Abstract

F42 lac recombination with λp lac is normally 20-fold to 50-fold higher than recombination between λp lac and a chromosomal lac gene. Transductional crosses with λp lac and a recombinant plasmid containing the lac operon and F replication functions show only two to four-fold higher recombination than similar crosses with a chromosomal lac gene. Insertion of a BamHI fragment containing the entire tra regulon of F into the mini-F-lac plasmid restores the high level of recombination seen with F42 lac.
