Melatonin, a multifunctional molecule that is present in all living organisms studied, is synthesized in plant cells in several intercellular organelles including in the chloroplasts and in mitochondria. In plants, melatonin has a relevant role as a modulatory agent which improves their tolerance response to biotic and abiotic stress. The role of melatonin in stress conditions on the primary metabolism of plant carbohydrates is reviewed in the present work. Thus, the modulatory actions of melatonin on the various biosynthetic and degradation pathways involving simple carbohydrates (mono- and disaccharides), polymers (starch), and derivatives (polyalcohols) in plants are evaluated. The possible applications of the use of melatonin in crop improvement and postharvest products are examined.
褪黑素是一种存在于所有已研究的生物体内的多功能分子，它在植物细胞的几种细胞间细胞器中合成，包括叶绿体和线粒体。在植物中，褪黑素作为一种调节剂发挥着重要作用，可提高植物对生物和非生物胁迫的耐受性。本文综述了褪黑素在胁迫条件下对植物碳水化合物初级代谢的作用。因此，评估了褪黑素对植物中涉及单糖和二糖等简单碳水化合物、聚合物（淀粉）和衍生物（多元醇）的各种生物合成和降解途径的调节作用。研究了褪黑素在作物改良和采后产品中的可能应用。
