<i>trio</i> mutations affect dendritic branching of dorsal cluster Class IV ddaC neuron.

<p><b>a–b</b>) A ddaC neuron from a wandering third instar larvae of (<b>a</b>) Gal4^4–77-UAS-GFP/<i>ppk</i>-Gal4 control, and (<b>b</b>) Gal4^4–77-UAS-GFP/<i>ppk</i>Gal4; <i>trio</i>¹/<i>trio</i>^M89; scale bar 50 µm. <b>c–f</b>) Quantification of different dendritic parameters in control and <i>trio</i> mutant ddaC neurons. <b>c</b>) Dendritic branching: <i>trio</i> mutations reduce dendritic branching. <b>d</b>) Dendritic arbor area: <i>trio</i> mutations do not affect dendritic arbor area, <b>e</b>) Total dendritic length: <i>trio</i> mutations reduce total dendritic length. <b>f</b>) Average dendritic length: <i>trio</i> mutations increase average dendritic length per branch. The number of samples (n value) for each genotype is indicated by the number inside the respective bar, error bars represent standard error of the mean (SEM) and asterisks indicate p value<0.05.
