Neocamarosporium Betae
''Neocamarosporium betae'' is a plant pathogen infecting ''Beta vulgaris'' (beet) and causes Phoma leaf spot. It was originally published and described in 1877 as ''Pleospora betae'' before being resolved as ''Neocamarosporium betae'' in 2015. It also causes leaf spot on Spinach plants. It contains the chemical substances betaenone A Betaenone A, like other betaenones ( B and C), is a secondary metabolite isolated from the fungus '' Pleospora betae'', a plant pathogen. Of the seven phytotoxins isolated in fungal leaf spots from sugar beet (''Beta vulgaris''), it showed 73% gro ..., B and C. ''Pleospora betae'' develops on dead beet residues and is a marsupial stage of the ''Phoma betae'' anamorph, parasitizing on beets and causing a number of harmful diseases.

Beta Vulgaris
''Beta vulgaris'' (beet) is a species of flowering plant in the subfamily Betoideae of the family Amaranthaceae. Economically, it is the most important crop of the large order Caryophyllales. It has several cultivar groups: the sugar beet, of greatest importance to produce table sugar; the root vegetable known as the beetroot or garden beet; the leaf vegetable known as chard or spinach beet or silverbeet; and mangelwurzel, which is a fodder crop. Three subspecies are typically recognised. All cultivars fall into the subspecies ''Beta vulgaris'' subsp. ''vulgaris''. The wild ancestor of the cultivated beets is the sea beet (''Beta vulgaris'' subsp. ''maritima''). Description ''Beta vulgaris'' is a herbaceous biennial or, rarely, perennial plant up to 120 cm (rarely 200 cm) height; cultivated forms are mostly biennial. The roots of cultivated forms are dark red, white, or yellow and moderately to strongly swollen and fleshy (subsp. ''vulgaris''); or brown, fibro ...

Betaenone A
Betaenone A, like other betaenones ( B and C), is a secondary metabolite isolated from the fungus '' Pleospora betae'', a plant pathogen. Of the seven phytotoxins isolated in fungal leaf spots from sugar beet (''Beta vulgaris''), it showed 73% growth inhibition ''Growth inhibition'' (GI) is a medical term pertaining to cancer therapy and the specific reduction in growth of tumors and oncogene cells by a chemical compound, mechanical therapy (e.g. electroporation), radiation, gene therapy, protein therapy, ....

Betaenone B
Betaenone B, like other betaenones ( A and C), is a secondary metabolite isolated from the fungus '' Pleospora betae'', a plant pathogen. Its phytotoxic properties have been shown to cause sugar beet leaf spots, which is characterized by black, pycnidia containing, concentric circles eventually leading to necrosis of the leaf tissue. Of the seven phytotoxins isolated in fungal leaf spots from sugar beet (''Beta vulgaris''), betaenone B showed the least amount of phytotoxicity showing only 8% inhibition of growth while betaenone A and C showed 73% and 89% growth inhibition, respectively. Betaenone B is therefore not considered toxic to the plant, but will produce leaf spots when present in high concentrations (0.33 μg/μL). While the mechanism of action of betaenone B has yet to be elucidated, betaenone C has been shown to inhibit RNA and protein synthesis. Most of the major work on betaenone B, including the initial structure elucidation of betaenone A, B and C as well as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betaenone C
Betaenone C, like other betaenones ( A and B), is a secondary metabolite isolated from the fungus '' Pleospora betae'', a plant pathogen. Of the seven phytotoxins isolated in fungal leaf spots from sugar beet (''Beta vulgaris''), it showed 89% growth inhibition. Betaenone C has been shown to act by inhibiting RNA and protein synthesis Protein biosynthesis (or protein synthesis) is a core biological process, occurring inside cells, balancing the loss of cellular proteins (via degradation or export) through the production of new proteins.

Fungal Plant Pathogens And Diseases
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'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Food Plant Pathogens And Diseases
Food is any substance consumed by an organism for nutritional support. Food is usually of plant, animal, or fungal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth. Different species of animals have different feeding behaviours that satisfy the needs of their unique metabolisms, often evolved to fill a specific ecological niche within specific geographical contexts. Omnivorous humans are highly adaptable and have adapted to obtain food in many different ecosystems. The majority of the food energy required is supplied by the industrial food industry, which produces food with intensive agriculture and distributes it through complex food processing and food distribution systems. This system of conventional agriculture relies heavily on fossil fuels, which means that the food and agricultur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
