wing | heat sensitive (with apmd544)
apmd544/apts78j flies grown at 25oC have wings that lack most of the wing margin but have good proximo-distal growth. The addition of apHA-B.Scer\UAS severely reduces proximo-distal growth and wing size.
apmd544/apts78j flies have defective wing margins and unfused wing surfaces at 18oC. Introduction of apΔHD.Scer\UAS into this background (expressed under the control of Scer\GAL4ap-md544) eliminates the wing blade altogether.
Homozygous apts78j flies were reared at the permissive temperature, 18oC, wings develop in a quasinormal way, and at the restrictive 25oC, temperature, wings fail to develop.
Temperature-sensitive mutation. Heterozygous or homozygous females show reduced levels of ornithine decarboxylase activity relative to wild-type at 29oC. Heterozygous females are vitellogenic and homozygous females are non-vitellogenic at 29oC.

Coexpression of mewScer\UAS.cWa and fngScer\UAS.cKa under the control of Scer\GAL4ap-md544 partially rescues the apts78j/apmd544 wing phenotype; the overall size and shape, apposition of the two surfaces, position of the wing margin and pattern of the wing veins are remarkably normal. However, these wings consist entirely of ventral cell types. Firstly, the rescued wing margins lack the dorsal-specific bristles types and instead have ventral bristle types on both surfaces. Secondly, the wings have many more alula bristles than normal (which in wild-type are derived only from the ventral surface). Thirdly, a mechanosensory campaniform sensillum that is normally located only on the ventral surface of vein L3 is duplicated and present on both surfaces of the rescued wing. Finally, the morphology of the wing veins indicate that they entirely of ventral identity (the veins show a ventral corrugation pattern on both surfaces of the wing).
