133bp of the DopEcR first coding exon ( 3L:4370598..4370730 ) has been replaced with an in-frame GAL4 coding sequence (allowing expression of the GAL4 driver under the control of endogenous DopEcR regulatory sequences) followed by a wGMR.PH marker.
EgfrKK100051/Scer\GAL4DopEcR-GAL4 is a suppressor | partially of chemical resistant | adult stage phenotype of DopEcRGAL4
