Fig. 9. Abrogation of Cyp26 activity causes moderate posteriorization. Dorsal views of whole embryos at late gastrula stage (A-H) and lateral views of late blastula stage embryos (I,J). A control morpholino or mCYP1, which is complementary to cyp26 mRNA sequence, was injected at 5 ng per embryo. Embryos were stained with otx2 (A,B), hoxb1b (C,D), meis3 (E,F) and iro1 (G,H). In addition, cyp26-GFP fusion construct was injected with either morpholino, and fluorescence was examined. (I,J). (A,C,E,G,I) Control morpholino; (B,D,F,H,J) mCYP1-injected embryos.
