摘　　要：铁是植物生长所必需的微量元素之一,由于土壤的理化性质以及铁元素含量的差异,导致植物对铁的吸收效率较低,而在一些铁污染的土壤中,铁却对植物产生严重的毒害作用。本文通过对植物吸收转运铁的分子机制及其相关基因的功能进行综述,以期在植物缺铁胁迫和铁毒害的基因调控转录机制方面提供一定的理论依据,对后期培育耐受缺铁胁迫或铁毒害的植物有一定的参考意义。Iron is one of the essential trace elements for plant growth.Due to the difference of soil physical and chemical properties and iron content,plants have low absorption efficiency of iron.However,in some iron contaminated soil,iron has a serious toxic effect on plants.In this paper,the molecular mechanism of iron uptake and transportation in plants and the function of related genes were reviewed in order to provide a theoretical basis for gene regulation and transcription mechanism of iron deficiency stress and iron toxicity in plants,and provide a certain reference for the cultivation of plants tolerant to iron stress or iron toxicity in the later stage.

关 键 词：缺铁胁迫 铁毒害 关键功能基因 植物
