The adaptation of Rhizobium leguminosarum bv. phaseoli to oxidative stress and its overlap with other environmental stress responses
Article Abstract:
The response of the symbiotic nitrogen-fixing bacterium Rhizobium leguminosarum biovar phaseoli to environmental stress is analyzed to understand the bacterium's ability to adapt to and survive in adverse soil conditions. The bacterium is also studied for its ability to form nitrogen-fixing symbioses with leguminous plants. The oxidatively stressed R. leguminosarum cells' capacity to acquire resistance to osmotic, heat-shock, starvation and other environmental stresses is also investigated.

Evidence for cell-density-dependent regulation of catalase activity in Rhizobium leguminosarum bv. phaseoli
Article Abstract:
A study conducted to analyze the catalase activity of Rhizobium leguminosarum bv. phaseoli shows that the induction and further repression of catalase activity in exponential cultures is dependent on cell density, and that growing cells are less resistant to catalyse activity than are stationary cells. The accumulation of extracellular molecules that control catalase in R. leguinosarum produces phenoma similar to that of the cell-density regulated bacteria.

A role for DNA supercoiling in the regulation of the cytochrome bd oxidase of Escherichia coli
Article Abstract:
Research reveals that cytochrome bd oxidase of Escherichia coli is encoded by the cydAB operon and its regulation is mediated by DNA supercoiling in response to stress conditions.
