases
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. More recently varietal diversific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoma
''Phoma'' is a genus of common coelomycetous soil fungi. It contains many plant pathogenic species. Description Spores are colorless and unicellular. The pycnidia are black and depressed in the tissues of the host. ''Phoma'' is arbitrarily limited to those species in which the spores are less than 15 µm as the larger spored forms have been placed in the genus '' Macrophoma''. The most important species include '' Phoma beta'' which is the cause of the heart rot and blight of beets, '' Phoma batata'' that produces a dry rot of sweet potato, and '' Phoma solani''. Taxonomy About 140 ''Phoma'' taxa have been defined and recognized which may be divided into two large groups: (i) plurivorous fungi, generally saprobic or weakly parasitic, mainly from temperate regions in Eurasia, but occasionally also found in other parts of the world (including areas with cool or warm climates); and (ii) specific pathogens of cultivated plants. However other estimates place the number of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
