Sdc and dally play partially redundant roles in promoting dendritic growth of C4da neurons. (A–H′) DdaC in the Gal4^hh control (A and A′) and animals expressing dally RNAi (B and B′), dlp RNAi (C and C′), Sdc RNAi (D and D′), dally dlp RNAi (E and E′), dlp Sdc RNAi (F and F′), dally Sdc RNAi (G and G′), and dally dlp Sdc RNAi (H and H′) in the hh domain. Blue dots outline hh domains (Upper). Lower panels show Gal4^hh-expressing cells in green and C4da dendrites in magenta. (I and J) Quantification of terminal dendrite density (I) and terminal dendrite number (J) in hh domains. *P ≤ 0.05; **P ≤ 0.01; ***P ≤ 0.001; ns, not significant; ANOVA and Tukey’s HSD test. For all quantifications, each circle represents a neuron. The numbers of neurons are indicated. Black bar, mean; red bars, SD. (Scale bars, 50 µm.)
