Detailed Description
Statement
Reference

Females expressing Cf2s.hs using heat shocks produce eggs with either narrowed and fused dorsal appendages or no appendages at all. Embryos produced these females mated to wild-type males show cuticle patterning defects; expanded and fused ventral denticles.

Overexpression of P{CF2-s} causes moderate ventralisation of egg chambers; egg chambers become elongated in shape, dorsal appendages fuse and shrink and the number of main body follicle cells increases.

Additional Comments
Genetic Interactions
Statement
Reference

Overexpression of Cf2s.hs in fs(1)K101 mutants can reduce the dorsalising effects, 10% of eggs display two distinct dorsal appendages. Overexpression during oogenesis similarly rescues the maternal dorsalising effect so 12% of embryos have restored ventral denticles.
