jaguar loss of function mutants display reduced muscle 6/7 NMJ length. Representative NMJs on ventral longitudinal muscles 6 and 7 from third instar Drosophila larvae of the control (A) and the jar loss of function mutant, jar322/Df(3R)crb87-5 (B). All images were acquired at the same magnification using a LSM510 confocal laser microscope. Muscle 6/7 NMJ lengths for the jar loss of function genotypes studied were significantly shorter than the control (Dunn's Multiple Comparison Test, *** = p < 0.001) (C). Bars represent mean ± SEM.
