Reactive oxygen species (ROS) are toxic by-products of aerobic metabolism. In plants, they also function as important signaling molecules that regulate biotic and abiotic stress responses as well as plant growth and development. Recent studies have implicated ROS in various aspects of plant reproduction. In male gametophytes, ROS are associated with germline development as well as the developmentally associated programmed cell death of tapetal cells necessary for microspore development. ROS have a role in regulation of female gametophyte patterning and maintenance of embryo sac polarity. During pollination, ROS play roles in the generation of self-incompatibility response during pollen-pistil interaction, pollen tube growth, pollen tube burst for sperm release and fertilization. In this mini review, we provide an overview of ROS production and signaling in the context of plant reproductive development, from female and male gametophyte development to fertilization.

活性氧（ROS）是有氧代谢的有毒副产物。在植物中，它们还起着重要的信号分子的作用，可调节生物和非生物的胁迫反应以及植物的生长发育。最近的研究表明ROS与植物繁殖的各个方面有关。在雄配子体中，ROS与种系发育以及小孢子发育所必需的绒毡层细胞的发育相关的程序性细胞死亡相关。ROS在调节雌性配子体模式和维持胚囊极性中起作用。在授粉过程中，ROS在花粉与雌蕊相互作用，花粉管生长，花粉管破裂以释放精子和受精过程中，在自交配反应的产生中发挥作用。在这个迷你评论中，
