Abstract
The expression and stability of Escherichia coli F-primes in Proteus mirabilis is examined. It is possible to consecutively introduce, and stably maintain, the DNA of several E. coli F-primes in P. mirabilis in the absence of selective pressure for all or some of the plasmids. Additionally, we can recover more than one F-prime from certain P. mirabilis recipient strains which carry DNA derived from several independent matings with E. coli F-prime donors.
摘要
研究了大肠杆菌F-质粒在奇异变形杆菌中的表达和稳定性。在对全部或部分质粒缺乏选择压力的情况下，有可能在奇异变形杆菌中连续导入并稳定维持几种大肠杆菌F-质粒的DNA。此外，我们可以从某些奇异变形杆菌受体菌株中回收不止一种F-质粒，这些菌株携带了与大肠杆菌F-质粒供体进行几次独立交配后获得的DNA。
