摘　　要：病原真菌在侵染植物过程中,往往分泌效应因子增加致病性或被寄主抗病基因识别激发寄主强烈抗性,因此效应因子在植物-病原物的互作中发挥重要作用。CFEM(Common in Fungal Extracellular Membrane)蛋白是真菌中特有的一类位于细胞外膜的蛋白,往往起效应因子的作用。本文综述了植物病原真菌CFEM蛋白家族的结构特点,在不同物种中的表达和定位,CFEM蛋白对真菌胞内铁吸收和生长发育方面的调控作用,抑制寄主免疫反应和促进真菌寄生的作用机制以及CFEM蛋白起源和进化过程等方面的研究进展,同时对目前CFEM蛋白研究有待阐明的问题进行了讨论并展望了未来的研究方向。本文将有助于人们进一步了解植物-病原真菌互作分子机理以及CFEM蛋白的致病机理,为培育作物抗病品种和制定植物真菌病害防控策略提供参考。In the process of infecting plants, pathogenic fungi may often secrete effectors to increase pathogenicity, or conversely, be recognized by the host to trigger resistance. Hence, such effectors are crucial for the well-being of a plant at time of a pathogenic intrusion. As an effector, CFEM(common in fungal extracellular membrane) protein is found only in the outer membrane of a fungal pathogen. This article reviews the origin, evolution, growth, development, structural characteristics,expressions and localization in different species, and intracellular iron absorption regulations of the CFEM protein family as well as the host immunology and infection-promoting factors associated with the proteins in the phytopathogens. Some of the yet-to-be-clarified issues on the molecular mechanisms and plant-pathogen interactions relating to CFEM proteins are discussed to facilitate the cultivation of disease-resistant plants and the development of ecologically friendly disease control strategies on crops.
