Effects of copy number of an octopine synthase enhancer element and its distance from the TATA box on heterologous expression in transgenic tobacco

Abstract

The relationship among motif copy number, its distance from the TATA box and expression level was analyzed in transformed tobacco plants. Single or multiple copies of octopine synthase (ocs) enhancer elements from the ocs promoter were linked to the minimal ocs promoter and a β-glucuronidase (GUS) reporter gene, then transformed stably into tobacco… (More)
