title: The hunt for plant nitric oxide synthase (NOS): is one really needed?
abstract: 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.
