摘　　要：抗坏血酸是一类水溶性小分子化合物,不仅可以清除植物体内因生物和非生物胁迫产生的活性氧,提高植物抵抗逆境的能力,还可以延缓衰老,调节植物生长。本文对植物抗坏血酸的生理功能、生物合成途径以及相关关键基因、影响抗坏血酸合成的外在因素和内部因子进行简要阐述,并对植物抗坏血酸未来研究方向进行了展望。Ascorbic acid is a kind of water-soluble small-molecule compound,which can not only remove reactive oxygen species produced by biological and abiotic stress in plants,but improve the ability of plants to resist stress.It can also delay aging and regulate plant growth.In this paper,physiological functions and biosynthesis pathway of ascorbic acid in plants,its related key genes,as well as external and internal factors affecting ascorbic acid synthesis are briefly reviewed.Future research directions of plant ascorbic acid are prospected.
