Beet
The beetroot is the taproot portion of a beet plant, usually known in North America as beets while the vegetable is referred to as beetroot in British English, and also known as the table beet, garden beet, red beet, dinner beet or golden beet. It is one of several cultivated varieties of ''Beta vulgaris'' grown for their edible taproots and leaves (called beet greens); they have been classified as ''B. vulgaris'' subsp. ''vulgaris'' Conditiva Group. Other cultivars of the same species include the sugar beet, the leaf vegetable known as chard or spinach beet, and mangelwurzel, which is a fodder crop. Three subspecies are typically recognized. Etymology ''Beta'' is the ancient Latin name for beetroot,Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 70 possibly of Celtic origin, becoming ''bete'' in Old English. ''Root'' derives from the late Old English ''rōt'', itself from Old Norse ''rót''. History The domestic ...

Rhizoctonia Solani
''Rhizoctonia solani'' is a species of fungus in the order Cantharellales. Basidiocarps (fruit bodies) are thin, effused, and web-like, but the fungus is more typically encountered in its anamorphic state, as hyphae and sclerotia. The name ''Rhizoctonia solani'' is currently applied to a complex of related species that await further research. In its wide sense, ''Rhizoctonia solani'' is a facultative plant pathogen with a wide host range and worldwide distribution. It causes various plant diseases such as root rot, damping off, and wire stem. It can also form mycorrhizal associations with orchids. Taxonomy In 1858, the German plant pathologist Julius Kühn observed and described a fungus on diseased potato tubers and named it ''Rhizoctonia solani'', the species epithet referring to ''Solanum tuberosum'' (potato). The disease caused was well known before the discovery and description of the fungus. In 1956, Dutch mycologist M.A. Donk published the new name ''Thanatephorus cucumer ...

Erysiphe Betae
''Erysiphe betae'' is a Plant Pathology, plant pathogen. It is a form of powdery mildew that can affect crops of sugar beet, when it can cause up to a 30% yield loss.Heffer, V., M. L. Powelson, K. B. Johnson, and N. Shishkoff. "Identification of Powdery Mildew Fungi anno 2006." Identification of Powdery Mildew Fungi. APS, 2006. Web. 14 Nov. 2016. The fungus occurs worldwide in all regions where sugar beet is grown and it also infects other edible crops, e.g. beetroot. Identification This pathogen is a strict obligated parasite, and therefore can only be identified when ''in planta''. Often to properly identify this pathogen, some form of microscopic analysis is needed when it is only found on one type of plant. This can be done through isolation and observation of cleistothecia, which are the product of sexual reproduction. Disease symptoms * Symptoms appear as dirty white, circular, floury patches on either sides of the leaves. * Under favourable environmental conditions, entire ...

Phymatotrichum Omnivorum
Texas root rot (also known as Phymatotrichopsis root rot, Phymatotrichum root rot, cotton root rot, or, in the older literature, Ozonium root rot) is a disease that is fairly common in Mexico and the southwestern United States resulting in sudden wilt and death of affected plants, usually during the warmer months. It is caused by a soil-borne fungus named ''Phymatotrichopsis omnivora'' that attacks the roots of susceptible plants. It was first discovered in 1888 by Pammel and later named by Duggar in 1916. A monograph of this disease, which includes a historical review, was written by R.B. Streets and H.E. Bloss in 1973. Host and symptoms ''Phymatotrichopsis omnivora'' is a necrotic fungal pathogen that has a very broad host range, attacking almost 2000 dicotyledonous species. It inhabits alkaline, calcareous soils in southwestern United States. It particularly targets dicots as most monocots are immune. Economically important plant hosts affected by the pathogen include: p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fusarium Oxysporum 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 specia ...

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 ...
