Reactive oxygen species (ROS) play a critical role in plant development and stress responses, acting as key components in rapid signalling pathways. The 'ROS wave' triggers essential acclimation processes, ultimately ensuring plant survival under diverse challenges. This review explores recent advances in understanding the composition and functionality of the ROS wave within plant cells. During their initiation and propagation, ROS waves interact with other rapid signalling pathways, hormones and various molecular compounds. Recent research sheds light on the intriguing lack of a rigid hierarchy governing these interactions, highlighting a complex interplay between diverse signals. Notably, ROS waves culminate in systemic acclimation, a crucial outcome for enhanced stress tolerance. This review emphasizes the versatility of ROS, which act as flexible players within a network of short- and long-term factors contributing to plant stress resilience. Unveiling the intricacies of these interactions between ROS and various signalling molecules holds immense potential for developing strategies to augment plant stress tolerance, contributing to improved agricultural practices and overall ecosystem well-being.
活性氧（ROS）在植物发育和应激反应中起着关键作用，作为快速信号通路的关键组成部分。“ROS 波”触发了必要的适应过程，最终确保了植物在各种挑战下的生存。本综述探讨了近年来对植物细胞内 ROS 波的组成和功能的理解的进展。在其启动和传播过程中，ROS 波与其他快速信号通路、激素和各种分子化合物相互作用。最近的研究揭示了一个有趣的现象，即这些相互作用没有严格的等级制度，而是强调了不同信号之间的复杂相互作用。值得注意的是，ROS 波最终导致系统性适应，这是增强应激耐受性的关键结果。本综述强调了 ROS 的多功能性，ROS 作为参与植物应激弹性的短期和长期因素网络中的灵活参与者发挥作用。揭示 ROS 与各种信号分子之间的这些相互作用的复杂性，为开发增强植物应激耐受性的策略提供了巨大的潜力，有助于改进农业实践和整体生态系统福祉。
