axon & ventral nerve cord, with Scer\GAL4elav.PLu
Expression of SoxNK439.Scer\UAS under the control of Scer\GAL4elav.PLu in embryos results in specific defects in the axon scaffolding in the ventral nerve cord, including fusing and widening of the anterior and posterior commissures, thickening of the longitudinal connectives, and tangles at the segmental boundaries.
Expression of SoxNK439.Scer\UAS in the eye disc, driven by Scer\GAL4ey.PB, results in a few adult escapers with a headless phenotype.
Expression of SoxNK439.Scer\UAS in the embryo, under the control of Scer\GAL4da.G32, results in defects in the central nervous system followed by lethality at the end of embryogenesis. CNS defects include the fusion or absence of commissures and the reduction or absence of longitudinal axon tracts.
