- Abstract
The gibberellin-inducible rice alpha-amylase gene, RAmy1 A, was demonstrated to be sugar repressed in rice embryos and functional dissection of the promoter of RAmy1 A in relation of its sugar-modulated expression was performed. Gibberellin-response cis-elements of GARE (TAACAAA) and pyrimidine box (CCTTTT) were partially involved in the sugar repression.
