Statement
Reference

Flies with savGMR.PT and wtsGMR.PT have a dramatically increased proportion of yellow R8 photoreceptors and a reciprocally decreased proportion of pale R8 photoreceptors; this is suppressed in clones that are also homozygous for BEAF-32AB-KO, to the extent that the proportion of yellow R8 photoreceptors is decreased compared to wild-type controls.

Co-expression of wtsGMR.PT and savGMR.PT results in a decrease in eye size.

Expression of TaoScer\UAS.P\T.T:Zzzz\FLAG under the control of Scer\GAL4GMR.PF enhances the decrease in eye size seen when wtsGMR.PT and savGMR.PT are co-expressed.

Expression of TaoD168A.Scer\UAS.P\T.T:Zzzz\FLAG under the control of Scer\GAL4GMR.PF is unable to enhance the decrease in eye size seen when wtsGMR.PT and savGMR.PT are co-expressed.

Expression of savGMR.PT and wtsGMR.PT together at 28oC induces a mild reduction in eye size and roughness. Eye clones of ft8 misexpressing savGMR.PT and wtsGMR.PT together at 28oC exhibit small eyes, indicating that the small-eye phenotype produced by misexpressing savGMR.PT and wtsGMR.PT together is epistatic to the eye size resulting from ft8.

Coexpression of savGMR.PT and wtsGMR.PT results in a rough eye phenotype.

Expression of RassfScer\UAS.cPa under the control of Scer\GAL4GMR.PF inhibits the rough eye phenotype generated by coexpression of savGMR.PT and wtsGMR.PT.

savGMR.PT; wtsGMR.PT flies have small rough eyes. This phenotype is suppressed when somatic clones of hpoMGH1 homozygous cells are generated throughout the eye discs using Scer\FLP1ey.PN with P{neoFRT}42D.

Co-expression of savGMR.PT and wtsGMR.PT posterior to the morphogenetic furrow in the imaginal eye disc induces apoptosis.

Levels of apoptosis induced by co-expression of savGMR.PT and wtsGMR.PT posterior to the morphogenetic furrow in the imaginal eye disc is not affected in Df(2L)flp170B mutant clones.

Co-expression of savGMR.PT and wtsGMR.PT posterior to the morphogenetic furrow in the imaginal eye disc induces apoptosis. Levels of apoptosis induced by co-expression of savGMR.PT and wtsGMR.PT posterior to the morphogenetic furrow in the imaginal eye disc is not affected in bsk2 mutant clones.

The rough eye phenotype due to hpoGMR.PW is enhanced by savGMR.PT.
