title: Role of the tof gene in the production and perpetuation of the lambdadv plasmid.
abstract: A series of lambda derivatives carrying tof mutations were tested for their ability to give rise to plasmid lambda dv. Phages carrying tof mutations that distorted expression of the pRoR-tof-OP operon, were unable to produce lambda dv. Phages carrying an altered tof gene, having only a moderate effect on the same operon, produced unstable lambdadv's. On the other hand, those tof mutants were only the expression of the pLoL-N-exo operon, but not that of the pRoR-tof-OP operon was affected, produced stable lambdadv's.
