Expression of SmurfScer\UAS.T:Zzzz\FLAG ectopically in the germ cells, under the control of Scer\GAL4nos.UTR.T:Hsim\VP16, results in defects in primordial germ cells, with only 37% displaying wild-type spectrosomes, with the remaining germ cells showing fragmented, faint or missing spectrosomes.
Expression of lackScer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4ptc-559.1 results in pharate adults with rudimentary wings and truncated legs.
