Melatonin, also known as N-acetyl-5-methoxytryptamine, is a biological indolamine with important plant biology consequences. Its synthesis happens naturally in plants, which contributes to its potential use in promoting sustainable agriculture. Melatonin, which acts as a modulator as well as a bio-stimulator and plant growth regulator, has a wide range of beneficial effects for plants. One of its important functions is to increase a plant's resistance to biotic and abiotic stressors. Drought, waterlogging, severe temperatures, salt, and alkalinity are examples of stressors. This article emphasizes the significance of melatonin-synthesizing microorganisms and dives into the role of exogenous melatonin in giving abiotic stress tolerance. It also investigates melatonin's reactivity to microorganisms and its role in phytoremediation processes.
