Two cis-acting elements necessary and sufficient for gibberellin-upregulated proteinase expression in rice seeds.

The Plant journal : for cell and molecular biology - 1 Jun 2003

Sutoh Keita, Yamauchi Daisuke

Abstract excerpt

In germinating rice seeds, a cysteine proteinase (REP-1), synthesized in aleurone-layer cells, is a key enzyme in the degradation of the major storage protein, glutelin. The expression of the gene for REP-1 (Rep1) is induced by gibberellins (GAs) and repressed by abscisic acid (ABA). To identify GA-responsive elements in the Rep1 promoter, we developed a transient expression system in rice aleurone cells....
