Fig. 3. CNS phenotypes of Abl and nrt mutants. Mutants were
either generated by RNAi (A-C) or by zygotic genotypes (D-F). Embryos from
stage 14/15 were stained with mAb BP102, and CNSs were dissected.
Representative examples of the overall phenotype associated with each genotype
are shown. (A) Abl null, (B) nrt null, (C) Abl and
nrt null, (D) Abl1,
nrtM54/Abl4, (E) Abl1,
nrtM100/Abl4, (F)
Df(3L)st-j7, nrtM2/Abl1,
nrtM54. Percentages below each panel indicate the percent of
segments with commissure defects; n=total segments scored. Arrows in
D,E show typical examples of segments scored as having defective
commissures.
