Rescue of the kuz phenotype with panneural expression of a kuz transgene. Each panel shows three segments of the CNS from a stage 17 embryo stained with mAb 1D4. (A) A wild-type embryo, showing three parallel axon tracts on either side of the CNS midline (arrows; same panel as Fig. 3C). (B) An embryo chromosomally mutant for kuz but carrying the C155-GAL4 and pUAST-kuz constructs. These constructs drive expression of kuz from the transgene in all neurons, rescuing the wild-type pattern of axon pathways in the CNS (compare Fig. 3D).
