Reactive oxygen species (ROS) play an essential role in the regulation of seed dormancy, germination, and deterioration in plants. The low level of ROS as signaling particles promotes dormancy release and triggers seed germination. Excessive ROS accumulation causes seed deterioration during seed storage. Maintaining ROS homeostasis plays a central role in the regulation of seed dormancy, germination, and deterioration in crops. This study highlights the current advances in the regulation of ROS homeostasis in dry and hydrated seeds of crops. The research progress in the crosstalk between ROS and hormones involved in the regulation of seed dormancy and germination in crops is mainly summarized. The current understandings of ROS-induced seed deterioration are reviewed. These understandings of ROS-dependent regulation on seed dormancy, germination, and deterioration contribute to the improvement of seed quality of crops in the future.
活性氧（ROS）在植物种子休眠、萌发和劣变的调控中起着至关重要的作用。作为信号分子的低水平ROS促进休眠解除并触发种子萌发。过量的ROS积累会导致种子在储存期间劣变。维持ROS稳态在作物种子休眠、萌发和劣变的调控中起着核心作用。本研究重点介绍了作物干燥种子和水合种子中ROS稳态调控的当前进展。主要总结了ROS与参与作物种子休眠和萌发调控的激素之间相互作用的研究进展。综述了目前对ROS诱导种子劣变的认识。这些对ROS依赖的种子休眠、萌发和劣变调控的认识有助于未来作物种子质量的提高。
