Abstract
An anther-specific cDNA clone of rice, RA8, was isolated from an anther cDNA library by differential screening.
RNA blot analysis indicated that the RA8 transcript is present specifically in anthers and the transcript level
increased as flowers matured, reaching the highest level in mature flowers. The RA8 clone contains an open reading
frame of 264 amino acid residues with a hydrophobic N-terminal region. The deduced amino acid sequences did
not show significant homology to any known sequences. Genomic DNA blot analysis showed that RA8 is a single-
copy gene. A genomic clone corresponding to the RA8 cDNA was isolated and its promoter region was fused to
the -glucuronidase (GUS) gene. Transgenic rice plants exhibited anther-specific expression of the GUS reporter
