CNEs containing PBX-HOX motifs driving expression in hindbrain of transgenic zebrafish.
Images show expression driven during transient transgenic assays (see methods) between 2 and 3 dpf. Insets show comparison with RFP in rhombomeres 3 and 5. hoxd.10479 (A) at ~42 hpf in ventral r5r6; hoxd.10482 lateral (B) and dorsal (C) views at ~56 hpf in lateral r2, r4, r6, pectoral fin and spinal cord; bnc2.8642 (D) at ~60 hpf in hindbrain; hmx2.9713 (E) at ~60 hpf in hindbrain and spinal cord; dachd.11206 (F) at ~72hpf in hindbrain and spinal cord; foxd3.327 (G) at ~72hpf in ventral r5 and r6; foxd3.365 throughout the central nervous system, most strongly in the ventral hindbrain, and cranial ganglia. fb: forebrain; mb: midbrain; hb: hindbrain; sc: spinal cord; pf: pectoral fin; pa: pharyngeal arches/neural crest; cg: cranial ganglia; r3 r5: rhombomeres 3 and 5.
