List Of Rice Varieties
This is a list of rice cultivars, also known as rice varieties. There are several species of grain called rice. Asian rice (''Oryza sativa)'' is most widely known and most widely grown, with two major subspecies (''indica'' and ''japonica'') and over 40,000 varieties. Also included in this list are varieties of African rice (''Oryza glaberrima'') and wild rice (genus ''Zizania''). Rice may vary in genetics, grain length, color, thickness, stickiness, aroma, growing method, and other characteristics, leading to many cultivars. For instance, over nine major rice cultivars exist to make sake alone. The two subspecies of Asian rice, indica and japonica, can generally be distinguished by length and stickiness. Indica rice is long-grained and unsticky, while japonica is short-grained and glutinous. Rice can also be divided based on processing type into the two broad categories of brown and white. Brown rice is whole grain, with only the inedible hull of the seed removed, while white r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Magnaporthe Poae
''Magnaporthe poae'' is an ascomycete fungus which causes the turfgrass disease commonly known as summer patch, or Poa patch. The disease occurs mostly on Kentucky bluegrass ''(Poa pratensis)'', Fescues ''(Festuca sp.),'' and on Annual bluegrass ''(Poa annua).'' Bentgrass (Agrostis sp.) may also become infected but shows very few symptoms and quickly recovers. Summer Patch will usually become noticeable between June and September, although small signs can appear at any time but are not noticeable because the turfgrass can recover quickly. Symptoms Symptoms of summer patch appear very similar to necrotic ring spot. This makes it very difficult to identify; if correct diagnosis is critical contact a local cooperative extension program or a qualified commercial lab. Although it is difficult to identify alone, if one takes into account grass species and cultural practices a trained eye can diagnose summer patch. Summer patch will appear as irregular patches, rings (less than 10&nbs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnaporthe Rhizophila
''Magnaporthe rhizophila'' is a fungus species in the family Magnaporthaceae. These dark mycelial fungi are common pathogens of cereal and grass roots. Rice blast is one disease known to be caused by M. rhizophila and presents with vascular discoloration in the host organism. The fungus lives best in drier humid conditions, explaining why it is most often found in the soils of Australia, South Africa, and the Southeastern United States. Development Similar to other ascomycota, the lifecycle of ''M. rhizophila'' is split into two parts: the sexual and asexual stages. The sexual lifestage is characterized by a globose (400-500 um wide) fruit-like body that contains the sexual spores, called a perithecia, which occurs in either singles or multiples. Perithecia are flask-like shaped and contain asci, which are septated, unitunicate stalks of 8 ascospores. The ascospores are biseriate, fusiform, and slightly curved or helical when naive. The perithecia is lined with cells calle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnaporthe Salvinii
''Magnaporthe salvinii'' is a fungus known to attack a variety of grass and rice species, including ''Oryza sativa'' (Asian rice) and ''Zizania aquatica'' (wild rice). Symptoms of fungal infection in plants include small, black, lesions on the leaves that develop into more widespread leaf rot, which then spreads to the stem and causes breakage. As part of its life cycle, the fungus produces sclerotia that persist in dead plant tissue and the soil. Management of the fungus may be effected by tilling the soil, reducing its nitrogen content, or by open field burning, all of which reduce the number of sclerotia, or by the application of a fungicide. Hosts and symptoms ''Magnaporthe salvinii'' (teleomorph)'','' also known as ''Sclerotium oryzae'' (anamorph) and ''Nakataea sigmoidae'' (anamorph)'','' is an ascomycete fungal pathogen that affects several rice and grass species, including: '' Echinochloa colona'', jungle rice ''Oryza sativa'', common rice ''Zizania aquatica'', annual ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Ascomycete
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) ascomycetes ...

Pathogen
In biology, a pathogen ( el, πάθος, "suffering", "passion" and , "producer of") in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ. The term ''pathogen'' came into use in the 1880s. Typically, the term ''pathogen'' is used to describe an ''infectious'' microorganism or agent, such as a virus, bacterium, protozoan, prion, viroid, or fungus. Small animals, such as helminths and insects, can also cause or transmit disease. However, these animals are usually referred to as parasites rather than pathogens. The scientific study of microscopic organisms, including microscopic pathogenic organisms, is called microbiology, while parasitology refers to the scientific study of parasites and the organisms that host them. There are several pathways through which pathogens can invade a host. The principal pathways have different episodic time frames, but soil has the longest ...

Sordariomycetes Genera
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 gr ...
