Fusarium Larvarum
''Fusarium'' is a large genus of filamentous fungi, part of a group often referred to as hyphomycetes, widely distributed in soil and associated with plants. Most species are harmless saprobes, and are relatively abundant members of the soil microbial community. Some species produce mycotoxins in cereal crops that can affect human and animal health if they enter the food chain. The main toxins produced by these ''Fusarium'' species are fumonisins and trichothecenes. Despite most species apparently being harmless (some existing on the skin as commensal members of the skin flora), some ''Fusarium'' species and subspecific groups are among the most important fungal pathogens of plants and animals. The name of ''Fusarium'' comes from Latin ''fusus'', meaning a spindle. Taxonomy The taxonomy of the genus is complex. A number of different schemes have been used, and up to 1,000 species have been identified at times, with approaches varying between wide and narrow concepts ...

Johann Heinrich Friedrich Link
Johann Heinrich Friedrich Link (2 February 1767 – 1 January 1851) was a German naturalist and botanist. Biography Link was born at Hildesheim as a son of the minister August Heinrich Link (1738–1783), who taught him love of nature through collection of 'natural objects'. He studied medicine and natural sciences at the Hannoverschen Landesuniversität of Göttingen, and graduated as MD in 1789, promoting on his thesis ''"Flora der Felsgesteine rund um Göttingen"'' (Flora of the rocky beds around Göttingen). One of his teachers was the famous natural scientist Johann Friedrich Blumenbach (1752–1840). He became a private tutor (''Privatdozent'') in Göttingen. In 1792 he became the first professor of the new department of chemistry, zoology and botany at the University of Rostock. During his stay at Rostock, he became an early follower of the antiphlogistic theory of Lavoisier, teaching about the existence of oxygen instead of phlogiston. He was also a proponent of the ...

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 ...

Fusarium Culmorum
''Fusarium culmorum'' is a fungal plant pathogen and the causal agent of seedling blight, foot rot, ear blight, stalk rot, common root rot and other diseases of cereals, grasses, and a wide variety of monocots and dicots. In coastal dunegrass (''Leymus mollis''), ''F. culmorum'' is a nonpathogenic symbiont conferring both salt and drought tolerance to the plant. Identification Colonies grow rapidly on potato dextrose agar. The aerial mycelium is whitish to yellow, tan or pale orange, but becomes brown to dark brown to red-brown with age. Under alternating conditions of light and temperature, rings of spore masses may be formed by some isolates. Macroconidia Microconidia are absent, but macroconidia are usually abundant. The sporodochia are orange to brown color and relatively common. The macroconidia are thick and bluntly pointed at their apex, and conspicuously wider above the center of the spore. The dorsal side is somewhat curved, but the ventral side is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusarium Crookwellense
''Fusarium crookwellense'' (syn. ''Fusarium cerealis'') is a species of fungus in the family Nectriaceae. It is known as a plant pathogen that infects agricultural crops. The fungus was first described in 1982 after it was found infecting potatoes in Australia.Sugiura, Y., et al. (1993)''Fusarium poae'' and ''Fusarium crookwellense'', fungi responsible for the natural occurrence of nivalenol in Hokkaido.''Applied and Environmental Microbiology'' 59(10) 3334-8. It causes plant diseases such as corn ear rot and wheat head blight. It has also been found on hops causing a necrotic blight on the cones. Like other species in genus ''Fusarium'', this fungus produces mycotoxins. It is a source of nivalenol, 4-acetylnivalenol, and zearalenone Zearalenone (ZEN), also known as RAL and F-2 mycotoxin, is a potent estrogenic metabolite produced by some ''Fusarium'' and ''Gibberella'' species. Specifically, the ''Gibberella zeae ,'' the fungal species where zearalenone was initially detected, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusarium Circinatum
''Fusarium circinatum'' is a fungal plant pathogen that causes the serious disease pitch canker on pine trees and Douglas firs (''Pseudotsuga menziesii''). The most common hosts of the pathogen include slash pine ('' Pinus elliottii''), loblolly pine (''Pinus taeda''), Monterey pine (''Pinus radiata''), Mexican weeping pine (''Pinus patula''), and Douglas fir. Like other ''Fusarium'' species in the phylum Ascomycota, it is the asexual reproductive state of the fungus and has a teleomorph, ''Gibberella circinata''. Distribution This fungus is believed to have originated in Mexico. It spread to the eastern United States in 1946 and by 1986 had reached the western United States. It was first recorded in Japan in the 1980s, in South Africa in 1990, in Chile and Spain in the mid 1990s and in Italy in 2007. Host species In California this canker has been recorded on nine different species of pine (''Pinus'') and on Douglas fir (''Pseudotsuga menziesii''). In Europe and Asia it has bee ...
