We describe mutants of Escherichia coli that decrease the plasmid copy number of pBR322 derivatives. One mutant was partially characterized genetically and its mutation, designated pcnB for plasmid copy number, was mapped to approximately 3 rain on the E. coli chromosome. This locus is distinct from
