[UV-mutagenesis in Bacillus subtilis. VII. Mutability of recA, recB and recF strains].

Abstract

UV-light induces reversions to threonine-independence in BD170 Rec+ cells, and does not induce them in isogenic strain BD241 recF. Reversions to methionine-independence are induced in cells GSY1028 recB, and are not in isogenic strain GSY1025 recA. It is possible to construct, with the use of transformation, a viable strain carrying mutations recF and su… (More)
