Abstract: Gardenia leaves were used as materials to study the effect of melatonin on flavonoid content and related gene expression in Gardenia leaves under dark conditions by transcriptome sequencing and liquid chromatography. The melatonin not only delayed the senescence of Gardenia, but also delayed the yellowing of leaves by reducing the accumulation of flavonoids through inhibiting the expression of related genes such as flavonoids biosynthetic pathways. Our experiment provided practical guidance for retarding the yellowing of Gardenia leaves under dark stress, and the reference to the use of melatonin to control and delay the yellowing of leaves.

Key words: Gardenia, dark stress, melatonin, flavonoids, transcriptome, HPLC
