Exposure to epinephrine rescued axial curvature of sspo mutants. (A) sspo mutants (arrows) and siblings at 48 hpf. (B) sspo mutants and siblings at 48 hpf after epinephrine treatment. Note absence of embryos with curved bodies. Embryos shown in A and B are representative of a minimum of 100 embryos analysed in two independent experiments. Note, some embryos are devoid of body pigmentation as the sspo allele is maintained in the nacre mutant background that prevents body pigmentation in homozygotes. Scale bars: 1 mm.
