过氧化氢（H2O2）是高等植物在环境适应过程中发生的各种生理过程的重要信号分子。本文讨论了在各种生物和非生物胁迫下 H2O2 在信号转导和基因调控中的作用。基于使用公共和我们自己的转录组数据的比较分析，我们认为 H2O2 是一种独立的介质，可以响应任何植物胁迫，并且在对胁迫因素组合的协同响应中发挥作用。在这里，我们提出 H2O2 作为一种信号分子，能够触发一组保守基因的基因激活，这些基因形成包含数十个转录因子的通用转录子网络。
Hydrogen peroxide (H2O2) is an important signaling molecule for various physiological processes that take place in higher plants during environmental adaptation. This article addresses the role of H2O2 in signal transduction and gene regulation in the context of a variety of biotic and abiotic stresses. Based on a comparative analysis using public and our own transcriptome data, we consider H2O2 as an independent mediator that acts in response to any of the plant stresses and also as having a role in the synergetic response to combinations of stress factors. Here, we propose H2O2 as a signal molecule that is able to trigger gene activation of a conserved set of genes that make a universal transcriptional subnetwork comprising tens of transcription factors.
