A regulatory trade-off as a source of strain variation in the species Escherichia coli.

Journal of bacteriology - 1 Sept 2004

King Thea, Ishihama Akira, Kori Ayako, Ferenci Thomas

Abstract excerpt

There are few existing indications that strain variation in prokaryotic gene regulation is common or has evolutionary advantage. In this study, we report on isolates of Escherichia coli with distinct ratios of sigma factors (RpoD, sigmaD, or sigma70 and RpoS or sigmaS) that affect transcription i...
