FIG. 3.
The kinetics of induction of the rpoS, otsB, proP, and ompC genes after shock with 0.3 M NaCl. RNA preparations isolated in the experiment shown in Fig. 2 were used to measure the expression of the rpoS, otsB, proP, and ompC genes at the indicated time points as described in Materials and Methods. (A) Normalized mRNA levels for the rpoS and otsB genes; (B) data for the proP, ompC and gnd genes for the first 20 min after the shock with 0.3 M NaCl. These panels also include the results for the proV gene, copied from Fig. 2. (C) Data for the rpoS, otsB, proP, ompC, and gnd genes for the 20 to 60 min after the osmotic shock.
