Induction of lacI- mutations in Escherichia coli cells after single and split-dose irradiation.

International journal of radiation biology - 1 Jun 1992

Kozubek S, Ryznar L, Horneck G

Abstract excerpt

In the lacI system of Escherichia coli, X-ray mutagenesis follows a linear-quadratic curve with suppression; the survival curve is exponential. Dose fractionation leads to nearly complete repair of premutational lesions during an incubation interval of 3.5 h. Repair starts with a delay of 1.5-2 h...
