Efficiency of transformation of E. coli wild-type and ppGpp0 strains with lambdoid plasmids
| Plasmid | Efficiency of transformation (transformants per 1 μg of plasmid DNA)a |
|
|---|---|---|
| Wild type (MG1655) | ppGpp0 | |
| p933Wcmr | (1.5 ± 0.06) × 104 | (1.7 ± 0.04) × 104 |
| p22cmr | (0.9 ± 0.05) × 104 | (0.8 ± 0.07) × 104 |
| p27cmr | (2.3 ± 0.14) × 104 | (2.1 ± 0.03) × 104 |
| p32cmr | (1.2 ± 0.11) × 104 | (1.1 ± 0.08) × 104 |

Mean values from 3 experiments ± SD are presented. No statistical significance (P > 0.05 in t test) in differences between results obtained for all tested pairs (wild type versus ppGpp0) was found.
