Response of the transcriptome to changing light regimes.

Expression dynamics for all genes significantly regulated after the transition from dark to light and vice versa. Overall design: Cultures were first adapted to continuous illumination and to dark for 72 hours. Following the control sampling (time points 0 hours), the cultures' light regime was reversed and cells from both treatments were harvested at 2, 4, 8, and 24 hours after the change.
