[Detection, on the Escherichia coli chromosome, of the locus necessary to maintaining an autonomous state of sex factor F'lac].
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.
