Recombination properties of P1 dlac.
The P1 dlac prophage plasmid of Escherichia coli K-12 has been utilized as the recipient DNA substrate in experiments with lambda plac5 transduction and with Hfr and F' conjugation. The P1 dlac plasmid does not recombine with lambda plac5 at the elevated levels seen for the F42lac plasmid. Recombination between lambda plac5 and P1 dlac is essentially indistinguishable from recombination between lambda plac5 and a chromosomal lac gene in tems of both level of recombination and recombination pathway (RecBC, RecE, and RecF) dependence. The initiation of recombination between P1 dlac and lac genes from an Hfr or F' donor is severalfold more efficient than it is for a recipient chromosomal lac gene.
