褪黑激素（N-acetyl-5-methoxytryptamine，简称MT）是动物体内广泛存在的一种激素，在植物的各个方面都得到了越来越多的研究。本文综述了褪黑激素在植物对盐、干旱、低温、高温、氧化等非生物胁迫和病原菌感染等生物胁迫的调控作用。我们强调了内源性褪黑激素水平在应激条件下的变化，以及外源性褪黑激素应用对广泛代谢组、转录组和蛋白质组的重编程。此外，褪黑激素介导的胁迫信号和潜在的机制在植物中进行了广泛的讨论。因此，对褪黑激素介导的植物逆境信号转导机制的研究还有待进一步深入。
As a widely known hormone in animals, melatonin (N-acetyl-5-methoxytryptamine) has been more and more popular research topic in various aspects of plants. To summarize the these recent advances, this review focuses on the regulatory effects of melatonin in plant response to multiple abiotic stresses including salt, drought, cold, heat and oxidative stresses and biotic stress such as pathogen infection. We highlight the changes of endogenous melatonin levels under stress conditions, and the extensive metabolome, transcriptome, and proteome reprogramming by exogenous melatonin application. Moreover, melatonin-mediated stress signaling and underlying mechanism in plants are extensively discussed. Much more is needed to further study in detail the mechanisms of melatonin-mediated stress signaling in plants.
