The Drosophila dominant wing mutation Dichaete results from ectopic expression of a Sox-domain gene.

Abstract excerpt

The dominant Drosophila wing mutation Dichaete is characterised by the deletion of proximal wing structures. By analysing a number of new Dichaete alleles, phenotypic revertants and enhancer piracy lines, we show that the wing phenotype results from ectopic expression of the Sox-domain gene Dichaete. Ectopic expression of the Sox gene results in an increase in cell death in the proximal region of the wing...
