Abstract: Nitric oxide (NO) is an important signal molecule in plants, which is critical for regulating plant growth and development. It also indispensably involves in regulating plant tolerance to iron (Fe) deficiency stress. In recent years, many significant progresses have been achieved on the mechanisms underlying the regulation effects of NO on plant responses to Fe deficiency. This review emphasizes the recent advances on NO synthesis and its signal transduction pathway in regulating the responses of plants to Fe deficiency, and the interactive role between NO and other signal molecules in the regulation of Fe deficiencyinduced plant response.
