Abstract excerpt
Antimutator strains are strains that have a lower mutation rate than the wild-type strain. We have reexamined the properties of one reported antimutator strain of Escherichia coli, termed mud [Mol. Gen. Genet. 153 (1977) 87]. This strain contains a temperature-sensitive mutation in the purB gene, leading to adenine-dependent growth at higher temperature. When grown at permissive or semi-permissive temperature in...
