XX fruP1.LexA/frusat15 animals expressing fruMC.Scer\UAS.T:BPV-1\AU1 under the control of Scer\GAL4Poxn.14 show robust crossing of the midline by foreleg gustatory receptor neuron (GRN) axons (this midline crossing is normally only seen in control XY males, not in control XX females).
Male-typical crossing of the midline by foreleg gustatory receptor neuron (GRN) axons is restored in XY fruP1.LexA/frusat15 animals by expression of fruMC.Scer\UAS.T:BPV-1\AU1 under the control of Scer\GAL4Poxn.14.
