The follicle epithelium is multilayered in sktl2.3/sktlΔ5 egg chambers in which the germline is rescued by expression of sktlScer\UAS.P\T.T:Avic\GFP under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16. Dorsal appendages of the resulting egg shells are fused.
Expression of sktlScer\UAS.P\T.T:Avic\GFP under the control of Scer\GAL4CY2 results in enlargement of the dorsal appendages.
