Fig. 1. Expression profiling of the pmrHFIJKLM operon in swarm and vegetative cells of S. typhimurium 14028.

Fig. 1

Luciferase activity of the Ppmr-luxCDABE reporter was measured in cells grown in various agar concentrations with NBG (Nutrient broth, 0.5% glucose) as the basal medium, and normalized with OD620nm. The lower images show that cells are swimming (0, 0.25%), swarming (0.5-1.0%), or non-motile (1.5%) depending on the agar concentration. The normalized luciferase activities (CPS/OD) were averaged from four independent experiments, and the error bars represent the standard deviation.
