    Abstract: The invention relates to stamen-specific promoters derived from corn genes. These promoters includes two DNA sequences selected from sequences in SEQ ID NO:2 or SEQ ID NO:3. The invention also includes DNA including the stamen-specific promoters operably linked to a heterologous structural gene. The structural genes include those such as ribonuclease, barnase, and an A fragment of diphtheria toxin.
