The odour responses of the ab1A, ab2A and ab3A olfactory receptor neurons are unaffected in animals expressing Gα49Bpept.Scer\UAS under the control of Scer\GAL4Orco.T:Hsim\VP16.
The response of the ab1C neuron to CO[[2]] is reduced over a wide range of concentrations in animals expressing Gα49Bpept.Scer\UAS under the control of Scer\GAL4Gr21a.9.323.
