Hormonal control of enzyme synthesis: on the mode of action of gibberellic Acid and abscisin in aleurone layers of barley.

abstract：:Some key carotenogenic genes (crts) in Dunaliella bardawil are regulated in response to salt stress partly due to salt-inducible cis-acting elements in their promoters. Thus, we isolated and compared the ζ-carotene desaturase (Dbzds) promoter with other crts promoters including phytoene synthase (Dbpsy), phytoene desa...
