Expression of grksec.Scer\UAS in the follicle cells under the control of Scer\GAL4CY2 results in a strongly dorsalised egg shell (dorsal appendages material is seen around the entire circumference of the egg) in 85% of cases. The resulting embryos are also strongly dorsalised. Expression of grkScer\UAS.cGa under the control of Scer\GAL4Bx-MS1096 results in a strong wing vein phenotype.
