Salinity stress poses a significant challenge to crop productivity worldwide. Developing effective strategies to enhance salinity tolerance in plants is crucial for sustainable agriculture. Jasmonic acid (JA), a key plant hormone, has emerged as a promising tool for mitigating the adverse effects of salinity stress. Jasmonic acid seed priming, a novel approach, involves pre-soaking seeds in a JA solution to induce physiological and molecular changes that enhance germination, seedling growth, and stress tolerance. This article provides an overview of the effects of JA seed priming on plants under salinity stress. Jasmonic acid seed priming promotes osmotic stress tolerance by enhancing the accumulation of Osmo protectants and activating antioxidant defense systems. It modulates hormonal signalling pathways, promoting the breakdown of dormancy and stimulating germination. Additionally, JA seed priming induces gene expression changes, leading to the upregulation of stress-responsive genes and the activation of metabolic pathways involved in nutrient mobilization. Overall, JA seed priming represents a promising and sustainable approach for alleviating salinity stress in plants. Understanding the molecular and physiological mechanisms underlying the effects of JA seed priming will facilitate its practical implementation for crop improvement programs aimed at enhancing salinity tolerance and ensuring food security in saline environments.
