摘要: 一氧化氮(nitric oxide, NO)是植物体内一种重要的信号分子,不仅对植物的生长发育具有重要的调控作用,而且在植物应答缺铁胁迫中同样扮演着关键角色。近年来,有关NO介导的植物缺铁响应调控机制研究取得了一系列重要进展。本文重点针对植物体内NO的合成及其信号转导途径在缺铁胁迫应答中的作用和NO与其他信号分子互作介导植物缺铁响应调控研究进行系统综述与展望,以加深NO在植物缺铁响应调控功能的认识。

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.
