When Su(H)ΔH.Scer\UAS is driven by Scer\GAL4ptc-559.1, the loss of the anterior cross vein and nicks of the distal wing margin are occasionally seen.
Scer\GAL4ptc-559.1, Su(H)ΔH.UAS has wing | distal phenotype, enhanceable by N55e11
Scer\GAL4dpp.blk1, Su(H)ΔH.UAS has wing | distal phenotype, enhanceable by N55e11
The addition of N55e11 to Su(H)ΔH.Scer\UAS, Scer\GAL4dpp.blk1 or Su(H)ΔH.Scer\UAS, Scer\GAL4ptc-559.1 flies leads to a strong enhancement of the wing nicking phenotype.
