FIG. 4.
Temporal transcriptional activity of ERES region genes in the wild-type and Ralp3 mutant backgrounds. Growth phase-dependent luciferase activity was measured in THY medium under a 5% CO2-20% O2 atmosphere at 37°C. Growth was monitored over time by measuring the culture OD600 (left panels). Luciferase activity is expressed in relative light units (RLU) (right panels). The results of one representative experiment out of five independent experiments are shown. (A) Activity of epf (transcriptional profile of epf-luc); (B) activity of sagA (transcriptional profile of sagA-luc); (C) activity of eno (transcriptional profile of eno-luc).
