Detailed Description
Statement
Reference

sliE-158 homozygous embryos exhibit severe axon guidance defects in the longitudinal connective from 14h post-fertilization onwards, as compared to controls.

Medial longitudinal tracts are seen to cross the midline in 14 hour mutant embryos.

slik04807b/sliE-158 third instar larvae show defects in photoreceptor axon targeting, with gaps in the lamina and increased numbers of axons entering the medulla.

3.1% of expected mutant embryos hatch as first instar larvae. The latest observed stage of mutants is pupa. Nerve cord length is 82% of embryo length. Midline guidance failure of repellence phenotype, evidenced by midline crossing, is mild.

Embryos show a partial midline collapse of the central nervous system.

Additional Comments
Genetic Interactions
Statement
Reference

The longitudinal tracts of embryos expressing NetBScer\UAS.cHa under the control of Scer\GAL4unspecified in a sliE-158 background appear similar to those seen in strong loss-of-function sli mutant embryos. Expression of fraScer\UAS.cKa under the control of Scer\GAL4elav.PLu does not enhance the sliE-158 longitudinal tract phenotype.

Percentage of segments with midline crossovers in robo1/sliE-158 transheterozygotes is 35%.

Embryos heterozygous for both robo1 and sliE-158 show deviation of longitudinal fascicles towards the midline in 32% of segments.
