Promoters of Rice Seed Storage Protein Genes Direct Endosperm-Specific Gene Expression in Transgenic Rice

The promoters of genes encoding rice seed storage proteins (glutelin, prolamin, globulin and albumin) were analyzed for their ability to direct rβ-gIucuronidase (GUS) gene expression in transgenic rice plants. All promoters tested could direct endosperm-specific expression of the GUS reporter gene irrespective of variable activities and patterns in the endosperm.
