sgl overexpression prevents dGALT motor, NMJ and HRP glycosylation defects. (A) Representative NMJs imaged with anti-horseradish-peroxidase (HRP; green) and anti-Discs-large (DLG; red) for control (dGALTC2), dGALT null with driver alone (dGALTΔAP2; UH1/+), sgl overexpression (UAS-sgl/UH1-Gal4) and dGALT null with sgl overexpression (dGALT; UAS-sgl/UH1-Gal4). (B) Normalized time required for the wandering L3 to rollover for all four genotypes. (C) Quantification of synaptic bouton number and (D) inter-bouton spacing distance. (E) Sample NMJs imaged with anti-Fasciclin-II (FASII; red) and anti-HRP (green). (F) Normalized quantification of HRP intensity. Sample size: ≥seven NMJs. Error bars show s.e.m. with significance indicated: *P<0.05, **P<0.01, ***P<0.001, ****P<0.0001, not significant (P>0.05, N.S.).
