Morpholino knockdown of rpz suppresses the homozygous rapunzel phenotype. Heterozygous rapunzel adult zebrafish were intercrossed and the resulting embryos injected at the 1-2 cell stage with either a morpholino targeting the start site of rpz (MOrpz) (A), a morpholino targeting rpz2 (MOrpz2) (B) or a rpz 5 base pair mismatched control morpholino (MOrpz_5bm) (C). A. Injection of MOrpz suppresses the homozygous embryonic rapunzel phenotype. The rapunzel homozygous phenotype was not suppressed in embryos injected with MOrpz2 (B) or MOrpz_5bm (C). PCR, DdeI digestion and electrophoresis confirmed that the embryos in A, B, and C are all homozygous for the rapunzelc14 allele (not shown).
