Promoters of rice seed storage protein genes direct endosperm-specific gene expression in transgenic rice

Abstract

The promoters of genes encoding rice seed storage proteins (glutelin, prolamin, globulin and albumin) were analyzed for their ability to direct β-glucuronidase (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.
