L. monocytogenes genes with significantly higher expression in the wild-type versus the ΔsigB strain under osmotic and stationary-phase stresses
| Changea (fold) | No. of genes with statistically significant higher expression under:
|
|||
|---|---|---|---|---|
| Stationary phase stress | Osmotic stress (0.5 M KCl) | Stationary-phase and osmotic stress | Stationary-phase or osmotic stress | |
| ≥1.5 | 41 | 51 | 37 | 55 |
| ≥2.0 | 37 | 44 | 30 | 51 |
a
Change was calculated by SAM based on microarray data (see Materials and Methods) and equals the average wild-type spot intensity divided by the average mutant spot intensity for two separate arrays from each of two replicate RNA isolations.
