Blue and Red Light Modulates SigB-Dependent Gene Transcription, Swimming Motility and Invasiveness in Listeria monocytogenes
Figure 6
Effect of incubation temperature and light on swimming motility.
Semi-solid BHI agar (0.3%) plates were inoculated with 2 µl of mid-log cultures (OD600 ∼0.7) of wild type, Δlmo0799 and ΔsigB mutants. Incubation was for 18 h at temperatures and light conditions as indicated in the figure. (B) shows the effect of blue light, the result for red light was identical, (F) shows the means and standard deviations of the colony diameters from three independent experiments.
