• A system for induction of synthesis of a-amylase during germination by gibberellin using in-tact seeds, similar to that involving embryo-less half-seeds, was established using a combination of an inhibitor of the biosynthesis of gibberellin, uniconazole, and the rice dwarf mutant, Waito-C (dy mutant). Waito-C is a dwarf mutant in which the biosynthetic pathway to gibberellins is genetically blocked. In the presence of uniconazole, the synthesis of a-amylase by Waito-C during germina-tion was repressed. The repression caused by uniconazole could be overcome by a subsequent treatment with GA_3. The results of activity staining and immunoblotting showed that this repression of the synthesis of a-amylase occurred at the protein level.
