title: Role of Rec pathways on sensitivity of Escherichia coli to near-ultraviolet and visible light.
abstract: In Escherichia coli lack of the RecRC or RecF pathway is found to cause sensitivity to near-ultraviolet and visible light. Resistance to this light is restored in the RecBC-defective strain carrying either the sbcB (Rec+) or xonA (Rec-) mutation. The sensitivity, therefore, is not found to correlate with the degree of recombination proficiency as measured by genetic crosses.
