Magnaporthaceae
The Magnaporthaceae are a family of fungi in the order Magnaporthales. It was circumscribed by Paul F. Cannon in 1994 for a group of grass-associated fungi centered on ''Magnaporthe'' (''Nakataea''). Magnaporthaceae have a harpophora-like asexual morphology and are often associated with roots of grasses or cereals. Important pathogens from the ''Magnaporthaceae'' include '' Nakataea oryzae, Gaeumannomyces graminis'', '' Magnaporthiopsis poae'' and ''Magnaporthe rhizophila''. Taxonomy and systematics Type genus: ''Nakataea'' Hara (= ''Magnaporthe'' R.A. Krause & R.K. Webster) Type species: '' Nakataea oryzae'' (Catt.) J. Luo & N. Zhang Description Magnaporthaceae that reproduce sexually, have perithecial ascomata that are immersed in host tissue, frequently with long necks. Asci are cylindrical and stain positive in Meltzer's reagent. Ascospores are curved to sigmoid and contain septa. They show variability in their morphology and can be filiform (''Gaeumannomyces'') or fus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyriculariaceae
The Pyriculariaceae are a family of ascomycete fungi in the order Magnaporthales. It was introduced by S. Klaubauf, M.H. Lebrun & P.W. Crous in 2014. Taxonomy Type genus: Pyricularia Sacc. 1880 Type species: Pyricularia grisea Sacc. 1880 The polyphyletic nature of Pyricularia has been resolved in 2014 leading to the definition of a new family, the Pyriculariaceae. Phylogenetic analysis showed that three clear clades could be distinguished. One clade corresponds to Magnaporthaceae (based on Nakataea), and two other clades were defined as new families: Pyriculariaceae (based on Pyricularia), and Ophioceraceae (based on Ophioceras). Description The Pyriculariaceae that reproduce sexually form perithecial fruiting bodies (ascomata), which are immersed, black and with long cylindrical necks covered in setae. Asci are subcylindrical, unitunicate, short-stipitate and with a large apical ring staining in Meltzer's iodine reagent. Ascospores are septate and fusiform. Asexual ...

Magnaporthe Grisea
''Magnaporthe grisea'', also known as rice blast fungus, rice rotten neck, rice seedling blight, blast of rice, oval leaf spot of graminea, pitting disease, ryegrass blast, Johnson spot, neck blast, wheat blast, and Imochi (Japanese:稲熱) is a plant-pathogenic fungus and model organism that causes a serious disease affecting rice. It is now known that ''M. grisea'' consists of a cryptic species complex containing at least two biological species that have clear genetic differences and do not interbreed. Complex members isolated from ''Digitaria'' have been more narrowly defined as ''M. grisea''. The remaining members of the complex isolated from rice and a variety of other hosts have been renamed ''Magnaporthe oryzae'', within the same ''M. grisea'' complex. Confusion on which of these two names to use for the rice blast pathogen remains, as both are now used by different authors. Members of the ''Magnaporthe grisea'' complex can also infect other agriculturally important cereal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

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] |
