Curvularia Kusanoi
''Curvularia'' is a genus of hyphomycete (mold) fungi which can be pathogens but also act as beneficial partners of many plant species. They are common in soil. Most ''Curvularia'' species are found in tropical regions, though a few are found in temperate zones. ''Curvularia'' is defined by the type species ''C. lunata'' (Wakker) Boedijn. ''Curvularia lunata'' appears as shiny velvety-black, fluffy growth (on the fungus colony surface). These fluffy 'hairs', which really are branching, fine filamentous structures called hyphae, are divided inside by cell walls named septae (-> the hyphae are 'septate'). The walls of these hyphae contain dark pigments, which makes for their black appearance and which is called 'dematiaceous'. The hyphae produce brown spore bearing organs, 'conidiophores', which are distinguished by their 'geniculate'shape, meaning they have bends of abrupt kneelike angles. The immobile, asexual fungal spores born on those conidiophores, the conidia, proconid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curvularia Geniculata
''Curvularia geniculata'' is a fast-growing anamorphic fungus in the division Ascomycota, most commonly found in soil, especially in areas of warmer climates. The fungus is a pathogen, mainly causing plant and animal infections, and rarely causing human infections. ''C. geniculata'' is characterized by its curved conidia, which has a dark brown centre and pale tapered tips, and produces anti-fungal compounds called Curvularides A-E. History and taxonomy The fungus was discovered by American botanist Samuel Mills Tracy and mycologist Franklin Sumner Earle in Starkville, Mississippi 1894 on Love grass (''Eragrostis rachitricha'') grown from imported seeds. They classified the fungus as ''Helminthosporium geniculatum''; however, the ''Heliminthosporium'' species later got segregated into four different genera, one being the genus ''Curvularia''. In 1923, Karel Bernard Boedijn, a Dutch botanist and mycologist, reclassified the fungus as ''Curvularia geniculata'' which is the asex ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Fungorum
''Index Fungorum'' is an international project to index all formal names (Binomial nomenclature, scientific names) in the fungus Kingdom (biology), kingdom. As of 2015, the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research New Zealand Limited, Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate Correct name (botany), correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page, a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of Synonym (taxonomy), synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized b ...

Necrotic Ring Spot
Necrosis () is a form of cell injury which results in the premature death of cells in living tissue by autolysis. The term "necrosis" came about in the mid-19th century and is commonly attributed to German pathologist Rudolf Virchow, who is often regarded as one of the founders of modern pathology. Necrosis is caused by factors external to the cell or tissue, such as infection, or trauma which result in the unregulated digestion of cell components. In contrast, ''apoptosis'' is a naturally occurring programmed and targeted cause of cellular death. While apoptosis often provides beneficial effects to the organism, necrosis is almost always detrimental and can be fatal. Cellular death due to necrosis does not follow the apoptotic signal transduction pathway, but rather various receptors are activated and result in the loss of cell membrane integrity and an uncontrolled release of products of cell death into the extracellular space. This initiates an inflammatory response in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Spring
A hot spring, hydrothermal spring, or geothermal spring is a Spring (hydrology), spring produced by the emergence of Geothermal activity, geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through fault (geology), faults to hot rock deep in the Earth's crust. Hot spring water often contains large amounts of dissolved minerals. The chemistry of hot springs ranges from acid sulfate springs with a pH as low as 0.8, to alkaline chloride springs saturated with silica, to bicarbonate springs saturated with carbon dioxide and carbonate minerals. Some springs also contain abundant dissolved iron. The minerals brought to the surface in hot springs often feed communities of extremophiles, microorganisms adapted to extreme conditions, and it is possible that life on Earth had its origin in hot springs. Humans have made use of hot springs for bathing, relaxation, or medical therapy for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dichanthelium Lanuginosum
''Dichanthelium lanuginosum'' is a species of rosette grass native to North America. It is most common in the central and eastern United States. It is found in a variety of habitats, mostly in open, dry areas. A variety, ''D. lanuginosum'' var. ''thermale'', grows in geothermal areas of Yellowstone National Park, United States. It is able to withstand high temperatures and high acidity in its rhizosphere. In 2007 it was found that the heat tolerance is conferred to the grass by a symbiosis between a fungus and a virus A virus is a submicroscopic infectious agent that replicates only inside the living Cell (biology), cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses are .... When it is colonised by the fungus '' Curvularia protuberata'' and the fungus is in turn colonised by a particular virus, the grass is able to tolerate soil temperatures of up to 65 °C that would otherwise be ...
