Abstract Melatonin is a kind of multifunctional hormone, analogous to indoleacetic acid in structure. To uncover the relationship between exogenous melatonin and the phenylalanine pathway, the liquid chromatography mass spectrometry (LC MS) was performed to quantify endogenous melatonin and individual anthocyanin content. RT-qPCR was used to explore the expression of primary genes involved in anthocyanin biosynthesis. In the present study, we found that the morphology and endogenous melatonin content of strawberries showed a significant improvement and increase in the M50 compared with the other groups. Additionally, anthocyanin accumulation and genes up-regulation, in both the M50 and the M100, all revealed higher levels than that of the control. In conclusion, this work revealed the positive relationship between exogenous melatonin and the phenylalanine metabolism of strawberries.

对采后草莓苯丙氨酸代谢相关的外源性褪黑激素的洞察

摘要 褪黑激素是一种多功能激素，在结构上类似于吲哚乙酸。为了揭示外源性褪黑激素与苯丙氨酸途径之间的关系，进行了液相色谱质谱 (LC MS) 以量化内源性褪黑激素和单个花青素含量。RT-qPCR 用于探索参与花青素生物合成的主要基因的表达。在本研究中，我们发现草莓的形态和内源性褪黑激素含量与其他组相比，M50 有显着改善和增加。此外，在 M50 和 M100 中，花青素积累和基因上调都显示出高于对照的水平。综上所述，
