Light-dependent induction of the brlA gene is mediated by FlbA, FlbB, and FlbC. Mycelia of the wild-type and deletion strains were exposed to white light for 60 min and the amount of brlA mRNA was assayed by quantitative RT–PCR. Results are shown as relative to the wild-type samples kept in the dark. The plot shows the mean value and standard error of the mean of at least three independent experiments. Differences between dark and light conditions for the same strain, indicated by * and between different strains under the same conditions by •, are statistically significant according to the Wilcoxon–Mann–Whitney test and a P value <0.05.
