Expression of Poxn^Full restores normal brain morphlogy and chemosensory bristles to Poxn^ΔM22-B5 flies, except for taste organs found on the labellum. Poxn^ΔM22-B5 females carrying Poxn^Full show diminished acetic acid egg-laying preference but still maintain a robust positional aversion to 5% acetic acid. In fact, positional aversion to 5% acetic acid is enhanced compared to wild-type.

The defects in taste bristles on the labellum seen in Poxn^ΔM22-B5 flies are not rescued by Poxn^Full, but the defects in taste bristles on the leg and anterior wing margin are rescued. The leg and antenna segmentation defects seen in Poxn^ΔM22-B5 flies are rescued by Poxn^Full. The defects in the posterior lobe and penis seen in Poxn^ΔM22-B5 males are rescued by Poxn^Full and male fertility is rescued. Poxn^Full does not rescue the flying capability of Poxn^ΔM22-B5 flies. Poxn^Full rescues the courting defects (in both daylight and red light conditions) of Poxn^ΔM22-B5 males.
