摘　要：

抗坏血酸是水溶性抗氧化有机小分子, 在植物中广泛存在, 并可作为某些氧化还原酶的辅酶。本文主要综述了抗坏血酸在植物中的合成、转运和所参与的多种生理作用, 如细胞周期调控、成花诱导、光合结构保护、碳代谢和胁迫响应等, 并对今后植物中抗坏血酸的相关研究提出展望。

Abstract:

Ascorbic acid (AsA) is a widespread potent water-soluble antioxidant in plants, and acts as co-factor of some reductase. This review focused on the biosynthesis, transportation and plant physiological functions of ascorbic acid in plants, such as cell cycle regulation, floral induction, photo-protection, carbon metabolism and stress response et al., and provided prospect for future research.

Key words: ascorbic acid; physiological function; cell cycle; floral induction; photosynthesis
