Abstract
The ability of some Escherichia coli strains to serve as effective recipients in crosses with donor strains carrying various plasmids (F'lac, F'lac gal Mu, RP4) has been studied. The experiments have shown that there is a locus maintaining the autonomous state of the F-factors. The function of this locus named Fpm ("F plasmids maintenance") is dispensable for both a bacterial cell itself and RP4 plasmid existence in the cell.
摘要
已对一些大肠杆菌菌株在与携带各种质粒（F'lac、F'lac gal Mu、RP4）的供体菌株杂交中作为有效受体的能力进行了研究。实验表明，存在一个维持F因子自主状态的位点。这个名为Fpm（“F质粒维持”）的位点的功能对于细菌细胞本身以及细胞中RP4质粒的存在都是可有可无的。
