Trichoderma Sordidum
''Trichoderma'' is a genus of fungi in the family Hypocreaceae that is present in all soils, where they are the most prevalent culturable fungi. Many species in this genus can be characterized as opportunistic avirulent plant symbionts. This refers to the ability of several ''Trichoderma ''species to form mutualistic endophytic relationships with several plant species. The genomes of several ''Trichoderma'' species'' ''have been sequenced and are publicly available from the JGI. Taxonomy The genus was described by Christiaan Hendrik Persoon in 1794, but the taxonomy has remained difficult to resolve. For a long time, it was considered to consist of only one species, ''Trichoderma viride'', named for producing green mold. Subdivision In 1991, Bissett divided the genus into five sections, partly based on the aggregate species described by Rifai: *''Pachybasium'' (20 species) *''Longibrachiatum'' (10 species) *''Trichoderma'' *''Saturnisporum'' (2 species) *''Hypocreanum'' ...

Christian Hendrik Persoon
Christiaan Hendrik Persoon (1 February 1761 – 16 November 1836) was a German mycologist who made additions to Linnaeus' mushroom taxonomy. Early life Persoon was born in South Africa at the Cape of Good Hope, the third child of an immigrant Pomeranian father and Dutch mother. His mother died soon after he was born; at the age of thirteen his father (who died a year later) sent him to Europe for his education. Education Initially studying theology at Halle, at age 22 (in 1784) Persoon switched to medicine at Leiden and Göttingen. He received a doctorate from the "Kaiserlich-Leopoldinisch-Carolinische Deutsche Akademie der Naturforscher" in 1799. Later years He moved to Paris in 1802, where he spent the rest of his life, renting an upper floor of a house in a poor part of town. He was apparently unemployed, unmarried, poverty-stricken and a recluse, although he corresponded with botanists throughout Europe. Because of his financial difficulties, Persoon agreed to do ...

Clades
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms t ...

Conidia
A conidium ( ; ), sometimes termed an asexual chlamydospore or chlamydoconidium (), is an asexual, non-motile spore of a fungus. The word ''conidium'' comes from the Ancient Greek word for dust, ('). They are also called mitospores due to the way they are generated through the cellular process of mitosis. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal. Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive between species and, before the development of molecular techniques at the end of the 20th century, was widely used for identification of (''e.g.'' ''Metarhizium'') species. The terms microconidia and macroconidia are sometimes used. Conidiogenesis There are two main types of conidium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichoderma Longibrachiatum
''Trichoderma longibrachiatum'' is a fungus in the genus ''Trichoderma''. In addition to being a distinct species, ''T. longibrachiatum'' also typifies one of several clades within ''Trichoderma'' which comprises 21 different species. ''Trichoderma longibrachiatum'' is a soil fungus which is found all over the world but mainly in warmer climates. Many species from this clade have been adopted in various industries because of their ability to secrete large amounts of protein and metabolites. Taxonomy and nomenclature ''Trichoderma'' is a diverse genus with other 135 species in Europe alone. This species was first characterized by Mien Rifai in 1969. It is an exclusively anamorphic species complex allied with the sexual species, ''Hypocrea schweinitzii''. Evolutionarily ''T. longibrachiatum'' is the youngest clade of ''Trichoderma''. Growth and morphology ''Trichoderma longibrachiatum'' is a fast-growing fungus. It typically produces off-white colonies that change to greyish gre ...

Gliocladium
''Gliocladium''Corda (1840) ''Icon. fung. (Prague)'' 4: 30. is an asexual fungal genus in the Hypocreaceae. Certain other species including ''Gliocladium virens'' were recently transferred to the genus ''Trichoderma'' and ''G. roseum'' became '' Clonostachys rosea f. rosea'' in the Bionectriaceae. ''Gliocladium'' is a mitosporic, filamentous fungus. Species of ''Gliocladium'' rarely produce a sexual state. Most pathogenic, disease-causing fungi in humans are mitosporic like ''Gliocladium''. ''Gliocladium'' is filamentous; it grows tubular, elongated, and thread-like. It can be considered a contaminant. Species ''Species fungorum'' currently (July 2018) lists the remaining species (+ ''G. zaleskii''): * '' Gliocladium africanum'' Eichelb. (1906) * '' Gliocladium album'' (Preuss) Petch (1939) * '' Gliocladium ammoniphilum'' Pidopl. & Bilaĭ (1950) * '' Gliocladium atrum'' J.C. Gilman & E.V.

Phialide
The phialide ( ; el, phialis, diminutive of phiale, a broad, flat vessel) is a flask-shaped projection from the vesicle (dilated part of the top of conidiophore) of certain fungi. It projects from the mycelium without increasing in length unless a subsequent increase in the formation of conidia occurs. It is the end cell of a phialosphore.

Anamorphs
In mycology, the terms teleomorph, anamorph, and holomorph apply to portions of the life cycles of fungi in the phyla Ascomycota and Basidiomycota: *Teleomorph: the sexual reproductive stage (morph), typically a fruiting body. *Anamorph: an asexual reproductive stage (morph), often mold-like. When a single fungus produces multiple morphologically distinct anamorphs, these are called synanamorphs. *Holomorph: the whole fungus, including anamorphs and teleomorph. Dual naming of fungi Fungi are classified primarily based on the structures associated with sexual reproduction, which tend to be evolutionarily conserved. However, many fungi reproduce only asexually, and cannot easily be classified based on sexual characteristics; some produce both asexual and sexual states. These problematic species are often members of the Ascomycota, but a few of them belong to the Basidiomycota. Even among fungi that reproduce both sexually and asexually, often only one method of reproduction can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
