Figure 8.
A schematic diagram of the involvement of the Esi47 gene in stress and hormone signaling. ABA increases the PLD activity, which in turn suppresses the GA induction of the genes for hydrolytic enzymes including α-amylase. ABA induces the expression of Esi47, PKABA1, RAB, and Hva1 in a PLD-dependent or -independent fashion. Esi47 and PKABA1 suppress the GA induction of the α-amylase gene depending on or independently of PLD activity.
