Recent trends in jasmonate signaling pathway

Abstract

Jasmonates (JA) are a new class of plant hormones that has recently been worked out regulating the interweaving plant responses against invading microbes, herbivores, mechanical damage, and other environmental stresses. Their interactions are extensive working at the forefront of root or shoot tissues through volatile regulators, or they are regulated interdependently through the cross talk of other established growth regulators. Jasmonates, the product of octadecanoid pathway, have recently emerged as a versatile regulator of plant physiological and defense responses after salicylates. Most of the components of their signaling pathway have been identified through mutant studies. A progress towards the interaction of JA with other phytohormones is underway. Present review sheds the light on the recent progress made in identification and working mechanism of jasmonate receptor complex, its downstream signaling pathway, and the molecular interaction of its components with the signaling pathways of some other plant hormones.
