Fig. 2. Diatom response to continuous exposure to blue and red light.

A Mean period of oscillation of WT cells for experiments with different ratios of R:B light and the B light controls, bars show mean ± SD (n = 3 independent biological replicates). B Normalized oscillation amplitude for experiments with enhanced light (under B light background of 8 µmol photons m⁻² s⁻¹) at different ratios of R:B light and the controls with B light. Red and blue lines show the linear fits to the experimental data; shaded bands indicate the corresponding 95% confidence intervals. C Normalized Ratio time series for experiments with a 0.75 R:B ratio and B light control of the same intensity.
