Scer\GAL4GMR.PU-mediated expression of rauScer\UAS.cSa generates a rough eye.
Additional R7 cells are formed in the eye disc when rauScer\UAS.cSa is expressed using Scer\GAL4GMR.PU.
Hyper-wrapped ommatidial axon bundles in eye imaginal disc optic stalks are observed after Scer\GAL4Mz97-mediated expression of rauScer\UAS.cSa.
Scer\GAL4da.G32-mediated expression of rauScer\UAS.cSa results in rescue of the 'loss of R7 cell' phenotype in about 60% of Df(2L)rauΔ ommatidia.
