Nitric oxide is a bioactive and signal transmitting molecule that does not only directly exert physiological regulations on many life activities of plants such as germination, growth and senescence but also participates in the adapting of plants to environmental stresses working as the key signal carrier in defense response, such as drought stress, heat and chilling stress, salt stress, UV-B radiation, and ozone exposure, heavy metal, mechanical stress and disease resistance. Nitric oxide presents synergistic effects with phytohormones in physiological regulation and signal transmission, such as Ethylene, Abscisicacid, Saliccylicacid, indole-3-acetic acid and cytokinin, it is one of nitric oxide regulation mechanisms for plants to resorts to phytohormones to play its physiological functions. In present, it is an important study to investigate endogenous NO mechanisms for plants physiological regulation and signal transmission.
