The abscisic acid (ABA) response promoter complexes (ABRCs) of the HVA1
and HVA22 genes have been shown to confer ABA-induced gene expression in
cereals. A barley basic domain/Leu zipper (bZIP) transcription factor, HvABI5, is
able to recognize ABRCs in vitro in a sequence-specific manner and to transactivate
ABRC-
