Abstract
The invention can be summarized as follows. Several silk-specific genes were isolated from corn silk. The specificity of their expression was determined by Northern analysis. A regulatory region was obtained from the silk gene, C3, and found to direct silk, and pistil, expression in transient assays and transgenic plants, in both monocot and dicot plants. The regulatory region of a silk gene may be used to drive the expression of a gene of interest within pistil or silk-tissues for a range of utilities including pathogen resistance or female sterility.
