We have previously reported that Bmdsx, a homologue of the sex-determining gene doublesex (dsx), was sex-specifically expressed in various tissues of the silkworm. The primary transcript of Bmdsx is alternatively spliced in males and females to yield sex-specific mRNAs that encode male-specific (BmDSXM) and female-specific (BmDSXF) polypeptides. In the studies reported here, we expressed BmDSXF in males from a ubiquitous promoter and examined its regulatory activities. We show that BmDSXF… CONTINUE READING
