Contributions of individual σB-dependent general stress genes to oxidative stress resistance of Bacillus subtilis.

abstract：:At specific times in the cell cycle, the bacterium Caulobacter crescentus assembles two major polar organelles, the flagellum and the stalk. Previous studies have shown that flbT mutants overproduce flagellins and are unable to form chemotaxis swarm rings. In this paper, we report alterations in both the stalk and the...
