摘 要:

糖不仅作为淀粉合成的底物, 而且还具有信号转导的功能。近年的研究表明, 糖在植物生长发育、应激反应和产量形成等生命活动中作为渗透保护剂和(或)抗氧化剂起重要的防护作用。本文总结了植物中糖信号产生的途径、系统的组成、作用机制、对外界环境的响应以及其对逆境调控的最新研究进展, 并对未来的研究方向作出展望。

Abstract:

Sugar, as the substrate of starch synthesis, is also involved in signal transduction. In recent years, studies have shown that, as osmoprotectant and (or) antioxidant, sugar plays a protective role in plant life cycles, including its growth and development, stress response, yield formation and so on. This paper summarizes the lastest research concerning the pathway plant sugar signal is produced, systematic composition, mechanism, the response to external environment and its regulation to adversity, and overviews the direction of relative research in the future.

Key words: sugar; sugar signal; growth and development; stress tolerance response
