Expression of barhl paralogs in the atoh7-/- retina. 40 hpf zebrafish embryos hybridized with barhl2 (A-D) or barhl1.2 (E-H) RNA antisense probe. (A, E and B, F) show dorsal view of wt (A, E) and atoh7-/- mutant (B, F) retinas, anterior is to the top. barhl1.2 expression is absent in the atoh7-/- retina (F). (C, D) dorsal view and (G, H) lateral view at the level of the tectum (t) and rhombic lips (rl), showing that expression of both barhl2 (C, D) and barhl1.2 (G, H) remains unchanged in these brain areas. White arrow in G indicates barhl1.2 expression in the retina, which is missing in atoh7-/- mutants (H).
