When expression is driven by Scer\GAL432B there is no effect on wing development. When expression is driven by Scer\GAL4h-H10 there is no effect on eye development. When expression is driven at higher levels (induced by raised temperature) with Scer\GAL432B extra wing vein appears - similar to that caused by expression of Egfr2.A887T.Scer\UAS at lower levels. When expression is driven at higher levels (induced by raised temperature) with Scer\GAL4h-H10 mutant eye phenotype appears - similar to that caused by expression of Egfr2.A887T.Scer\UAS at lower levels. Most cells are converted to photoreceptor fates.
