Fig. 2 Gli2a and Gli2b regulate expression of zath3. zath3 expression in the hindbrain in 30 hpf in control (A, C, E, G, I) or gli2b morphants (B, D, F, H, J). White broken lines indicate rhombomere 4 (r4). (A, C) Control; (B, D) Gli2b morphant; (E) Gli2a morphant; (F) Gli2a/Gli2b morphant; (G) yot-/- mutant; (H) yot-/- mutant/Gli2b morphant; (I) smu-/- mutant; (J) smu-/- mutant/Gli2b morphant. Black arrows indicate ventral zath3-positive clusters of the hindbrain. White arrows (A–D) indicate D–V clusters. White lines (G, H) illustrate the D-V extent of the cluster. Abbreviations: e, ear; r4, rhombomere 4.
