Novel role of mfd: effects on stationary-phase mutagenesis in Bacillus subtilis.

Abstract excerpt

Previously, using a chromosomal reversion assay system, we established that an adaptive mutagenic process occurs in nongrowing Bacillus subtilis cells under stress, and we demonstrated that multiple mechanisms are involved in generating these mutations (41, 43). In an attempt to delineate how these mutations are generated, we began an investigation into whether or not transcription and transcription-associated...
