Fig. 5. schizo acts in the central nervous system (CNS) midline cells.
Frontal views of dissected CNS preparations of stage-16 embryos stained for
the presence of all CNS axons using Mab BP102. Anterior is up. (A) Wild-type
embryo: note the regular arrangement of the Fas2-positive longitudinal
fascicles. (B) The EMS-induced schizoU112 mutation leads
to a lack of commissures. (C) Following expression of schizot2 in all
midline cells of a homozygous mutant schizo embryo, the mutant
phenotype is rescued and commissures form normally.
