摘要: 过氧化氢(Hydrogen peroxide, H2O2 ) 是植物细胞代谢过程中产生的一种活性氧, 被认为对细胞具有毒害作用。然而越来越多的研究证明, H2O2是植物细胞抵抗胁迫反应过程中的重要信号分子, 尤其H2O2在植物受到低温胁迫时所具有的信号调控功能越来越受到关注。作者综述了低温胁迫下的H2O2代谢情况, 并从H2O2与乙烯、水杨酸等信号分子的互作效应, 以及H2O2对抗冷基因、根系吸水性的调控来探讨其在抗冷信号转导过程中的功能及作用机制。

关键词: 过氧化氢, 低温胁迫, 信号转导, 抗冷

Abstract: Hydrogen peroxide (H2O2 ) is one reactive oxygen species in the metabolism of plant cell.Although it was considered to be harmful to plant cell, more and more evidences have proved that H2O2 is an important signal molecule in plant cell under stresses. This article discussed the H2O2 metabolism under low temperature stress, and listed the recent researches of H2O2 signal transduction, including interaction effect between H2O2 and other signal molecules, such as ethylene and salicylic acid, regulation of gene expression
and root water up take by H2O2.

Key words: hydrogen peroxide, low temperature stress, signal transduction, cold resistant
