摘要: 酸性转化酶是蔗糖代谢的关键酶,在植物体中具有重要的生理作用。近十几年来,许多植物酸性转化酶基因已经克隆,其基因表达调控的研究也取得了很大的进展。本文综述了植物酸性转化酶﹑ 基因及其蛋白结构、基因表达的器官和发育特异性以及糖、受伤、病原胁迫和激素对基因表达的调节和蛋白抑制因子对酶活性的影响,并讨论了当前在该研究领域存在的问题。

Abstract: Plant acid invertase is one of critical enzymes in sucrose metabolism and plays an important role during plant growth and development. In the last decade, acid invertase genes have been cloned from many plant species, and great progress has been made in studies of the regulation of expression of these genes. This paper summarizes the research in elucidating the structure of acid invertase genes and proteins, regulation of gene expression by organ and developmental specificity, sugar, wounding, pathogen infection, stress and hormones, and regulation of enzyme activity by proteinous inhibitors. Problems in this field are also discussed.
