Ultrastructure analysis of atp11anl1007 mutant photoreceptors. (A–D) Photoreceptors in ultrathin sections show a reduction of outer segments in homozygous mutants when compared to wild-type siblings. (E–H) This phenotype partially resolves when mutant larvae are raised in the dark. Quantification of outer segment number (I), length (J) and mitochondrial number (K) confirm a partial rescue via dark-rearing conditions. Data are mean±s.e.m. ***P<0001, **P<0.001, *P<0.01 (one-factor ANOVA with Tukey’s analysis for multiple comparisons). Wild type light, n=6; mutant light, n=6; wild type dark, n=3; mutant dark, n=3. Larvae are at 6 dpf. Scale bars: 2 µm in F for A,B,E,F; 1 µm in H for C,D,G,H.
