title: [Phenomenon of w-reactivation in plasmids].
abstract: An analysis of the action of the bacterial repair system on the UV-irradiated pMB9 plasmid has been carried out. It has been shown that the UV-irradiated plasmid is repaired in the bacteria similarly to the DNA of bacteriophage (lambda): the effectiveness of the UVR-system is lowered two-three times, and the postreplicativing REC system acts only at low doses of the UV-light. The phenomenon of omega-reactivation is observed both with plasmid and phage DNAs.
