The circadian clock not only coordinates plant growth with daily environmental changes but also interacts with endogenous hormonal pathways, such as abscisic acid (ABA) signaling, to balance growthabiotic stress responses. Although the feedback network between the circadian systemABA pathway has been well established, the regulatory relationship between the ABA receptor PYRABACTIN RESISTANCE 1-LIKE (PYL) familythe clock remains largely unclear,the understanding of how ABA signaling feeds back to modulate the clock is still limited. Here, we show that the null mutants of TIME FOR COFFEE (TIC)CIRCADIAN CLOCK ASSOCIATED 1/LATE ELONGATED HYPOCOTYL (CCA1/LHY), which are core components of the circadian morning complex (MC), display hypersensitivity to ABA during seed germination. Mechanistically, the MC could directly bind to the promoters of PYL4, PYL5,PYL6 to repress their transcription at dawn, which may contribute to the attenuation of ABA signal transduction. Furthermore, ABA could induce TIC expression,TIC is required for transferring ABA signalsa coherent circadian rhythm. Taken together, these findings suggest that the MC may function as a dawn-specific integrator, linking ABA signaling with the circadian core oscillator, hence offering new insightshow plants coordinate hormonaltemporal regulation.
