Lar and Ptp69D do not play redundant roles in dendrite development of C4da neurons. (A–D) DdaC dendritic fields of an animal expressing Lar-Gal4 (A), a Lar3/Lar-Gal4 transheterozygote animal (B), an animal expressing Lar-Gal4 > Ptp69D RNAi (C), and a Lar3/Lar-Gal4 transheterozygote expressing Ptp69D RNAi (D). (E–G) Quantification of total dendrite density (E), terminal dendrite density (F), and terminal dendrite number (G) in Lar-Gal4, Lar mutant animals, Ptp69D RNAi animals, and Lar mutant animals expressing Ptp69D RNAi. ns, not significant; one-way analysis of variance and Tukey’s HSD test. For all quantifications, each circle represents an individual neuron. The number of neurons for each genotype is indicated. The black bars represent the mean, and the red bars represent the SD. (Scale bars, 50 µm.)
