title: [Jasmonic acid and its participation in defence reactions of plant organism].
abstract: The main stages and inductors of biosynthesis of jasmonic acid and its derivatives, peculiarities of their content depending on the type of tissue, organ, plant age, mechanical irritation, injury and the impact of pathogens are considered. Data about use of mutant and transgenic plants with disturbed biosynthesis and perception of jasmonic acid for research ofjasmonate value in the induction of defense reactions are presented. Enzymes that are involved in the biosynthesis of jasmonic acid, synergistic (with abscisic acid, ethylene) and antagonistic (with salicylic acid) action of jasmonic acid with other phytohormones are described. There are data on the induction of jasmonic acid defense reactions in plants by the activation of genes encoding the synthesis ofthionins, extensins, phytoalexins and phenolic compounds. It is stressed that the ways of signal transmission for defense reactions induction are largely unknown and require further study.
