Cone-specific retinal function, dark-adapted responses.

ERG responses at 5 days postfertilization (dpf). Responses were probed in the different knockout (KO) lines at five increasing light intensities under dark-adapted conditions. (A1–C1) Data are shown as boxplots of the b-wave amplitude with the box depicting the interquartile range (IQR), whiskers are 1.5 × IQR, mean is shown as diamond, median as horizontal line in the box and outliers are points outside of 1.5 × IQR. Data were collected in N ≥ 3 independent experiments and from total n ≥ 18 larvae per genotype (A: rlbp1a-KO line) or n ≥ 43 larvae per genotype (B: rlbp1b-KO line) or n ≥ 29 larvae per genotype (C: double-KO line). (A2–C2) Data are shown as mean ± standard error of the mean (SEM). (A) Respones of the rlbp1a-KO line. (A2) Repeated-measures analysis of variance (ANOVA) revealed a significant effect for genotype [F(2,435) = 33.649, p < 0.001]. (B) Respones of the rlbp1b-KO line. (B2) Repeated-measures ANOVA did not reveal any significant effect of genotype on amplitude [F(2,915) = 0.185, p = 0.83]. (C) Responses of double-KO and wild types. (C2) Repeated-measures ANOVA revealed a significant effect for genotype [F(1,290) = 99.808, p < 0.001]. Statistical analysis was performed on data in (A2, C2) after square root transformation to mitigate the impact of outliers. Pairwise comparisons between wild type (WT) and mutants at each light intensity were computed and corrected for multiple testing using the Benjamini–Hochberg correction. Significance levels of pairwise comparisons depicted as asterisks: **p < 0.01, ***p < 0.001, ****p < 0.0001. See Figure 3—source data 1 for b-wave amplitudes.
