EXPRESSION CASSETTE AND PLASMIDE FOR CLOSE-CELL-SPECIFIC EXPRESSION AND THEIR USE FOR THE PRODUCTION OF TRANSGENIC PLANT CELLS AND PLANTS

摘要

There is described an expression cassette and plasmids containing an expression cassette, which contains the transcriptional regulatory starter region for a guard cell specific gene expression. In the expression cassette is contained the guard cell promoter having the sequence Seq. ID No: 1. The starter region in the expression cassette ensures a guard cell specific gene expression and causes no expression in mesophyllic cells or epidermal cells of the leaves of plants. There is also described the preparation of the expression cassette and plasmids containing this expression cassette. Also described is the use of the expression cassette and plasmids containing this expression cassette for preparing transgenic plant cells and plants.
