Jasmonic acid (JA) is an important part of plant growth regulator (PGR) family with their ubiquitous presence in higher plants with various roles in the physiology, growth and development of plants. Jasmonic acid is one of the chief composites to play a principle role in plant signaling during environmental stress, both biotic and abiotic. Jasmonates are very important bioactive molecule in the signal transduction mechanism during plant stress. Jasmonic acid pathway activation is initiated by the interaction of jasmonic acid and isoleucine (JA-Ile) coupled with CORONATINE insensitive (COI 1) receptors. This interaction further triggers proteolysis of jasmonate ZIM domain, a transcriptional repressor, triggering proteolysis. In this literature survey, we have emphasized on the important research findings on the role of jasmonic acid as chief regulator and modulator of plant growth and development during varied biotic and abiotic stress. The review discusses different plant systems Solanum lycopersicum, Arabidopsis thaliana, Malus baccata Borkh, Nicotianna attenuate, Brassica species in Brassica campestris, Brassica napus and Brassica juncea , used as models to study the role of jasmonic acid in various conditions like, regulating Mi 1.2, PR1 and PR6 genes expression, PIN mediated polar auxin transport, proline accumulation, jasmonic acid-absicisic acid interaction, oxidative damage by regulating the mechanism of AsA-GSH cycle under low root temperature, elicitor of (E)-α- bergamotene generation, CORONATINE INSENSITIVE 1 (irCOI1) regulation, xylogenesis in hypocotyls of seedlings subjected to jasmonic acid methyl-ester (JAMe) with and without 1 aminocyclopropane-1-carboxylic acid, indole-3-butyric acid and indole-3-acetic acid, PIN7 expression suppression by jasmonic acid.
