摘要
cDNA sequences are disclosed which are expressed specifically in the anther of a plant. Genomic DNA sequences corresponding to the cDNA clones are obtained using the cDNA clones as hybridization probes. Recombinant, or chimeric, DNA sequences are constructed in which the promoter sequence from anther-specific genomic clones are operatively linked to a DNA sequence coding for a desired polypeptide. Transgenic plants are made in which the chimeric DNA sequences are expressed in the anther of the transgenic plant. In a preferred embodiment, the coding DNA sequence expresses a polypeptide which will disrupt formation of viable pollen, resulting in a male-sterile plant.
