Salinity is a significant non-living environmental factor that negatively impacts plant growth and biomass. This chapter explores the multifaceted role of melatonin in enhancing salinity resilience through its regulatory effects on ionic homeostasis, redox networks, and stress-responsive pathways. By modulating ion transporters, enhancing antioxidant defenses, and regulating key genetic and molecular networks, melatonin alleviates ionic and oxidative stress in plants. Advances in omics technologies have provided deeper insights into melatonin’s influence on stress adaptation, while biotechnological applications such as priming, integration with biostimulants, and nanotechnology have demonstrated its potential in improving crop resilience. Future research directions emphasize bridging the gap between laboratory findings and field applications to harness melatonin’s potential for sustainable agriculture.

摘要

Salinity is a significant non-living environmental factor that negatively impacts plant growth and biomass. This chapter explores the multifaceted role of melatonin in enhancing salinity resilience through its regulatory effects on ionic homeostasis, redox networks, and stress-responsive pathways. By modulating ion transporters, enhancing antioxidant defenses, and regulating key genetic and molecular networks, melatonin alleviates ionic and oxidative stress in plants. Advances in omics technologies have provided deeper insights into melatonin’s influence on stress adaptation, while biotechnological applications such as priming, integration with biostimulants, and nanotechnology have demonstrated its potential in improving crop resilience. Future research directions emphasize bridging the gap between laboratory findings and field applications to harness melatonin’s potential for sustainable agriculture.
