Fusicoccin Biosynthesis Pathway
Fusicoccins are organic compounds produced by a fungus. It has detrimental effect on plants and causes their death. Fusicoccins are diterpenoid glycosides produced by the fungus ''Fusicoccum amygdali'', which is a parasite of mainly almond and peach trees. It stimulates a quick acidification of the plant cell wall; this causes the stomata to irreversibly open, which brings about the death of the plant. Fusicoccins contains three fused carbon rings and another ring which contains an oxygen atom and five carbons. Fusicoccin was and is extensively used in research regarding the plant hormone auxin and its mechanisms. Biosynthesis Fusicoccin is a member of a diterpenoid class which shares a 5-8-5 ring structure and is called fusicoccane. In fungi, fusicoccin is biosynthesized via ''Phomopsis amygdali'' fusicoccadiene synthase (PaFS) from universal C5 isoprene units dimethylallyl diphosphate (DMAPP) and isopentenyl diphosphate (IPP). PaFS has two domains, a C-terminal prenyltransfera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organic Compound
In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living t ...
