Expression of Doa69.short3'UTR.Scer\UAS under the control of Scer\GAL4Lsp2.PH results in a slight reduction in viability, with a slightly greater effect on males than females.
Expression of Doa69.short3'UTR.Scer\UAS under the control of Scer\GAL4GMR.PF results in ommatidial fusion and disorganisation. Small holes are seen in the surface of the ommatidia at high magnification.
Expression of Doa69.short3'UTR.Scer\UAS under the control of Scer\GAL4da.G32 results in lethality but with some escapers.
Expression of Doa69.short3'UTR.Scer\UAS under the control of Scer\GAL4GMR.PF results in a variable eye phenotype (ranging from wild-type with occasional roughness through to roughened eyes and fused and missing ommatidia and pigment loss), depending on the particular P{UAS-Doa.69.short3'UTR} insertion line used and the temperature.
