Stress and survival of aging Escherichia coli rpoS colonies

Genetics. 2004 Sep;168(1):541-6. doi: 10.1534/genetics.104.028704.

Abstract

In Escherichia coli, the expression of the RpoS regulon is known to be crucial for survival in liquid cultures during stationary phase. By measuring cell viability and by transcriptome analysis, here we show that rpoS cells as well as wild-type cells survive when they form colonies on solid media.
