A-D) Confocal projection through the base of zpr3+ rod outer segments (red A,B) or zpr1+ R/G cone cell bodies (red C,D) in retinas from 7dpf heterozygous (A, C) and homozygous (B, D) dscamb mutant larvae. Et1(dscambt2b:Gal4) expression is green. Insets on the right side of each panel are single-color continuations of the left side. Scale bar in A: 10μm.
E-H) Sparse Et1(dscambt2b:Gal4) labeling in individual ACs (E and F) or RGCs (G and H) in 5dpf heterozygous (E and G) and homozygous (F and H) dscamb mutant retinas. Scale bars: 10μm.
