Abstract
Summary Salmonella typhimurium recombinants have been constructed which have acquired UV-induced mutability. Such recombinants were obtained after transfer of plasmid F′126 from E. coli. UV-mutability was acquired by UV-stable Salmonella as a nonselective marker after selection of trp + marker in 2.5% of the cases. Possible deficiency in UV-stable Salmonella of the umuC gene is discussed.Keywords
