摘　　要：叶霉菌(Cladosporium fulvum)是番茄(Solanum lycopersicum)叶霉病致病真菌,严重地威胁着番茄生产;二者互作遵循"基因对基因"假说,是目前研究植物与病原菌互作模式系统。本文简要地回顾了番茄叶霉菌和抗性基因(Cf)研究历史;概述了叶霉菌侵染特征、效应因子的类型、功能和特性;对番茄Cf基因的类型、定位、进化、结构和功能研究进展加以综述,特别是对Cf/Avr互作的分子机制、信号转导和抗性基因自激活等最新研究成果加以重点阐述;同时,对今后番茄抗叶霉病研究所面临问题、研究热点和解决策略进行了讨论。以期为番茄抗叶霉病或植物抗真菌病研究提供一些有用信息。Cladosporium fulvum （syn. Passalora fulva） is a fungal pathogen that causes tomato （Solahum lycopersicum） leaf mold disease, and threat commercial tomato production seriously. The C. fulvum-tomato interaction strictly fits the gene-for-gene principle, and has become a model system for studying plantpathogen interaction. In this paper, the research history of C. fulvum and Cf genes resistant to C. fulvum were reviewed. Subsequently, the current progresses were summarized on the infection behaviors of C. fulvum as well as the types, characters and functions of effector proteins derived C. fulvum. Meanwhile, the research progresses were also reviewed on the types, evolution, structures and functions of Cf genes. Especially, the recent progresses were emphatically reviewed on the molecular mechanism of Cf/Avr interaction, signal transduction depended on Cf/Avr and the autoactivity of Cf genes. Finally, we discussed the faced questions, research hotspots and strategies on the resistance of tomato to C. fulvum so as to provide some available information for further investigating tomato＇s resistance to C. fulvum or plants＇ resistance to fungus.
