Figure 1. leon mutants display abnormal NMJ morphology.
(A) Immunostaining images show NMJs of w1118, leon2/19-2, leon1/19-2 and GFP-leon-GR, leon1/19-2 for HRP (red) and Dlg (green). (B–D) Bar graphs show means ± SEM (standard error of mean) of bouton numbers (B), branch lengths (C) and muscle areas (D, quantified by phalloidin staining, not shown). (E and G) Immunostaining images co-stained by HRP (red) and Dlg (green) show transgene rescue of leon1/19-2 NMJs by UAS-leon or UAS-ED-leon driven by postsynaptic 24B-GAL4 (E) or presynaptic D42-GAL4 (G). (F and H) Bar graphs show means ± SEM of bouton numbers in postsynaptic or presynaptic rescue. Scale bars, 20 μm. All data were compared to controls unless specifically indicated by brackets, with n.s. indicating no significance, * for p<0.05, and *** for p<0.001 according to Student’s t tests.
