Flies expressing UnrScer\UAS.P\T.T:Avic\GFP-EGFP under the control of Scer\GAL4en.PU exhibit reduced viability compared to controls. Lethality occurs before the third instar larval stage and males are more severely affected than females. When the temperature is increased to 29[o]C females are still present but male lethality is 100%.
Expression of UnrScer\UAS.P\T.T:Avic\GFP-EGFP under the control of Scer\GAL4Act5C.PI results in lethality at the third instar larval stage for both males and females.
Expression of UnrScer\UAS.P\T.T:Avic\GFP-EGFP in the salivary gland under the control of Scer\GAL4Sgs3.PD results in loss of banding in polytene chromosomes and decondensation of the X chromosome in males compared to controls. The phenotype is more severe at 25[o]C than at 18[o]C. No abnormalities are seen in females.
