Abstract
Plant development can be altered by transforming a plant with a genetic construct that includes regulatory elements and DNA sequences capable of acting in a fashion to inhibit pollen formation or function, thus rendering the transformed plant male-sterile. In particular, the present invention relates to an isolated DNA molecule comprising an anther-specific promoter, designated 5126, its operable linkage to a DNA sequence encoding a gene product and transgenic plants comprising said DNA. More particularly the gene product linked to promoter 5126 disrupts the function or formation of pollen.
