Hybrid plasmid DNA cloned in Escherichia coli undergoes deletions when returned to competent Bacillus subtilis, even in defined restriction and modification mutants of strain 168. We have isolated a mutant of B. subtilis MI112 which is stably transformed at high frequency by chimeric plasmid DNA propagated in E. coli.
克隆于大肠杆菌中的杂种质粒DNA,即便导入枯草芽孢杆菌168株特定的限制与修饰突变体中,当再导入感受态枯草芽孢杆菌时仍会发生缺失。我们已分离出枯草芽孢杆菌MI112的一个突变体,它能被在大肠杆菌中增殖的嵌合质粒DNA以高频稳定转化。
