| Abstract |
AtC401 is an Arabidopsis homolog of PnC401 that is related to photoperiodic induction of flowering in Pharbitis nil. These genes show free-running rhythms. To study the free-running rhythm of AtC401, we fused a firefly luciferase reporter to the AtC401 promoter and transformed it into Arabidopsis plants. The observed bioluminescence oscillated under continuous light and continuous dark only with sucrose supplementation. The free-running period of bioluminescence was temperature-compensated between 22 degrees C and 30 degrees C. Light-pulse experiments under continuous darkness produced a phase-response curve typical of circadian rhythms. We conclude that rhythmic expression of AtC401 is controlled by a circadian oscillator.
