Flies carrying grimGMR.PA have a severely roughened, small eye.
grimGMR.PA has visible phenotype, suppressible by GlcTUAS.cKa/Scer\GAL4GMR.PY
grimGMR.PA has eye phenotype, suppressible by GlcTUAS.cKa/Scer\GAL4GMR.PY
Expression of GlcT-1Scer\UAS.cKa under the control of Scer\GAL4GMR.PY partially suppresses the small eye phenotype caused by grimGMR.PA.
