【目的】炭疽病是油茶的主要病害,导致巨大的经济损失。果生炭疽菌是油茶炭疽病优势致病菌。对果生炭疽菌的转录因子CfHac1的结构域进行分析,为进一步解析转录因子CfHac1调控病菌致病的分子机制奠定基础,对挖掘油茶炭疽病防控新途径具有重要的理论意义。【方法】采用点突变技术构建转录因子CfHac1结构域缺失载体,通过PEG介导法将该回补载体转化至CfHAC1基因完全缺失突变体的原生质体中,通过博来霉素抗性和荧光筛选获得结构域缺失回补菌株,进一步研究BRLZ结构域在果生炭疽菌中的生物学功能。【结果】结果发现转录因子CfHac1含有一个碱性亮氨酸拉链结构域（BRLZ）,该结构域包含58个氨基酸残基;与野...

Objective: Colletotrichum fructicola is a major pathogen causing anthracnose on Camellia oleifera, and leads to substantial losses annually. The domain analysis of transcription factor CfHac1 will help us understanding the CfHac1-regulated pathogenic mechanism of the pathogen and provide new insights to control this disease. Method: We constructed the domain deletion vector using point mutation technology and introduced it into the ΔCfhac1 mutant through the PEG-mediated protoplast transformation. The strains were selected by bleomycin and flu...
