Recent Progress on Melatonin-Induced Salinity Tolerance in Plants: An Overview

In this context, it is necessary to select and develop salt-tolerant genotypes that can grow in salty soils have high yields, formulate strategies which may enhance the plant survival under salinity stress. Melatonin (N-acetyl-5-methoxytryptamine) an important biological hormone provides resistance abiotic stress conditions be secreted by plants. concentration plants varies depending on genotype, temperature growth period. Increase melatonin associated with increased SNAT HIOMAT/ASMT enzyme activity. It plays role gibberellic acid abscisic biosynthesis during germination development. Exogenous application of significantly alleviates chlorophyll degradation stomatal closure caused salt stress, improves photosynthesis enhances plants' tolerance. Besides reduces harmful effects regulating physiology, improving morphology, activities antioxidant enzymes. The present review discusses recent studies effect physiology against impacts development been given according findings various researches. also highlights mechanim/s melatonin-induced tolerance
