Spatiotemporal dynamics of cellular oscillators in a CCA1::LUC plant under continuous light.
2-h dark-pulses were applied at t = 6, 30 and 54 h. (a) Sequence of bioluminescence images of the plant shown with 4-h interval for 3 days duration. (b) Sequence of phase images corresponding to (a), where the phase Φ was computed from the bioluminescence signal. (c) Phase images with 24-h interval for 5 days duration. (d) Time evolution of the phase distribution of the whole plant shown in (b). Red and blue colors indicate high and low densities of the phase distribution, respectively. The black lines indicate the timings, at which the 2-h dark-pulses were applied. (e) Time evolution of the circular statistics R. The black line corresponds to R computed for the whole plant, whereas the non-black lines indicate R for individual leaves.
