在植物中,程序性细胞死亡(PCD)是调节生长和发育的多个方面的重要机制,以及在响应环境胁迫和病原体攻击期间去除受损或感染的细胞。在生物和非生物胁迫下,植物细胞表现出一氧化氮(NO)的快速合成和活性氧(ROS)的平行积累。通常,这些反应会触发 PCD 过程,从而导致植物细胞的内在执行。越来越多的证据表明,NO 和 ROS 在 PCD 中发挥着关键作用。这些氧化还原活性小分子可以独立或协同地触发细胞死亡。在这里,我们总结了在不同信号引起的过敏反应、叶片衰老和其他类型的植物 PCD 中 NO 和 ROS 信号串扰的最新进展。
In plants, programed cell death (PCD) is an important mechanism to regulate multiple aspects of growth and development, as well as to remove damaged or infected cells during responses to environmental stresses and pathogen attacks. Under biotic and abiotic stresses, plant cells exhibit a rapid synthesis of nitric oxide (NO) and a parallel accumulation of reactive oxygen species (ROS). Frequently, these responses trigger a PCD process leading to an intrinsic execution of plant cells. The accumulating evidence suggests that both NO and ROS play key roles in PCD. These redox active small molecules can trigger cell death either independently or synergistically. Here we summarize the recent progress on the cross-talk of NO and ROS signals in the hypersensitive response, leaf senescence, and other kinds of plant PCD caused by diverse cues.
