[Survival and repair of single-stranded DNA breaks after gamma-irradiation of Escherichia coli cells depending on the presence of plasmids pKN101 and COIIB-P9].
Plasmids, pKM101 and ColIb-P9, present in an autonomous state in E. coli AB 1157, JC5519, and P3478 cells at the stationary and logarithmic phases of growth, somewhat sensitize the cells to the lethal effect of gamma-radiation and do not influence the radiosensitivity of B/r, Bs-1 gamma R, Bs-1, and W3110 cells. The efficiency of repair of gamma-ray-induced DNA single-strand breaks in AB1157 and P3478 cells containing plasmids is somewhat lower than that in the same non-plasmid strains.
