<i>kpc-1</i> controls dendrite branch extension.

<p><b>A</b> Quantification of primary branch length, expressed as a ratio of A/B to normalize for animal size (as indicated in schematic) is shown for the genotypes indicated. Percentage of animals falling within a bin (of A/B ratio) is given (illustrated with the corresponding shade of grey). Statistical significance was calculated using the F test to compare variances (*, <i>P</i>≤0.05; **, <i>P</i>≤0.01; ***, <i>P</i>≤0.001; ****, <i>P</i>≤0.0001, ns: not significant (<i>P</i>>0.05). <b>B</b>–<b>E</b> Quantification of average branch length in <i>kpc-1(gk8)</i>, <i>mnr-1(dz175)</i>, <i>sax-7(nj48)</i>, and <i>dma-1(tm5159)</i> single and double mutant animals. Data are represented as mean +/− SEM. Statistical comparisons were performed using one-sided ANOVA with the Tukey correction. Statistical significance is indicated (*, <i>P</i>≤0.05; **, <i>P</i>≤0.01; ***, <i>P</i>≤0.001; ****, <i>P</i>≤0.0001, ns: not significant (<i>P</i>>0.05)). Number of animals and dendrites scored as in legend to <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004657#pgen-1004657-g004" target="_blank">Figure 4</a>.
