Genotypes in all panels: W, wildtype larvae, N = 9; B, trio-mutant background, N = 8; E, seq-enhanced trio mutants, N = 9; R, class IV da trio expression in the seq-enhanced trio mutant background, N = 10. Error bars represent the standard error of the means. (A) Dendritic density (dendrite length in μm/μm2 surface). ANOVA p-value = 0.0005; E and R are not statistically different from each other, but both are statistically different from both W and B at p<0.05. (B) Dendritic branch frequency (dendritic branches/dendrite length in μm). ANOVA p-value = 0.0022; E is statistically different than W, B and R at p<0.05. (C) Iso-neuronal avoidance defects (iso-neuronal avoidance defects/dendrite length in μm). ANOVA p-value = 0.086. (D) Hetero-neuronal tiling defects (hetero-neuronal tiling defects/μm of path length of interface between dendritic fields). ANOVA p-value = 0.197.
