The impaired male pheromone (cis-vaccenyl acetate, cVA) detection characteristic for Snmp1¹/Snmp1² adult males is partially rescued by expression of either ninaD::Snmp1^{Scer\UAS.T:Avic\GFP-EGFP} or ninaD^{Scer\UAS.T:Avic\GFP-EGFP} under the control of Scer\GAL4^Or67d.PF : the lack of Or67d neuronal activity (measured by extracellular recordings in individual sensilla) is significantly restored. In the case of ninaD^{Scer\UAS.T:Avic\GFP-EGFP} the rescue effect is weak and only observed when the cVA is delivered in close range (as opposed to in an air-stream - in that assay no rescue is observed at all).

The impaired male pheromone (cis-vaccenyl acetate, cVA) detection characteristic for Snmp1¹/Snmp1² adult males is partially rescued by expression of under the control of Scer\GAL4^Or67d.PF : the lack of Or67d neuronal activity (measured by extracellular recordings in individual sensilla) is significantly, albeit not fully, restored.

lush¹ Snmp¹/lush¹ Snmp² double mutant Or67d-expressing olfactory sensory neurons show an increase in spontaneous activity compared to control neurons, as is seen in Snmp¹/Snmp² single mutant neurons.

Snmp¹ Or83b²/Snmp² Or83b¹ double mutant Or67d-expressing olfactory sensory neurons show show severely decreased spontaneous activity compared to control neurons, as is seen in Or83b¹/Or83b² single mutant neurons.

Olfactory sensory neurons expressing Or22a^Scer\UAS.cLb under the control of Scer\GAL4^Or67d.PF still show the ectopic responses to a panel of known Or22a ligands (ethyl butyrate, methyl butyrate, pentyl acetate, methyl hexanoate and methyl octanoate) in a Snmp¹/Snmp² background, but the endogenous response of these neurons to cis-vaccenyl acetate is lost in the Snmp¹/Snmp² background.

The impaired male pheromone (cis-vaccenyl acetate, cVA) detection characteristic for Snmp1¹/Snmp1² adult males is partially rescued by expression of any of the following: Apol\Snmp1^{Scer\UAS.T:Avic\GFP-EGFP}, Amel\Snmp1^{Scer\UAS.T:Avic\GFP-EGFP}, or Mmus\Cd36^{Scer\UAS.T:Avic\GFP-EGFP} under the control of Scer\GAL4^Or67d.PF : the lack of Or67d neuronal activity (measured by extracellular recordings in individual sensilla) is significantly, albeit not fully, restored.

Adult flies expressing Hvir\HR13^Scer\UAS.cKa under the control of two copies of Scer\GAL4^Or67d-GAL4-1 cannot detect the moth Heliothis virescens sex pheromone (Z)-11-hexadecenal if they are also transheterozygous for Snmp1¹/Snmp1².

The failure of adult flies transheterozygous for Snmp1¹/Snmp1² to detect the moth Heliothis virescens sex pheromone (Z)-11-hexadecenal when they are also ectopically expressing Hvir\HR13^Scer\UAS.cKa under the control of two copies of Scer\GAL4^Or67d-GAL4-1 can be partially rescued by co-expression of Mmus\Cd36^WT.Scer\UAS : the Or67d neurons now display significant activity (measured by extracellular recordings in individual sensilla) upon (Z)-11-hexadecenal presentation.

The failure of adult flies transheterozygous for Snmp1¹/Snmp1² to detect the moth Heliothis virescens sex pheromone (Z)-11-hexadecenal when they are also ectopically expressing Hvir\HR13^Scer\UAS.cKa under the control of two copies of Scer\GAL4^Or67d-GAL4-1 can be restored by co-expression of Snmp1^WT.Scer\UAS or Snmp1^{A401Y.Scer\UAS} or Snmp1^{V353Y.Scer\UAS} or (to a lesser extent) Snmp1^{T274Y.L439Y.Scer\UAS} : The Or67d neurons display significant activity (measured by extracellular recordings in individual sensilla) upon (Z)-11-hexadecenal presentation when co-expressing any of the aforementioned Snmp1 transgenes.

The response to the H.virescens (Z)-11-hexadecenal pheromone that is seen in olfactory sensory neurons expressing Hvir\HR13^Scer\UAS.cKa under the control of Scer\GAL4^Or67d.PF in a wild-type background is almost completely abolished by the addition of Snmp¹/Snmp².
