| 摘 要： | 植物被病原体感染后，植物体内活性氧产量急剧增加，这一现象被称为氧爆。活性氧族包括如单线态氧^1O2、超氧阴离子自由基O2^-、氢过氧自由基HO2·、过氧化氢H2O2、羟自由基·OH等。与ROS关系密切的一氧化氮，属于活性氮族。ROS和NO参与植物生长发育调控和对环境胁迫的应答反应，特别是在对抗外来病原体的入侵的防卫过程中发挥了重要作用。本文主要讨论ROS和NO在植物与病原体相互作用中发挥的作用。

| Abstract: | Production of reactive oxygen species （ROS） during host-pathogen interactions is termed -oxidative burst. The most important ROS include singlet oxygen （^1O2）, superoxide anion O2, the hydroxyperoxyl radical （HO2·）, hydrogen peroxide （H2O2） and the hydroxyl radical （·OH）. Nitric oxide （NO）, which has a close relation with the ROS, belongs to reactive nitrogen species （RNS）. The ROS and NO are involved in regulation of plant growth and development and in responses to environmental stress, and play an important role especially in their defense against pathogenic invasion. Different roles of the ROS and NO in host-pathogen interactions are discussed. |
