FIG. 2.
Comparison of differentially expressed genes between B. cereus ATCC 14579 (WT) and the sigB and rsbY deletion mutants. The numbers of genes that are differentially expressed between the parental strain (WT) and the rsbY and sigB mutants upon a heat shock to 42°C for 10 min are indicated in the circles. The black overlapping area indicates that the same genes were identified as being differentially expressed in both the sigB and the rsbY deletion mutants under the indicated conditions. Twenty-four genes were also upregulated upon a heat shock, and these genes form the σB regulon of B. cereus.
