Melatonin has attracted widespread attention after its discovery in higher plants. Tomato is a key model economic crop for studying fleshy fruits. Many studies have shown that melatonin plays important role in plant stress resistance, growth, and development. However, the research progress on the role of melatonin and related mechanisms in tomatoes have not been systematically summarized. This paper summarizes the detection methods and anabolism of melatonin in tomatoes, including (1) the role of melatonin in combating abiotic stresses, e.g., drought, heavy metals, pH, temperature, salt, salt and heat, cold and drought, peroxidation hydrogen and carbendazim, etc., (2) the role of melatonin in combating biotic stresses, such as tobacco mosaic virus and foodborne bacillus, and (3) the role of melatonin in tomato growth and development, such as fruit ripening, postharvest shelf life, leaf senescence and root development. In addition, the future research directions of melatonin in tomatoes are explored in combination with the role of melatonin in other plants. This review can provide a theoretical basis for enhancing the scientific understanding of the role of melatonin in tomatoes and the improved breeding of fruit crops.
褪黑素在高等植物中被发现后，引起了广泛关注。番茄是研究肉质果实的重要经济作物模式。许多研究表明，褪黑素在植物的抗逆性、生长和发育中发挥着重要作用。然而，关于褪黑素在番茄中的作用及相关机制的研究进展尚未得到系统总结。本文综述了番茄中褪黑素的检测方法和生物合成，包括（1）褪黑素在应对非生物胁迫中的作用，如干旱、重金属、pH 值、温度、盐、盐热、冷旱、过氧化物氢和多菌灵等，（2）褪黑素在应对生物胁迫中的作用，如烟草花叶病毒和食源性芽孢杆菌，以及（3）褪黑素在番茄生长发育中的作用，如果实成熟、采后货架期、叶片衰老和根系发育。此外，结合褪黑素在其他植物中的作用，探讨了番茄中褪黑素的未来研究方向。本综述可为增强对褪黑素在番茄中的作用以及提高果实作物的改良育种的科学认识提供理论基础。
