Abstract
The present invention provides new gene expression regulatory DNA. This gene expression regulatory DNA comprises a promotor region derived from the barley D-hordein gene enabling the expression of a desired gene, and a regulatory region for regulating the expression of said gene based on said promoter region. This regulatory region consists at least of an activating region to activate the expression of said gene and a suppressing region to suppress the same. Use of this gene expression regulatory DNA enables controlling as desired the expression of gene within a plant cell such as barley.
