Abstract

A method of and plasmids for producing specific gene expression in the guard cells of plants. In particular, 5' transcriptional regulatory promoter regions are provided for guard cell specific expression. In addition, methods for preparing an expression cassette, plasmids, and the use of the cassettes and plasmids to produce transgenic plant cells and plants are described.
