Abstract:
Nitric oxide (NO), a signaling free radical, is directly or indirectly involved in virtually all plant physiological processes. Although the enzymatic NO source L-arginine (L-Arg)-dependent nitric oxide synthase (NOS) has been well characterized in animal systems, how NO is enzymatically generated in higher plants remains a subject of debate.
