Tilletia Tritici
''Tilletia caries'' (synonymous with ''Tilletia tritici'') is a basidiomycete that causes common bunt of wheat. The common names of this disease are stinking bunt of wheat and stinking smut of wheat. This pathogen infects wheat, rye, and various other grasses. ''T. caries'' is economically and agriculturally important because it reduces both the wheat yield and grain quality. Life cycle Infection of the wheat occurs during germination of the plant seed and is favored by cool, wet conditions. Optimum conditions for spore germination are soil temperatures in the range of . Bunt fungi overwinter as dikaryotic teliospores typically on seed and occasionally in soil. The fungus infects the shoots of wheat seedlings before the plants emerge from the soil. After karyogamy, the teliospores germinate to form a basidium, on which 8–16 haploid basidiospores (primary sporidia) will develop. There are two mating types of basidiospores (+ and -) and they fuse to form H-shaped structures to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cephalosporium Gramineum
''Cephalosporium gramineum'' syn. ''Hymenula cerealis'' is a plant pathogen that causes cephalosporium stripe of wheat and other grasses. It was first reported in Japan in 1930. The disease can cause yield losses of up to 50% by causing death of tillers and reducing seed production and seed size. The disease causes broad yellow or brown stripes along the length of the leaf and discolouration of the leaf veins. The fungus spreads through the soil, and enters the plant through wounds in its roots. Early planting of winter wheat when the soil is warm gives a greater root system more subject to root breakage when the soil heaves affording more infection sites. Phosphate fertilizer and high moisture further exacerbate this condition. The symptoms are caused by the fungus invading the plants' vascular tissue. The fungus also produces a toxin which causes stunting of the plant and interferes with development. A glucopolysaccharide also appears to inhibit fluid movement in wheat.Pool, R ...

Cochliobolus Sativus
The fungus ''Cochliobolus sativus'' is the teleomorph (sexual stage) of ''Bipolaris sorokiniana'' (anamorph) which is the causal agent of a wide variety of cereal diseases. The Plant pathology, pathogen can infect and cause disease on roots (where it is known as Common root rot (wheat), common root rot), leaf and stem, and head tissue. ''C. sativus'' is extremely rare in nature and thus it is the Asexual reproduction, asexual or anamorphic stage which causes infections. The two most common diseases caused by ''B. sorokiniana'' are spot blotch and common root rot, mainly on wheat and barley crops. Identification The mycelium of ''B. sorokiniana'' is usually deep olive-brown. New cultures produce abundant simple conidiophores, which may be single or clustered and measure 6–10 x 110–220 μm with septations. Conidia develop laterally from pores beneath each conidiophore septum. Conidia are olive-brown and ovate to oblong, with rounded ends and a prominent basal scar. They measur ...

University Of Nebraska–Lincoln
The University of Nebraska–Lincoln (Nebraska, NU, or UNL) is a Public university, public Land-grant university, land-grant research university in Lincoln, Nebraska, United States. Chartered in 1869 by the Nebraska Legislature as part of the Morrill Land-Grant Acts, Morrill Act of 1862, the school was the University of Nebraska until 1968, when it absorbed the University of Nebraska Omaha, Municipal University of Omaha to form the University of Nebraska system. It is the state's oldest university and the flagship institution of the state-wide system. The university has been governed by the Board of Regents since 1871, whose members are elected by district to six-year terms. The university is organized into nine colleges: Agricultural Sciences and Natural Resources, Architecture, College of Arts and Sciences (University of Nebraska–Lincoln), Arts and Sciences, Business, College of Education and Human Sciences (University of Nebraska–Lincoln), Education and Human Sciences, Co ...

Black Point (disease)
Black point (blackpoint, kernel smudge or just smudge) is often considered a fungal disease that affects wheat, barley and rye. It is thought to be caused by various species of Alternaria, Fusarium, and Helminthosporium ''Helminthosporium'' is a genus of fungi belonging to the family Massarinaceae. The genus has a cosmopolitan distribution. Species The following species are recognised in the genus ''Helminthosporium'': *'' Helminthosporium abietis'' *'' H ..., and possibly other fungal genera. The fungus forms after the seeds have set but while they are still green and it is potentiated by high humidity. Infected areas are brown to black in color, and as the disease spreads the kernels may become shriveled. Occasionally the infected areas have a reddish tinge. Some authorities make a distinction between "black point" and "smudge". For them the disease is "black point" from initial infection until more than half of the kernel is infected, or when the disease has entered i ...

Sporobolomyces
''Sporobolomyces'' is a genus of fungi in the subdivision Pucciniomycotina. Species produce both yeast states and hyphal states. The latter form teliospores from which auricularioid (tubular and laterally septate) basidia emerge, bearing basidiospores. Yeast colonies are salmon-pink to red. ''Sporobolomyces'' species occur worldwide and have been isolated (as yeasts) from a wide variety of substrates. They produce ballistoconidia that are bilaterally symmetrical, they have Coenzyme Q10 or Coenzyme Q10(H2) as their major ubiquinone, they lack xylose in whole-cell hydrolysates, and they cannot ferment sugars. One species, '' Sporobolomyces salmonicolor'', is known to cause disease in humans. Species Molecular research, based on cladistic analysis of DNA sequences, has shown that ''Sporobolomyces'' sensu stricto is a monophyletic (natural) genus, but that many species previously placed in the genus belong elsewhere. The teleomorphic (hyphal) state was formerly referred to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
