xct Mutants Display Short Period Rhythms for Multiple Circadian Clock Outputs.

After entrainment to 12:12 LD cycles for 6 d, CCR2_pro:LUC displays rhythmic short-period expression in xct mutants held in constant darkness (A), constant red light (B), and constant blue light (C). Similarly, xct mutants demonstrate short period leaf movement rhythms in constant white light (D). Each data point is the average of 8 to 36 seedlings for CCR2_pro:LUC and 42 to 80 cotyledons for leaf movement analysis, and error bars represent se. Error bars are presented only on every 12th data point in (A) for clarity. Shaded and closed or open and shaded bars on the x axis represent subjective day and subjective night, respectively.
