褪黑激素（N-乙酰基-5-甲氧基色胺）是一种普遍存在的分子，在不同的生物体中具有多效性作用。它在人类、动物和植物中发挥着许多重要的功能；这些范围从调节动物的昼夜节律到控制植物的衰老。在这篇综述中，我们总结了有关不同植物物种中褪黑激素存在的现有信息，并强调了其生物合成和作用机制。我们还收集了有关褪黑素应用对具有重要商业价值的作物的影响的现有信息，以改善其生长和发育。此外，我们还发现了褪黑激素在植物中可能发挥作用的许多新方面，例如，其在改善水果和蔬菜的储存寿命和质量方面的功能，在嫁接过程中维管束重新连接中的作用，以及通过改变根结构从根部吸收养分的作用。另一个潜在的重要方面是通过传统和现代育种方法相结合生产富含褪黑素的粮食作物（谷物、水果和蔬菜），以增强植物对生物和非生物胁迫的抵抗力，从而提高作物产量和产品的营养保健价值，从而解决粮食安全问题。
Melatonin (N-acetyl-5-methoxytryptamine) is a ubiquitous molecule with pleiotropic actions in different organisms. It performs many important functions in human, animals, and plants; these range from regulating circadian rhythms in animals to controlling senescence in plants. In this review, we summarize the available information regarding the presence of melatonin in different plant species, along with highlighting its biosynthesis and mechanisms of action. We also collected the available information on the effects of melatonin application on commercially important crops to improve their growth and development. Additionally, we have identified many new aspects where melatonin may have possible roles in plants, for example, its function in improving the storage life and quality of fruits and vegetables, its role in vascular reconnection during the grafting process and nutrient uptake from roots by modifying root architecture. Another potentially important aspect is the production of melatonin-rich food crops (cereals, fruits, and vegetables) through combination of conventional and modern breeding approaches, to increase plant resistance against biotic and abiotic stress, leading to improved crop yields, and the nutraceutical value of produce to solve food security issues.
