Df(2L)dp-79b, Dp(2;2)dppd21, Or33cUAS.cDa, Scer\GAL4Or22a.8010 has olfactory neuron & antennal sense organ phenotype
Expression of Or33cScer\UAS.cDa under the control of Scer\GAL4Or22a.8010 in a "Δab3A" background (which is a synthetic deletion created using Df(2L)dp-79b and Dp(2;2)dppd21 combined on to the same chromosome, and in which Or22a and Or22b is deleted, resulting in antennal olfactory receptor neuron ab3A losing its odorant response - see FBrf0173068) confers a response to E2-hexenal and weaker responses to several other odorants. Coexpression of both Or85eScer\UAS.cGa and Or33cScer\UAS.cDa in this background results in odor-response properties that are similar, although not identical, to those resulting from expression of Or85eScer\UAS.cGa alone, when tested with a limited number of odor stimuli.
The ab3A neurons still target the DM2 glomerulus (the wild-type target for ab3A neurons) in "Δhalo" animals (in which Df(2L)dp-79b and Dp(2;2)dppd21 are recombined onto the same chromosome to create a synthetic deficiency) expressing Or33cScer\UAS.cDa under the control of Scer\GAL4Or22a.8197.
The ab3A neurons still target the DM2 glomerulus (the wild-type target for ab3A neurons) in Df(2L)dp-79b/Dp(2;2)dppd21 animals expressing Or33cScer\UAS.cDa under the control of Scer\GAL4Or22a.8197.
