A BRASSICA REGULATORY SEQUENCE FOR ROOT-SPECIFIC OR ROOT-ABUNDANT GENE EXPRESSION

摘要

The present invention is directed to an isolated promoter element that exhibits root abundant expression in Brassica sp. The promoter element has particular utility in driving the transcription of heterologous structural proteins that confer disease immunity or resistance to disease susceptible roots. The word 'disease' encompasses any adverse condition caused to a plant by an organism other than itself, such as fungi, bacteria, and insects. Plasmids incorporating the promoter are disclosed.
