摘　　要：对不同果实抗坏血酸(AsA,维生素C)积累特点、生物学功能和合成途径等进行了综述,分析了AsA受遗传与外在因素如光照、糖和激素等影响的共性问题,阐述转录因子、microRNA、DNA甲基化和翻译后修饰方式调控果实AsA合成与循环途径相关基因的模式,以期为后续果实AsA形成机制研究提供参考。The biological function,biosynthesis and accumulation characteristics of ascorbic acid(AsA or vitamin C)in fruit germplasm were summarized.It addresses such questions as the both genetic and environmental factors that affect its accumulation,such as sugars,hormones,light,and temperature.This study elaborates the regulatory mechanism of AsA biosynthesis and recycling by the transcription factors,microRNAs,DNA methylation and post-translational patterns.The goal is to provide a reference for the formation of fruit AsA in the future.
