Fig. 4 — Power spectrum of the Ratio for experiments that mimic natural fluorescence emission. The thick solid lines correspond to the WT strains, the thin solid lines correspond to the Tc strains, and the dashed lines correspond to the DPH knockout strains. The gray band indicates the period of light oscillation. Panel A shows experiments with far-red light (780 nm), and panel B shows experiments with red light (660 nm). C Differences in collective behavior when using pulsed light versus continuous light: comparison of the peak amplitude of the power spectrum of Ratio under pulsed light (red or far-red, ~140 s) to the peak amplitude under constant light (red or far-red), values close to 1 indicate similar collective behavior, bars represent mean ± SD (n = 3 independent biological replicates). D Peak amplitude of the power spectrum of experiments with constant exposure to B light compared to pulsed red light (~140 s). The abbreviations correspond to the different strains, and data are shown as mean ± SD (n = 3 independent biological replicates).
