TABLE 1.
Signal ranges from various strains at 9, 24, or 48 h following the removal of combined nitrogen
| Strain | Signal rangea ± SD (no. of events) |
|
|---|---|---|
| 9 h postinduction | 24 or 48 h postinduction | |
| Wild type | 7.8 ± 1.2 (6) | 7.6 ± 1.5 (5; 24 h) |
| UHM115 (ΔhetN::Ω Spr Smr) | 6.8 ± 1 (4) | 7.5 ± 1.3 (4; 24 h) |
| UHM334 (ΔpatS::Ω Spr Smr) | 0 (6) | NA (6; 24 h) |
| UHM232 (ΔhetC) | 7.4 ± 1.9 (11) | 0 (8; 48 h) |
| UHM224 (ΔhetC ΔpatS::Ω Spr Smr) | 0 (4) | 0.1 ± 0.3 (13; 24 h) |
| UHM225 (ΔhetC ΔhetN::Ω Spr Smr) | 6 ± 3 (6) | 0 (5; 48 h) |
