Orco1 homozygotes expressing OrcoW341Δ.UAS.mCherry under the control of Scer\GAL4Orco.2.642.Hsim\VP22 show adult olfactory receptor neurons with an apparently normal dendritic morphology, as compared to controls.
Scer\GAL4Orco.2.642.Hsim\VP22/OrcoW341Δ.UAS.mCherry fails to rescue Orco1
The expression of OrcoW341Δ.UAS.mCherry under the control of Scer\GAL4Orco.2.642.Hsim\VP22 does not rescue the lack of electrophysiological activity observed in the adult olfactory receptor neurons of Orco1 homozygotes.
