✦ Synopsis

Measurements of UV sensitivity of wildtype cells (wt) and UV senistive mutants of E. coli and P. mirabilis suggest that the increased sensitivity of P. mirabilis (wt) is due either to incomplete repair of DNA lesions or to additive lethality probably as a result of UV induction of defective phage(s) present in P. mitabilis (Taubeneck, 1967). Direct estimates of the rate of pyrimidine dimer excision and a comparison of the UV reactivation capacity of E. coli and P. mirabilis for the temperate phages lambda and pi 1, respectively, support this conclusion.

The expression of plasmid R46-mediated recovery and mutagenic function (s) was studied in P. mirabilis, which is normally either weakly or non-mutable after UV exposure. The plasmid was found to confer on P. mirabilis enhanced UV resistance as well as UV-induced mutability for various types of forwa
