Analysis of rpoS knockout mutants of bacteria K-12 strain MG1655 cells in exponential phase. RpoS, an alternative sigma factor and a stress response regulator, is a major regulator of genes required for stationary phase adaptation. Results provide insight into the role of RpoS in exponential phase.

Analysis of derivatives of strain MG1655: wild-type, fur mutant, and wild-type with added FeSO4, induced to overexpress RyhB. RyhB is a noncoding RNA regulated by the Fur repressor protein. Results suggest that RyhB plays a major role in the regulation of iron metabolism.
