摘　　要：铁是植物与植物病原物的必需微量元素。土壤中铁含量虽然十分丰富,但基本以不溶的化合物形式存在,不能直接被植物体吸收。为了满足自身生长发育需要,植物在长期的进化过程中,形成了基于还原机制和螯合机制两种铁吸收和铁转运系统。目前对植物铁吸收机制和铁元素在植物-病原物互作的综述相对较少,总结了植物体内铁吸收的两种策略及分子机制,铁在植物细胞内的运输和植物体内响应铁信号的通路,铁对植物免疫反应和病原物致病性的影响等方面的研究进展,以期为植物铁信号途径以及铁在植物-病原物互作中的功能研究提供参考,为作物栽培提供新思路。Iron is an essential trace element for plants and plant pathogens.Although the iron content is rich in soil,it couldn′t be absorbed directly by plants due to the iron existing with the form of insoluble compounds.To supply growth and development,the plants,with long-term evolution process,have formed two iron absorption systems based on the reduction mechanism and chelation mechanism,and iron transport systems.Here,we reviewed the progress of the two strategies and molecular mecha⁃nisms of iron uptake in plants,the transport of iron in plant cells and the pathways in response to iron signaling in plants,the in⁃fluence of iron on plant immune responses,the effect on pathogenicity of pathogens,and the functional mechanism of iron in plant-pathogen interaction.The aim of this review was providing reference for the study of iron signaling pathways in plant and the function of iron in plant-pathogen interaction,providing new ideas for crop cultivation.
