Abstract:
BBX19, a transcription factor with two B-Box motifs, is a clock output component that functions as a flowering time checkpoint by physically interacting with CO and depleting the CO pool required for FT activation. The integrity of the Box1 motif is necessary for the functionality of BBX19.
