Intensities of constant light conditions are presented in μE (μmol m−2 s−1). CCR2pro:LUC activity was determined in constant darkness (DD), constant red light (cRL), constant blue light (cBL), or the combination of constant red and blue light (cR+BL). Cotyledon movement rhythms (LMRA) were monitored in constant white light. xct mutants transformed with a genomic copy of XCT under the control of the native XCT promoter (XCTpro:XCT) or the globally expressed cauliflower mosaic virus 35S promoter (35Spro:XCT) were assayed in the T1 generation, with similar rescued periods observed in resulting T2 and T3 families. ND represents data not determined; se is the standard error for (n) individuals.
