Helotiales
Helotiales is an order of the class Leotiomycetes within the division Ascomycota. The taxonomy within Helotiales has been debated. It has expanded significantly as genomic techniques for taxonomical identification have become more commonly used. , the order is estimated to contain 30 accepted families, 519 genera, and 6266 species. Helotiales is the largest order of non-stromatic discomycetes that usually, but not always, have brightly coloured apothecia. Many members of the family have obviously cup-shaped ascomata with little or no stipes. They are usually found fruiting on coarse or large wood debris as well as on other organic matter. Part of these discomycetes are limited to a specific host range, this goes as far as to not just being limited to one particular plant, additionally some species need a particular part of that plant. Description *Helotiales is distinguished by its disc or cup-shaped apothecia. *Its asci are only slightly thickened in contrast to other Leot ...

Ericoid Mycorrhiza
The ericoid mycorrhiza is a mutualistic relationship formed between members of the plant family Ericaceae and several lineages of mycorrhizal fungi. This symbiosis represents an important adaptation to acidic and nutrient poor soils that species in the Ericaceae typically inhabit, including boreal forests, bogs, and heathlands. Molecular clock estimates suggest that the symbiosis originated approximately 140 million years ago. Structure and function Ericoid mycorrhizas are characterized by fungal coils that form in the epidermal cells of the fine hair roots of ericaceous species.Smith, S. E. and D. J. Read. 2008. Mycorrhizal Symbiosis, Third Edition. Academic Press. Ericoid mycorrhizal fungi establish loose hyphal networks around the outside of hair roots, from which they penetrate the walls of cortical cells to form intercellular coils that can densely pack individual plant cells. However, the fungi do not penetrate plasma membranes of plant cells. Evidence suggests that coils ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monilinia Fructicola
''Monilinia fructicola'' is a species of fungus in the order Helotiales. A plant pathogen, it is the causal agent of brown rot of stone fruits. Stone fruit (summer fruit) Stone fruits such as apricot and peaches originated in China and spread through old trade routes 3–4000 years ago. Nectarines are more recent (at least 2000 years). Cherries and European plums originated in Europe, although the Japanese plum originated in China.Whiting. J. R. (n.d.). Science behind your garden. Retrieved October 27, 2007, from http://www.gardenscience.co.nz Trees exposed to cold in autumn and early spring can develop cankers under the bark of the trunk or branches. Cankers are usually associated with the production of amber-coloured gum that contains bacteria and oozes on to the outer bark. Unfortunately, there are few control methods for fungal spores apart from copper sprays. Symptoms Brown rot causes blossom blight, twig blight; twig canker and fruit rot.Ministry of Agriculture.

Leotiomycetes
The Leotiomycetes are a class of ascomycete fungi. Many of them cause serious plant diseases. Systematics The class Leotiomycetes contains numerous species with an anamorph placed within the ''fungi imperfecti'' (deuteromycota), that have only recently found their place in the phylogenetic system. The older classifications placed Leotiomycetes into the Discomycetes clade ( inoperculate Discomycetes). Molecular studies have recently shed some new light to the still obscure systematics. Most scholars consider Leotiomycetes a sister taxon to Sordariomycetes in the phylogenetic tree of Pezizomycotina. Its division into subclasses have received strong support by the molecular data, but the overall monophyly of Leotiomycetes is dubious. The order Lichinodiales and family Lichinodiaceae, newly circumscribed in 2019 to contain the genus cyanolichen genus '' Lichinodium'', is the first known group of lichen-forming fungi in the Leotiomycetes.

Sclerotium Cepivorum
''Stromatinia cepivora'' is a fungus in the division Ascomycota. It is the teleomorph of ''Sclerotium cepivorum'', the cause of white rot in onions, garlic, and leeks. The infective sclerotia remain viable in the soil for many years and are stimulated to germinate by the presence of a susceptible crop. Pathogenesis ''Sclerotium cepivorum'' is the asexual reproductive form of ''Stromatinia cepivora'' and is a plant pathogen, causing white rot in ''Allium'' species, particularly onions, leeks, and garlic. On a worldwide basis, white rot is probably the most serious threat to ''Allium'' crop production of any disease. This is a soil borne fungus and affects susceptible crops planted in infected soil containing sclerotia. The sclerotia that are developed in the life cycle can be spread to other fields by unsuccessful sanitation practices.The sclerotia can remain viable in the soil for years and germinate with a susceptible host to cause disease; therefore it is important to pract ...

Stone Fruit
In botany, a drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pit'', ''stone'', or ''pyrena'') of hardened endocarp with a seed (''kernel'') inside. These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries (polypyrenous drupes are exceptions). The definitive characteristic of a drupe is that the hard, lignified stone is derived from the ovary wall of the flower. In an aggregate fruit, which is composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet, and may together form an aggregate fruit. Such fruits are often termed ''berries'', although botanists use a different definition of ''berry''. Other fleshy fruits may have a stony enclosure that comes from the seed coat surrounding the seed, but such fruits are not drupes. Flowering plants that produce drupes include coffee, jujube, mango, olive, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
