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

Replication of mini-plasmids derived from bacteriophage P1 and naturally existing plasmids F, R1, R6K and RK2 in otherwise isogenic relA+ and reLk Escherichia coli strains during amino acid starvation and limitation was investigated. Since it was previously demonstrated that inhibition of DNA synthe
