Upon ABA induction, WRKY18 and WRKY40 are first induced and their products could act as early transcriptional effectors to regulate expression of additional ABA-induced genes including WRKY60.
It is possible that upon ABA treatment, WRKY18 and WRKY40 are first induced and cooperative binding of induced WRKY18 and WRKY40 or binding of a WRKY18/WRKY40 heterocomplex to the cluster of W boxes in the WRKY60 promoter is necessary for the subsequent induction of WRKY60.
