RpoE2 of Sinorhizobium meliloti is necessary for trehalose synthesis and growth in hyperosmotic media.

Microbiology (Reading, England) - 1 Jun 2010

Abstract excerpt

Adaptation to osmotic stress can be achieved by the accumulation of compatible solutes that aid in turgor maintenance and macromolecule stabilization. The genetic regulation of solute accumulation is poorly understood, and has been described well at the molecular level only in enterobacteria. In this study, we show the importance of the alternative sigma factor RpoE2 in Sinorhizobium meliloti osmoadaptation....
