The mechanism of the PRC in plants. (A) A PRC was simulated by monitoring the phase of peaks of LUX expression after light pulses of 1 h duration given on the second day in darkness after 12L:12D entrainment. Data points were taken from Covington et al (2001) for red light pulses. (B–D) The simulated profiles of LUX mRNA (blue) and LHY protein (magenta) with (dashed lines) or without (solid lines) light pulses given at indicated times (arrow)—at 18 h (B), 12 h (C) or at 18 h for a simulated mutant without an acute light response in LHY transcription (D; parameter q1=0). Time 0 refers to the beginning of the second day in darkness.
