Loss of SNX16 suppresses the nwk mutant phenotype. (A) Schematic of snx16 loss-of-function mutants. (B) Quantitative RT-PCR of Snx16 and CG10934 transcript levels. n = 6 for each sample. (C) Quantification of the mean satellite bouton number for muscle 4 NMJs. (D) Quantification of the mean bouton number for muscle 6/7 NMJs. (E) Elevated BMP signaling in nwk NMJs is suppressed in Snx16;nwk NMJs. Error bars are means ± SEM, and the number of samples averaged in each measurement is indicated at the base of each bar. *, P < 0.05; **, P < 0.01; ***, P < 0.005. Def, deficiency. Bars, 5 µm.
