Selection for defective reversion induction, after UV treatment of E. coli K 12, yielded uvm mutants. These mutants exhibited highly reduced or no UV mutability for all loci tested although they were moderately and normally mutable by X-rays and EMS, respectively. Uvm mutations confer only a slight
Uvm mutants of Escherichia coli K12 selected for defective UV reversion induction have previously been reported to differ considerably from the UV-reversion-less recA and lexA mutants with regard to survival or mutagenic response to UV, X-rays and alkylating agents. In the present study, the phenoty
