Key message

Melatonin induces a delay in flowering stabilizing DELLA proteins and also promotes the transcription of FLC. In fruit set, melatonin is able to induce parthenocarpy. Melatonin promotes ripening and retards senescence of fruits.

Abstract

Melatonin is an animal hormone involved in many regulatory processes such as those related to sleep. Melatonin was discovered in plants in 1995 and is called phytomelatonin. Also in plants, a great variety of physiological processes have been described in which melatonin plays a role. In plants, melatonin is mainly involved in stress situations but also in germination, plant growth, rhizogenesis, senescence and as a protector agent improving important processes such as photosynthesis, CO₂ uptake, cell water economy and primary and secondary metabolism. Melatonin has been related to changes in the majority of plant hormones. Many revisions of stress situations have been published. However, melatonin and plant reproductive development have been poorly studied. The aim of this review is to provide an overview of works related to flowering, fruit set and development, including parthenocarpy and fruit ripening/senescence, and the role played by melatonin in the same.

褪黑素在开花，坐果和果实成熟中。

关键信息

褪黑素诱导开花稳定的DELLA蛋白延迟，并且还促进FLC的转录。在水果中，褪黑激素能够诱导单性结实。褪黑激素促进果实成熟并延缓其衰老。

抽象

褪黑激素是一种动物激素，参与许多调节过程，例如与睡眠有关的过程。褪黑素于1995年在植物中发现，被称为植物降钙素。同样在植物中，已经描述了褪黑激素起作用的多种生理过程。在植物中，褪黑素主要参与胁迫情况，但也参与发芽，植物生长，发根，衰老，并作为保护剂改善光合作用，CO ₂等重要过程摄取，细胞水分节约以及一次和二次代谢。褪黑激素与大多数植物激素的变化有关。压力状况的许多修订版本已经发布。但是，对褪黑激素和植物生殖发育的研究很少。这篇综述的目的是概述与开花，坐果和发育有关的工作，包括单性结实和果实成熟/衰老，以及褪黑激素在其中的作用。
