植物依靠先天免疫系统来保护自己免受病原体的攻击。活性氧（ROS）和一氧化氮（NO）在植物抗病机制的激活中起着关键作用。丝裂原活化蛋白激酶（MAPK）级联是真核生物中普遍存在的信号转导模块，在植物天然免疫中发挥重要作用。自由基（ROS和NO）与MAPK级联反应的关系一直存在争议。最近，我们发现MAPK级联参与了自由基爆发的调控。在这里，我们讨论了响应病原体攻击的氧化和NO爆发的调节机制，以及MAPK信号传导和自由基爆发之间的串扰。
Plants rely on the innate immune system to defend themselves from pathogen attacks. Reactive oxygen species (ROS) and nitric oxide (NO) play key roles in the activation of disease resistance mechanisms in plants. The evolutionarily conserved mitogen-activated protein kinase (MAPK) cascades are universal signal transduction modules in eukaryotes and have been implicated in the plant innate immunity. There have been many disputations about the relationship between the radicals (ROS and NO) and MAPK cascades. Recently, we found that MAPK cascades participate in the regulation of the radical burst. Here, we discuss the regulatory mechanisms of the oxidative and NO bursts in response to pathogen attacks, and crosstalk between MAPK signaling and the radical burst.
