(A) Zebrafish retinal neural circuit showing retinal neurons and synaptic layers. GCL, ganglion cell layer; IPL, inner plexiform layer; INL, inner nuclear layer; OPL, outer plexiform layer; ONL, outer nuclear layer; RGCs, retinal ganglion cells; ACs, amacrine cells; BPs, bipolar cells; HCs, horizontal cells; PRs, photoreceptors; MGs, Müller glia. (B) Morphology of wild-type and rw147 embryos at 4 dpf. Dotted lines demarcate the eye. An arrowhead indicates abnormal lower jaw. An asterisk indicates heart edema. (C) Wild-type and rw147 mutant retinas at 4 dpf. Red and yellow arrowheads indicate the IPL and OPL, respectively. (D) A missense mutation occurs in strip1 gene of rw147 mutants leading to replacement of Leu195 with arginine. (E) Wild-type retinas labeled with anti-Strip1 antibody (upper panels) and anti-Strip1 plus Strip1-blocking peptide as a negative control (lower panels). Nuclei are stained with Hoechst. Scale bar, 50 μm. Right panels show higher magnification of outlined areas. Scale bar, 10 μm. (F) Whole-mount labeling of 3-dpf wild-type and strip1rw147 mutant retinas with anti-acetylated α-tubulin antibody. Bottom panels show higher magnification of outlined areas. Scale bar, 50 μm. (G) Projection images of single RGCs at 2 dpf expressing ath5:Gal4VP16; UAS:MYFP in wild-type and strip1rw147 mutants. Scale bar, 10 μm. (H) Projection images of single ACs at 3 dpf expressing ptf1a:GFP in wild-type and strip1rw147 mutants. Scale bar, 10 μm. (I) Projection images of single BPs at 3 dpf expressing nyx:Gal4VP16; UAS:MYFP in wild-type and strip1rw147 mutants. Scale bar, 10 μm.
