Abstract
Three recombinant plasmids, resulting from recombination between an R plasmid of the FI incompatibility group and the F of HfrH, were introduced in a temperature-sensitive dnaA mutant to isolate Hfr-type-donors. All of the temperature-insensitive clones isolated from two of the three recombinant plasmids had the same origin and transfer pattern as the parental HfrH strain.
摘要
三个重组质粒由FⅠ不相容群的R质粒与HfrH的F因子重组而成，将它们导入温度敏感型dnaA突变体中以分离Hfr型供体。从三个重组质粒中的两个分离得到的所有温度不敏感克隆，都具有与亲本HfrH菌株相同的原点和转移模式。
