Fig. 4. Ectopic innervation patterns of type III axon branches caused by disruptions in KLP68D and KLP64D. (A and B) Aberrant targeting of type III axon branches (red arrowheads) is observed in Klp68D (A) and Klp64D mutants (B). Scale bar, 20 µm. (C, left) Total number of abdominal segments used in the quantification of ectopic innervations is indicated for each genotype. The segments with normal branching patterns and aberrant type III branches in muscle 13 are indicated in white and black, respectively. (C, right) The fraction of samples with ectopic type III axons is analyzed for each genotype. ^*p<0.05, Fisher's exact test between WT and the genotype indicated. ^†p<0.05, Fisher's exact test between the paired groups (UAS-dsRNA control vs. GAL4-driven expression of UAS-dsRNA).
