FIG 2.
pBS32 induction inhibits growth. Growth curves of strains either treated at time zero with 1 μg/ml MMC or 1 mM IPTG as indicated (solid symbols) or left untreated (open symbols). The following strains were used: WT (3610) (A); DK399 (B); DK297 (C); DK1687 (D); DK451 (E); DK1552 (F); DK1551 (G); DK2063 (H); DK3952 (I); DK3287 (J); DK1634 (Physpank-wkRBSzpdN in an otherwise wild-type strain; gray circles), DK4180 (ΔQII), DK4181 (ΔQIII), and DK4182 (ΔQIV) (K); and DK4112 (L). Shorthand strain features are given in parentheses to aid the reader.
