This study aimed to identify the regulatory mechanisms of white, blue, red lights on carotenoid and tocochromanol biosynthesis in mung bean sprouts. Results showed that three lights stimulated the increase of the predominated lutein (3.2-8.1 folds) and violaxanthin (2.1-6.1 folds) in sprouts as compared with dark control, as well as β-carotene (20-36 folds), with the best yield observed under white light. Light signals also promoted α- and γ-tocopherol accumulation (up to 1.8 folds) as compared with dark control. The , and (1.24-6.34 folds) exhibited high expression levels under light quality conditions, resulting in an overaccumulation of carotenoids. The , and were decisive genes in tocochromanol biosynthesis, and were expressed up to 4.19 folds as compared with control. Overall, the results could provide novel insights into light-mediated regulation and fortification of carotenoids and tocopherols, as well as guide future agricultural cultivation of mung bean sprouts.
本研究旨在确定白色、蓝色、红色光对绿豆芽中类胡萝卜素和生育三烯酚生物合成的调控机制。结果表明，与黑暗对照相比，三种光均刺激了豆芽中主要叶黄素（3.2 - 8.1倍）和紫黄质（2.1 - 6.1倍）以及β-胡萝卜素（20 - 36倍）的增加，在白光下产量最高。与黑暗对照相比，光信号还促进了α-和γ-生育酚的积累（高达1.8倍）。 、 和 （1.24 - 6.34倍）在光质条件下表现出高表达水平，导致类胡萝卜素过度积累。 、 和 是生育三烯酚生物合成中的决定性基因，与对照相比表达量高达4.19倍。总体而言，这些结果可为光介导的类胡萝卜素和生育酚调控及强化提供新见解，并指导未来绿豆芽的农业种植。
