Hydrogen Peroxide and Nitric Oxide Signaling Network
Nitric oxide (NO), as a diatomic free radical gas, appears to be involved in development, growth, and biotic/abiotic responses in plants. Also, hydrogen peroxide (H2O2), a reactive oxygen species, has been considered as an important signaling molecule that regulates various physiological and biochemical processes in plants. A large of evidences implied that NO and H2O2 signaling could affect each other at different levels of regulation under common conditions. Meanwhile, NO might have similar kinetics with H2O2. The interaction between NO and H2O2 is complex which has essential role in mediating signaling transduction pathway in plants. This chapter aims to introduce these evidences in our understanding of the roles of NO and H2O2 signaling network in plants and their interaction.
