JASMONOMICS: Jasmonic Acid Dynamics in Regulating Plant Stress Responses and Developmental Homeostasis: Biosynthesis, Signaling, and Antioxidant Mechanisms & Crosstalk with Phytohormones
Abstract
“Jasmonomics” refers to the comprehensive study of jasmonic acid (JA) dynamics, highlighting its role in plant stress responses, growth regulation, and developmental processes. Abiotic stresses, including extreme temperatures, salinity, drought, and heavy metal toxicity, provide substantial challenges to global agricultural productivity, leading to major losses in crop yields. JA, a lipid-derived phytohormone, is essential in these stress responses. Produced via the octadecanoid pathway, with 12-oxo-phytodienoic acid (12-OPDA) as a crucial step, jasmonic acid (JA) regulates multiple stress-adaptive pathways, including the initiation of antioxidant defence systems. JA also promotes the formation of secondary metabolites, such as flavonoids and alkaloids, which aid in stress resilience and cellular detoxification. The interaction with other phytohormones, including abscisic acid, ethylene, and salicylic acid, enhances stress responses by synchronising transcriptional and post-transcriptional regulatory networks. The interplay of JA, JAZ repressors, and MYC transcription factors is essential for regulating gene expression and optimising resource distribution between growth and defence under stress circumstances. Future study seeks to elucidate jasmonic acid transport routes, its function in signal perception, and its synergistic or antagonistic interactions with other hormonal pathways. Progress in JA-mediated metabolic engineering presents promising approaches for improving crop resilience by focussing on stress response pathways. This study underscores the diverse function of JA in alleviating abiotic stress and accentuates its potential as a natural regulator to enhance plant development and defence, so supporting sustainable agricultural operations amid shifting climatic conditions.
