[Lysogenic conversion induced by phage phi 80. II. Mapping of the cor locus].

The cor locus determines lysogenic conversion of the lambdoid phi 80 phage. The cor locus was cloned from phi 80, phi 80pt1, phi 80pt0, phi 80pt4A and lambda hy51 DNAs in the pBR322 plasmid. According to the physical and genetic data, the cor locus was located on the genetic map of phi 80 bacteriophage at the 40.3 divided by 43.5% lambda. It is closely linked to the gene 13 of phi 80 phage and has a position similar to that of lom gene of lambda phage.
