Our results provide insights into polyphenol biosynthesis in sprouts and microgreens. These changes were likely due to the changes in the expression of the photoreceptor genes CRY-D, PHOT2, PHYE and light response genes ( PIF3 and HY5). Moreover, MYB111, MYB3, MYB4, MYB1 and MYC2 were critical regulators of polyphenol biosynthesis in mung bean sprouts. Pearson correlation analysis showed that PAL, F3H, F3’H and F3′5’H expression correlated highly with rutin, whereas ANS expression paralleled anthocyanin biosynthesis. Most genes involved in polyphenol biosynthesis were activated under different light quality conditions, resulting in an overaccumulation of phenylpropanoids. Interestingly, ferulic acid and vitexin responded selectively to blue light and red light, severally. Experimental results showed that three light qualities significantly enhanced the contents of caffeic acid, rutin, vitexin, genistin and delphinidin 3-glucoside. This study investigated the effects of light qualities on the kinetic changes and metabolic regulation mechanism of light signal-mediating polyphenols in three mung bean sprout cultivars. Mung bean ( Vigna radiata) sprouts are a popular sprouting vegetable all over the world and are an excellent source of polyphenols with high antioxidant activity. Light quality acts as a signal molecule, strongly enhancing polyphenol biosynthesis in sprouts. We investigated the mechanism of the effect of different light qualities on the synthesis and regulation of mung bean sprouts.
