摘　　要：植物体内合成的维生素C在植物抗氧化和自由基清除、光合作用和光保护、细胞生长和分裂以及一些重要次生代谢物和乙烯的合成等方面具有非常重要的生理功能。维生素C的生物合成途径及其代谢调控的基因工程研究最近取得了突破。It is becoming increasingly clear that vitamin C (L-ascorbic acid, AsA) is of crucialimportance in such processes as ROS detoxification, photosynthesis and photoprotection, cell divi-sion and growth. AsA is also a cofactor for some deoxygenase type enzymes involved in the synthe-sis of a number of other secondary metabolites and ethylene. A major breakthrough in plant AsAbiosynthesis and metabolic engineering has been made recently.
