Abstract excerpt

This study describes an alternative role of the general stress response (GSR) regulated by Sigma B, via the two-component system RsbKY, which is methylated via RsbM, in motility regulation for the peritrichously flagellated, motile, foodborne pathogen Bacillus cereus. Using a set of Sigma B-related mutants, we found reduced surface spreading on low-agar plates for all mutants compared to the WT of B. cereus ATCC...
