Important Steps Involved in the Hormonal Regulation of α-Amylase in Aleurone Cells.

A repressor, SLN1, and an activator, GAMyb, are essential components in the GA signaling pathway leading to the induction of α-amylase. An alternative route from ABA to the site of interaction with the GA signaling cascade (represented by X) is proposed to indicate that the transcriptional induction of PKABA1 is sufficient, but not necessary, to block α-amylase expression.
