A photoreceptor-specific promoter drives expression of wild-type inaD.
inaDninaE.PM rescues inaDT1
Photoreceptor cells of flies expressing inaDninaE.PM in a inaDT1 background show normal quantum bumps in response to single photons.
Flies carrying inaDninaE.PM in a inaDT1 background show normal phototaxis behaviour, normal escape jump behaviour in response to a mechanical shock and normal ability to execute an escape jump in response to sudden darkness.
