摘要: 种子休眠与萌发是截然不同而又紧密联系的两个生理过程, 也是植物生命周期中的关键阶段, 对自然状态下的植物物种繁殖与地理分布以及农业生产均具有重要意义, 且两个过程受不同内源激素和环境信号之间的精确互作调控。大量研究表明, 蛋白质磷酸化修饰作为一种重要的翻译后修饰方式, 参与调控种子休眠与萌发以及植物逆境胁迫响应等过程并发挥重要作用。该文简要介绍了蛋白质磷酸化、去磷酸化修饰过程及其功能, 系统总结了蛋白质磷酸化修饰在种子休眠与萌发过程中的调控作用, 并展望了未来的研究方向。

Abstract: Seed dormancy and germination are two distinct but closely related physiological processes, which are also key stages during plant life-cycle and have great significance to agricultural production, plant species reproduction, and geographical distribution. These processes are precisely regulated by interactions between different endogenous phytohormones and environmental signals. A large number of studies have shown that protein phosphorylation, plays an important role in regulating seed dormancy and germination, as well as plant response to stresses. This review paper briefly introduces the procedures and functions of protein phosphorylation and dephosphorylation modification, and summarizes the regulatory roles of protein phosphorylation modification in seed dormancy and germination. Finally, some future research directions are prospected.
