title: Cloning of the RHO gene of Escherichia coli.
abstract: The map position of the rho gene on E coil chromosome, as determined by phage P1 generalized transduction, was determined. The gene order is ilv-rho-cya. By Hind III endonuclease shotgun technique, the rho+ gene was cloned into a lambda-Charon 25 vector. The sizing of the restriction endonuclease generated DNA fragments by agarose gel electrophoresis, the heteroduplex analysis of cloned DNA molecules by electron microscope and the demonstration of the synthesis of rho protein by the cloned DNA shows that a functional piece of DNA, containing the entire rho gene of E coli has been cloned.
