    Detailed Description
    Statement
    Reference

    Following upregulation of W expression at stage 9, cells in the presumptive head and thorax regions of bcdunspecified embryos undergo cell death between stages 10 and 14. This is followed by decellularization and tissue clearance of these regions at stages 14-17. bcdunspecified larvae are missing the head and thorax and show transformation of the anterior acron into a telson.

    Gnathal and thoracic structures are deleted in embryos derived from homozygous females, and the telson is duplicated anteriorly. Anterior abdominal segments are often fused. The cephalic fold is shifted anteriorly in embryos derived from heterozygous females.

    Reference

    The increased cell death that occurs in the presumptive head and thorax regions of bcdunspecified embryos can be suppressed by expression of BacA\p35Scer\UAS.P\T.cWa under the control of Scer\GAL4tub, or by mutation of W, as observed in bcdunspecified, Df(3L)H99/WrvX1 double mutants. bcdunspecified, Df(3L)H99/WrvX1 double mutant larvae have an expanded first abdominal segment that is transformed into a posterior A8 identity, but still lack the head and thorax. Therefore, the transformed abdominal segment must usually undergo cell death in bcdunspecified single mutants, due to the mis-specificity of the cells within it. In torunspecified; bcdunspecified double mutant embryos, the mis-specified tissue which becomes the transformed telson in bcdunspecified single mutants undergoes decellularization and tissue clearance.

    Enhances the exuunspecified embryonic phenotype.
