jasmonate(s): a group of cyclopentanone derivatives, originate biosynthetically from linolenic acid via and inducible octadecanoid pathway
consisting of at least seven enzymatic steps; the end product is (+)-7-iso-jasmonic acid, a physiologically active substance that is rapidly converted to its stereoisomer, stable (–)-jasmonic acid chem phys
jasmonic acid: it is distributed throughout higher plants, synthesized from linolenic acid via the octaadecanoic pathway; an important role seems
to be its operation as a “master switch,” responsible for the activation of signal transduction pathways in response to predation and pathogen attack; proteins encoded by jasmonate-induced genes
include enzymes of alkaloid and phytoalexin synthesis, storage proteins, cell wall constituents, and stress protectants; the wound-induced formation of proteinase inhibitors is an example, in which jasmonic acid
combines with abscisic acid and ethylene to protect the plant from predation chem phys
