Jasmonates, Their Biosynthesis, Metabolism and Signalling Pathway in Plant Organisms

Jasmonates, derivatives of jasmonic acid, are lipid-derived oxylipins with cyclopentanone ring, produced as a result dioxygenation mediated by lipoxygenases. The biosynthesis acid is catalysed series different enzymes, starting from lipoxygenase, allene oxide synthase, cyclase and 12-oxophytodienoic reductase to the final three rounds β-oxidation. Consequently, few metabolites known jasmonates formed resulting acid. Some these active able work on jasmonate receptor thus start signalling pathway. Products gene expression this pathway have great significance in plant growth, development, reproduction, senescence also defence adaptation various adverse environmental conditions.
