Melatonin and serotonin are indoleamines first identified as neurotransmitters in vertebrates; they have now been found to be ubiquitously present across all forms of life. Both melatonin and serotonin were discovered in plants several years after their discovery in mammals, but their presence has now been confirmed in almost all plant families. The mechanisms of action of melatonin and serotonin are still poorly defined. Melatonin and serotonin possess important roles in plant growth and development, including functions in chronoregulation and modulation of reproductive development, control of root and shoot organogenesis, maintenance of plant tissues, delay of senescence, and responses to biotic and abiotic stresses. This review focuses on the roles of melatonin and serotonin as a novel class of plant growth regulators. Their roles in reproductive and vegetative plant growth will be examined including an overview of current hypotheses and knowledge regarding their mechanisms of action in specific responses.
褪黑素和血清素是最早在脊椎动物中被鉴定为神经递质的吲哚胺；现在人们发现它们普遍存在于所有生命形式中。褪黑素和血清素在哺乳动物中被发现几年后，在植物中也被发现，但现在几乎在所有植物科中都已证实它们的存在。褪黑素和血清素的作用机制仍不清楚。褪黑素和血清素在植物生长发育中具有重要作用，包括在生物钟调节和生殖发育调控、根和茎器官发生的控制、植物组织的维持、衰老延迟以及对生物和非生物胁迫的反应等方面的功能。本综述重点关注褪黑素和血清素作为一类新型植物生长调节剂的作用。将研究它们在植物生殖和营养生长中的作用，包括对当前关于它们在特定反应中作用机制的假说和知识的概述。
