Glomeraceae
The ''Glomeraceae'' are a family of arbuscular mycorrhizal (AM) fungi that form symbiotic relationships (mycorrhizas) with plant roots. The family was circumscribed In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius. Not every polyg ... in 1989. References Fungus families Glomerales {{Glomeromycota-stub ...

Funneliformis
''Funneliformis'' is a genus of fungi in the family Glomeraceae. All species are arbuscular mycorrhizal (AM) fungi that form symbiotic relationships (mycorrhizaa) with plant roots. The genus was circumscribed in 2010 by Arthur Schüßler and Christopher Walker, with ''Funneliformis mosseae'' (named after the biologist Barbara Mosse and originally described in 1968 as a species of ''Endogone'') as the type species. The generic name refers to the funnel-shaped spore base present in several species.

Glomus (fungus)
''Glomus'' is a genus of arbuscular mycorrhizal (AM) fungi, and all species form symbiotic relationships (mycorrhizae) with plant roots. ''Glomus'' is the largest genus of AM fungi, with ''ca.'' 85 species described, but is currently defined as non-monophyletic. Classification ''Glomus'' is one of the genera in the family Glomeraceae, in the division Glomeromycota. Some members of the genus were originally described as ''Sclerocystis'' species, but this genus has been entirely transferred to ''Glomus''. However, further taxonomic changes are likely as the phylogeny of AM fungi becomes better understood. ''Glomus'' is likely related to the fossil fungus '' Glomites'', discovered in the Rhynie chert deposits from the Early Devonian (400 million years ago). Ecology As with other AM fungi, all ''Glomus'' species are thought to be obligate symbionts, dependent on their mycorrhizal association with plant roots to complete their life cycle. They cannot be cultured in the laboratory i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizophagus Irregularis
''Rhizophagus irregularis'' (previously known as ''Glomus intraradices'') is an arbuscular mycorrhizal fungus used as a soil inoculant in agriculture and horticulture. ''Rhizophagus irregularis'' is also commonly used in scientific studies of the effects of arbuscular mycorrhizal fungi on plant and soil improvement. Until 2001, the species was known and widely marketed as ''Glomus intraradices'', but molecular analysis of ribosomal DNA led to the reclassification of all arbuscular fungi from Zygomycota phylum to the Glomeromycota phylum.

Mycelia
Mycelium (plural mycelia) is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. Fungal colonies composed of mycelium are found in and on soil and many other substrates. A typical single spore germinates into a monokaryotic mycelium, which cannot reproduce sexually; when two compatible monokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form fruiting bodies such as mushrooms. A mycelium may be minute, forming a colony that is too small to see, or may grow to span thousands of acres as in ''Armillaria''. Through the mycelium, a fungus absorbs nutrients from its environment. It does this in a two-stage process. First, the hyphae secrete enzymes onto or into the food source, which break down biological polymers into smaller units such as monomers. These monomers are then absorbed into the mycelium by facilitated diffusion and active transport. Mycelia are vital in terrestrial and aquatic ecosystems for their role in t ...

Vicia Faba
''Vicia faba'', commonly known as the broad bean, fava bean, or faba bean, is a species of vetch, a flowering plant in the pea and bean family Fabaceae. It is widely cultivated as a crop for human consumption, and also as a cover crop. Varieties with smaller, harder seeds that are fed to horses or other animals are called field bean, tic bean or tick bean. Horse bean, ''Vicia faba'' var. ''equina'' Pers., is a variety recognized as an accepted name. This legume is very common in Southern European, Northern European, East Asian, Latin American and North African cuisines. Some people suffer from favism, a hemolytic response to the consumption of broad beans, a condition linked to a metabolism disorder known as G6PDD. Otherwise the beans, with the outer seed coat removed, can be eaten raw or cooked. In young plants, the outer seed coat can be eaten, and in very young plants, the seed pod can be eaten.

Yolande Dalpé
Yolande Dalpé is a former Research Scientist with Agriculture and Agri-Food Canada. She became the first mycologist in Ottawa to study the taxonomy of mycorrhizal fungi. Her research focuses on developing new information on taxonomy, phylogeny, distribution and biology of fungi, including systematic research related to biosecurity/alien invasive species as well as species involved in the development of bioproducts. She was awarded the Lawson Medal by the Canadian Botanical Association for her "cumulative, lifetime contributions to Canadian botany, for the research she has performed in mycology, and has been recognized nationally and internationally."

Rhizophagus (fungus)
''Rhizophagus'' is a genus of arbuscular mycorrhizal (AM) fungi that form symbiotic relationships (mycorrhizas) with plant roots. The genome of ''Rhizophagus irregularis'' (formerly ''Glomus intraradices'') was recently sequenced In genetics and biochemistry, sequencing means to determine the primary structure (sometimes incorrectly called the primary sequence) of an unbranched biopolymer. Sequencing results in a symbolic linear depiction known as a sequence which suc .... References Glomerales Fungus genera Taxa described in 1896 {{glomeromycota-stub ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Arbuscular Mycorrhiza
An arbuscular mycorrhiza (AM) (plural ''mycorrhizae'', a.k.a. ''endomycorrhiza'') is a type of mycorrhiza in which the symbiont fungus (''AM fungi'', or AMF) penetrates the cortical cells of the roots of a vascular plant forming arbuscules. (Not to be confused with ectomycorrhiza or ericoid mycorrhiza.) Arbuscular mycorrhizae are characterized by the formation of unique structures, arbuscules and vesicles, by Glomeromycota and Mucoromycota, sister clades of the more well-known and diverse dikaryan fungi (all three are together called "symbiomycota"). AM fungi help plants to capture nutrients such as phosphorus, sulfur, nitrogen and micronutrients from the soil. It is believed that the development of the arbuscular mycorrhizal symbiosis played a crucial role in the initial colonisation of land by plants and in the evolution of the vascular plants. It has been said that it is quicker to list the plants that do not form endomycorrhizae than those that do. This symbiosis is a ...

Fungi
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'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
