doi:10.13560/j.cnki.biotech.bull.1985.2020-1027

摘要/Abstract

摘要：

植物光合作用的产物主要以蔗糖的形式在植物体内进行从源到库的运输。蔗糖转运蛋白是此过程的重要参与者,其表达和调控与植物中光合作用产物的分配紧密关联,从而调控着植物的生长发育、结果结实、抗逆抗病等性状。蔗糖转运蛋白的表达受到植物发育时期、外界环境条件及激素的影响。蔗糖转运蛋白的调控机制有转录因子的调节、基因内部序列调控、蛋白质的磷酸化、蛋白之间的相互作用及质子转运体的活性调节等。综述了国内外对蔗糖转运蛋白表达与活性的调控因素及机制等最新的研究内容,以期为从多角度上探索植物蔗糖转运蛋白的功能和调控机制提供相关研究信息和思路。

Abstract:

The products of plant photosynthesis mainly transport from source to sink in the form of sucrose in plants. The sucrose transporters play key role in this process,their expressions and regulations are closely related to the distribution of photosynthetic products in plants,thus they consequently regulate plant growth and development process,production and resistance to stress and disease. The expressions of sucrose transporters are affected by plant developmental period,environmental conditions and plant hormones. The regulation mechanisms of sucrose transporters include the regulation of transcription factors,the internal sequence regulating of genes,the phosphorylation of proteins,the interaction between proteins,and the activity regulating of proton transporters. This paper reviews the latest results on the factors regulating the expressions and activities of sucrose transporters as well as the mechanisms,aiming to provide relevant research information and ideas in exploring the functions and regulating mechanisms of plant sucrose transporters from multi-angle.

Key words: sucrose transporter, expression, regulation
