Drought stress is a pivotal environmental factor impacting rice production and presents a significant challenge to sustainable agriculture worldwide. This review synthesizes the latest research advancements in the regulatory mechanisms and signaling pathways that rice employs in response to drought stress. It elaborates on the adaptive changes and molecular regulatory mechanisms that occur in rice under drought conditions. The review highlights the perception and initial transmission of drought signals, key downstream signaling networks such as the MAPK and Ca pathways, and their roles in modulating drought responses. Furthermore, the discussion extends to hormonal signaling, especially the crucial role of abscisic acid (ABA) in drought responses, alongside the identification of drought-resistant genes and the application of gene-editing technologies in enhancing rice drought resilience. Through an in-depth analysis of these drought stress regulatory signaling pathways, this review aims to offer valuable insights and guidance for future rice drought resistance breeding and agricultural production initiatives.
干旱胁迫是影响水稻生产的关键环境因素，对全球可持续农业构成重大挑战。本综述综合了水稻应对干旱胁迫所采用的调控机制和信号通路的最新研究进展。阐述了干旱条件下水稻发生的适应性变化和分子调控机制。该综述重点介绍了干旱信号的感知和初始传递、关键的下游信号网络如MAPK和Ca途径及其在调节干旱反应中的作用。此外，讨论还扩展到激素信号传导，特别是脱落酸（ABA）在干旱反应中的关键作用，以及抗旱基因的鉴定和基因编辑技术在增强水稻抗旱性方面的应用。通过对这些干旱胁迫调控信号通路的深入分析，本综述旨在为未来水稻抗旱育种和农业生产举措提供有价值的见解和指导。
