Fusarium Subglutinans
''Fusarium subglutinans'' is a fungal plant pathogen. Taxonomy ''Fusarium subglutinans'' is the anamorph of ''Gibberella fujikuroi''. Fusarium strains in the ''Gibberella fujikuroi'' species complex cause diseases in a number of economically important plants. DNA sequencing data reveals the presence of two major groups representing cryptic species in ''F. subglutinans''. These were further divided into groups that appeared to be reproductively isolated in the environment which suggests that they are undergoing separation into distinct taxa. One such divergent group is ''Fusarium subglutinans f. sp. pini'' which causes pitch canker of pine trees. It is a synonym of ''Fusarium circinatum''. Other members of the complex and their host plants are: *''Fusarium moniliforme'' - Maize *''Fusarium oxysporum'' - Pine *''Fusarium proliferatum ''Fusarium proliferatum'' is a fungal A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes ...

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 ...

Teleomorph, Anamorph And Holomorph
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 ...

Gibberella Fujikuroi
''Gibberella fujikuroi'' is a fungal plant pathogen. It causes ''bakanae'' disease in rice seedlings. Another name is foolish seedling disease. It gets that name because the seeds can be infected, leading to disparate outcomes for the plant. There are not many diseases that initiate similar symptoms as bakanae. Hosts and symptoms ''Gibberella fujikuroi'' is most widely known for its disease producing capabilities in rice, but barley, millet, sugarcane and maize are also susceptible. In all infected plants, similar symptoms have been found, though rice has been most predominantly studied. The most telltale symptom of Bakanae is the tall, spindly look of the plant. This is a result of the gibberellins, or growth hormones, the fungus secretes. Infected plants are easy to pick out, then, as they often rise above the rest of the healthy plants with regularly secreted growth hormones. However, it is also possible that stunting may occur, along with Chlorosis of the leaves of the pl ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Crypsis
In ecology, crypsis is the ability of an animal or a plant to avoid observation or detection by other animals. It may be a predation strategy or an antipredator adaptation. Methods include camouflage, nocturnality, subterranean lifestyle and mimicry. Crypsis can involve visual, olfactory (with pheromones) or auditory concealment. When it is visual, the term cryptic coloration, effectively a synonym for animal camouflage, is sometimes used, but many different methods of camouflage are employed by animals or plants. Overview There is a strong evolutionary pressure for animals to blend into their environment or conceal their shape, for prey animals to avoid predators and for predators to be able to avoid detection by prey. Exceptions include large herbivores without natural enemies, brilliantly colored birds that rely on flight to escape predators, and venomous or otherwise powerfully armed animals with warning coloration. Cryptic animals include the tawny frogmouth (feather pat ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pine Pitch Canker
''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 ...

Pinus
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...

Fusarium Moniliforme
''Fusarium verticillioides'' is the most commonly reported fungal species infecting maize (''Zea mays''). ''Fusarium verticillioides'' is the accepted name of the species, which was also known as ''Fusarium moniliforme''. The species has also been described as mating population A of the ''Fusarium fujikuroi'' species complex (formally known as ''Gibberella fujikuroi'' species complex). ''F. verticllioides'' produces the mutagenic chemical compound fusarin C. ''F. verticillioides'' produces a group of disease-causing mycotoxins—fumonisins—on infected kernels. Control The growth of all strains of ''F. verticillioides'' is significantly inhibited by an iodine-containing fungistatic Fungistatics are anti-fungal agents that inhibit the growth of fungus (without killing the fungus). The term ''fungistatic'' may be used as both a noun and an adjective. Fungistatics have applications in agriculture, the food industry, the paint ind ...

Fusarium Oxysporum
''Fusarium oxysporum'' (Schlecht as emended by Snyder and Hansen), an ascomycete fungus, comprises all the species, varieties and forms recognized by Wollenweber and Reinking within an infrageneric grouping called section Elegans. It is part of the family Nectriaceae. Although their predominant role in native soils may be as harmless or even beneficial plant endophytes or soil saprophytes, many strains within the ''F. oxysporum'' complex are soil borne pathogens of plants, especially in agricultural settings. Taxonomy While the species, as defined by Snyder and Hansen, has been widely accepted for more than 50 years, more recent work indicates this taxon is actually a genetically heterogeneous polytypic morphospecies, whose strains represent some of the most abundant and widespread microbes of the global soil microflora. Genome The ' family of transposable elements was first discovered by Daboussi ''et al.'', 1992 in several ''formae speciales'' and Davière ''et al.'', 2001 ...

Fusarium Subglutinans F
''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 of ...
