摘要/Abstract

摘要： 根系是植物生长发育必不可缺的器官，不仅起到固定、支持植物的作用，还能从土壤中吸收植物生长发育必需的水分和无机盐。在植物根系生命活动中糖充当着营养成分和信号分子的双重作用，且与植物激素作用影响根系生长发育。近年来，国内外学者对糖调控植物根系生长发育做了大量研究，笔者综述了糖对根系生长发育的影响，介绍了糖信号转导及糖信号转导调控根系生长发育的机理，并从糖与植物激素的共同作用方面总结了糖调控根系生长发育机理的研究进展，以期为后续糖调控植物根系的相关研究提供参考。

Abstract: Root is an indispensable organ for plant growth and development, which could not only fix and support the plant body, but also absorb water and minerals from soil. In the life cycle of plant root, sugar plays dual roles as nutrients and signaling molecules, and combines with plant hormones to affect root growth and development. In recent years, the regulation mechanisms of sugar on the growth and development of plant roots had been reported. The author reviewed the influence of sugar on the root growth and development, and summarized sugar-regulated mechanisms from sugar signaling transduction and the interactions between sugar and plant hormones in plant root growth and development, proved some valuable information for the continuous research on sugar-regulated mechanisms in plant root.
