TABLE 2.
SigF-dependent gene expression (P < 0.01) in M. smegmatis grown in LB-Tween batch cultures
Mean growth rate μ, h−1, ± SD (OD600) | SigF-dependent genes (P < 0.01) | No. of genes with expression in ΔsigF straina: |
|
---|---|---|---|
Reduced (ratio of <0.5) | Increased (ratio of >2) | ||
0.25 ± 0.02 (0.4 ± 0.05) | 218 | 62 (11) | 3 (3) |
0.07 ± 0.01 (4.0 ± 0.2) | 239 | 122 (71) | 2 (2) |
The ratio is that of ΔsigF strain to wild-type gene expression. Genes unique to the growth phase are in parentheses.
