摘　　要：采用PEG-CaCl2介导的原生质体转化体系,成功地将红色荧光蛋白基因DsRed转入到尖孢镰刀菌古巴专化型4号生理小种B2菌株中。在显微镜下观察连续转接6代的转化子,结果都可以观察到很强的红色荧光,表明DsRed基因在转化的B2菌株中能稳定遗传。通过PCR验证,也表明红色荧光蛋白基因DsRed已经转入到尖孢镰刀菌中。对香蕉的致病力测定结果表明,转化子与野生型菌株B2相比没有明显差异。The report gene coding red fluorescent protein （DsRed） was successfully transferred to the B2 strain of Fusarium oxysporum f. sp. cubense race 4 （Foc4）, by the protoplast-mediated genetic transformation system. After six successive subculture, the strong red fluorecenee could be observed in the obtained transformants under fluorescence microscope. The PCR amplification targeted the DsRed gene confirmed that the DsRed gene had been transferred to the B2 strains of Foe4. Additionally, the pathogeneeity of the transformants didn＇t vary compared with the wild type. In conclusion, the trsanformants with the DsRed gene would do us a favor to observe the pathogenesis of Foc4 in banana plants.
