Nitric oxide (NO) production is associated with many physiological situations in plants, and NO is a key signaling molecule throughout the lifespan of a plant. The complexity of the underlying signaling events are just starting to be unraveled. The basis for nitric oxide signaling, the production of the signaling molecule itself, is far from understood in plants. While in animals, three homologous NO synthases (NOS) isoforms have been identified, yet in higher plants no corresponding enzymes are known so far. More than half a dozen NO productive reactions have been observed in plants but only few of them have been thoroughly investigated. It remains to be elucidated how these parts act together to form the sophisticated NO signaling network observed in plants.
一氧化氮（NO）的产生与植物中的许多生理情况有关，而 NO 是植物整个生命周期中的关键信号分子。目前，这些信号事件的复杂性才刚刚开始被揭示。在植物中，对于一氧化氮信号转导的基础，即信号分子本身的产生，人们还远未了解。虽然在动物中已经鉴定出三种同源的一氧化氮合酶（NOS）同工型，但到目前为止，在高等植物中还没有发现相应的酶。在植物中已经观察到了六种以上产生 NO 的反应，但只有其中少数几种得到了深入研究。目前仍不清楚这些部分如何协同作用，形成植物中观察到的复杂的 NO 信号网络。
