Cotton leaf curl virus (CLCuV) promoter and its use

摘要

The present invention is directed to a cotton leaf curl virus (CLCUV) bi-directional promoter, a method of expressing a heterologous gene in various plant tissues at a high level using the cotton leaf curl virus bi-directional promoter, and an AC2 protein factor from CLCuV genome to improve the expression level of the coat protein-coding gene promoter in the bi-directional promoter. The expression of a heterologous gene in plants is improved by using the materials and methods of the present invention.
