过氧化氢（H2O2）作为一种活性氧，在许多生物系统中广泛产生。它被认为是介导植物各种生理生化过程的重要信号分子。植物细胞的正常代谢会产生多种来源的 H2O2。此外，现在已经清楚一氧化氮 (NO) 和钙 (Ca2+) 在植物中起着信号分子的作用。 H2O2 和 NO 都参与植物发育和非生物反应。大量证据表明，NO 可以在与 H2O2 相似的应激条件下以相似的动力学生成。 H2O2 和 NO 之间的相互作用对于调节植物转导过程具有重要的功能意义。此外，H2O2 和 Ca2+ 之间也存在密切的相互作用，以响应植物的发育和非生物胁迫。细胞对 H2O2 和 Ca2+ 信号系统的反应很复杂。 H2O2 和 Ca2+ 信号传导之间存在大量相互作用，以响应多种刺激。本综述旨在介绍这些证据，帮助我们理解 H2O2、NO 和 Ca2+ 信号之间的串扰，这些信号调节植物生长和发育以及对非生物胁迫的其他细胞和生理反应。
Hydrogen peroxide (H2O2), as a reactive oxygen species, is widely generated in many biological systems. It has been considered as an important signaling molecule that mediates various physiological and biochemical processes in plants. Normal metabolism in plant cells results in H2O2 generation, from a variety of sources. Also, it is now clear that nitric oxide (NO) and calcium (Ca2+) function as signaling molecules in plants. Both H2O2 and NO are involved in plant development and abiotic responses. A wide range of evidences suggest that NO could be generated under similar stress conditions and with similar kinetics as H2O2. The interplay between H2O2 and NO has important functional implications to modulate transduction processes in plants. Moreover, close interaction also exists between H2O2 and Ca2+ in response to development and abiotic stresses in plants. Cellular responses to H2O2 and Ca2+ signaling systems are complex. There is quite a bit of interaction between H2O2 and Ca2+ signaling in responses to several stimuli. This review aims to introduce these evidences in our understanding of the crosstalk among H2O2, NO, and Ca2+ signaling which regulates plant growth and development, and other cellular and physiological responses to abiotic stresses.
