Abiotic stresses are the primary sources of crop losses globally. The identification of key mechanisms deployed and established by plants in response to abiotic stresses is necessary for the maintenance of their growth and persistence. Recent discoveries have revealed that phytohormones or plant growth regulators (PGRs), mainly jasmonic acid (JA), have increased our knowledge of hormonal signaling of plants under stressful environments. Jasmonic acid is involved in various physiological and biochemical processes associated with plant growth and development as well as plant defense mechanism against wounding by pathogen and insect attacks. Recent findings suggest that JA can mediate the effect of abiotic stresses and help plants to acclimatize under unfavorable conditions. As a vital PGR, JA contributes in many signal transduction pathways, i.e., gene network, regulatory protein, signaling intermediates and enzymes, proteins, and other molecules that act to defend cells from the harmful effects of various environmental stresses. However, JA does not work as an independent regulator, but acts in a complex signaling pathway along other PGRs. Further, JA can protect and maintain the integrity of plant cells under several stresses by up-regulating the antioxidant defense. In this review, we have documented the biosynthesis and metabolism of JA and its protective role against different abiotic stresses. Further, JA-mediated antioxidant potential and its crosstalk with other PGRs have also been discussed.

非生物胁迫是全球作物损失的主要来源。确定植物响应非生物胁迫部署和建立的关键机制对于维持其生长和持久性是必要的。最近的发现表明，植物激素或植物生长调节剂 (PGR)，主要是茉莉酸 (JA)，增加了我们对压力环境下植物激素信号传导的了解。茉莉酸参与与植物生长发育相关的各种生理和生化过程，以及植物抵御病原体和昆虫攻击伤害的防御机制。最近的研究结果表明，JA 可以介导非生物胁迫的影响，帮助植物在不利条件下适应环境。作为一种重要的 PGR，JA 参与许多信号转导途径，即，基因网络、调节蛋白、信号中间体和酶、蛋白质和其他分子，它们可以保护细胞免受各种环境压力的有害影响。然而，JA 不作为独立的调节器工作，而是沿着其他 PGR 在复杂的信号通路中起作用。此外，JA 可以通过上调抗氧化防御来保护和维持植物细胞在多种胁迫下的完整性。在这篇综述中，我们记录了 JA 的生物合成和代谢及其对不同非生物胁迫的保护作用。此外，还讨论了 JA 介导的抗氧化潜力及其与其他 PGR 的串扰。JA 不作为独立的调节器工作，而是在沿着其他 PGR 的复杂信号通路中起作用。此外，JA 可以通过上调抗氧化防御来保护和维持植物细胞在多种胁迫下的完整性。在这篇综述中，我们记录了 JA 的生物合成和代谢及其对不同非生物胁迫的保护作用。此外，还讨论了 JA 介导的抗氧化潜力及其与其他 PGR 的串扰。JA 不作为独立的调节器工作，而是在沿着其他 PGR 的复杂信号通路中起作用。此外，JA 可以通过上调抗氧化防御来保护和维持植物细胞在多种胁迫下的完整性。在这篇综述中，我们记录了 JA 的生物合成和代谢及其对不同非生物胁迫的保护作用。此外，还讨论了 JA 介导的抗氧化潜力及其与其他 PGR 的串扰。
