FIGURE 3.
Relative intracellular levels of c-di-GMP measured with the transcriptional PcdrA-lacZ reporter. The levels of c-di-GMP in PAK carrying the vector control were set to 1. At least three independent experiments were performed. Error bars represent the standard deviations, and statistically significant changes are indicated (∗∗P < 0.01, Student’s t-test).
