Insertion in the 5' untranslated region.
rdo8-156 mutants exhibit a reduced ocelli phenotype. The lateral lenses exhibit relatively normal scalloping while the medial ocellus exhibit corneal nipples.
rdo8-156 is rescued by rdoUAS.fl/Scer\GAL4rdo-8-156
The rdo8-156 mutant phenotype can be rescued through expression of rdoScer\UAS.fl under the control of Scer\GAL4rdo.
