Function
Transcription factor that binds DNA motifs 5'-CGT[AG](5N)NACG[ACT][AC][AT][ACG][ACT]-3' and 5'-CACG[ACT][AC][AT][AGT][CT]-3' in target genes promoters. Promotes leaf senescence (developmental, light-induced and ABA-induced senescence) and regulates fruit yield and sugar content, probably by establishing abscisic acid (ABA) homeostasis. Activates the expression of senescence and ABA associated genes including NCED1, ABCG40, CYP707A2, SAG113, SGR1 and PAO, by directly binding to their promoters.
