Sequencing revealed no changes in the sli exons.
5.1% of expected mutant embryos hatch as first instar larvae. The latest observed stage of mutants is L2. Nerve cord length is 94% of embryo length. Midline guidance failure of repellence phenotype, evidenced by midline crossing, is severe. Longitudinal connectives wander close to the midline.
sli3149 has larval ventral nerve cord phenotype, enhanceable by robo[+]/robo11
