摘要:

干旱、盐害以及极端温度等非生物胁迫是影响植物生长发育的重要因子。植物在遭受胁迫时,活性氧的快速积累导致胞内氧化还原稳态被打破,进一步诱导产生次级氧化胁迫损伤。除了初级非生物胁迫胁迫信号外,植物细胞也需要产生一系列的次级氧化胁迫信号。氧化还原信号的感知与传递在植物氧化胁迫应答过程中发挥重要的作用,其生物化学基础是功能蛋白质发生的氧化还原翻译后修饰,分别又由多种具有氧化还原活性的小分子介导。本文综述了近年来植物氧化还原信号的研究进展,展望了未来的研究方向,以期为研究植物氧化胁迫应答及氧化还原信号转导提供参考。

Abstract:

Abiotic stress such as drought, salt, and extreme temperature are important factors affecting plant growth and development. The rapid accumulation of reactive oxygen species can lead to the disruption of intracellular redox homeostasis, further inducing secondary oxidative stress damage, when plants are subjected to stress. In addition to primary stress signals, plant cells also need secondary oxidative stress signals to respond abiotic stress. The perception and transmission of redox signals play an important role in plant oxidative stress response, which relies on reversible oxidative post-translational modifications of proteins mediated by a variety of small molecules with redox activity. This article reviews the research progress in plant redox signals, and discusses the future direction in this field, aiming to provide reference for further research on plant oxidative stress response and redox signal transduction.

Key words: oxidative stress, reactive oxygen species, redox signaling, post-translational modification
