| 摘 要： | 利用PEG方法，将含有潮霉素抗性标记的质粒pCB1003转化毛壳霉原生质体,并在高于毛壳霉敏感的潮霉素浓度下筛选转化子。转化率达1～2个转化子/μg质粒DNA。以潮霉素抗性的毛壳霉转化子的基因组DNA为模板进行PCR扩增及其产物的Southern杂交。结果表明，潮霉素抗性基因已整合入毛壳霉染色体。稳定性试验表明，所获得的转化子可通过有丝分裂稳定传代。

| Abstract: | Genetic transformation has been achieved by incubatingprotoplasts from Chaetomium globosum with plasmid PCB1003. The efficiency was 1-2 transformants/μg vector DNA. Protoplasts were produced by treating 14-hour old mycelium of Chaetomium globosum with 10 mg/mL lysozyme. Chaetomium globosum growth was inhibited completely when the medium contained 150 μg/mL hygromycin B. Integration of hph gene was verified by PCR and PCR product hybridization analysis. There was no evidence of mitotic of hygromycin B resistance in the transformants. |
