抗坏血酸（MA）含量以及L - 半乳糖 - 1 - 磷酸磷酸酶（GPPase）和L - 半乳糖 - 1,4 - 内酯脱氢酶（GalLDH）的mRNA水平在强光下升高，在黑暗中降低。此外，GPPase和GalLDH的启动子区域包含光响应顺式作用元件。这些结果表明，在水稻中，抗坏血酸的合成受光调控。
The ascorbic acid (MA) content and the mRNA levels of L-galactose-I-phosphate phosphatase (GPPase), and L-galactono-1.4-lactone dehydrogenase (GalLDH) increased by intense light, and decreased in the dark. Moreover, the promoter regions of GPPase and GalLDH contained light responsible cis-elements. These results suggest that in rice. AsA synthesis is regulated by light.
