Expression of midF41E.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4da.G32 results in 26% embryonic lethality. The dead embryos do not show denticle belt fusion, but they have a consistent and fully penetrant defect in denticle belt rows 3, 4 and 6.
Co-expression of groScer\UAS.cAa and midF41E.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL469B does not result in denticle belt fusions.
