Fig. 7 In slb/tri double mutants the slb eye phenotype is strongly enhanced. (A, D) Frontal view of a tri (A) and slb/tri (D) double mutant at 48 hpf. (B, E) The anlage of the optic stalks expressing pax2 in a tri (B) and slb/tri (E) double mutant at 15 hpf. Dorsal views, anterior to the left. (C, F) The axonal scaffold stained for acetylated tubulin appears normal in a tri (C) mutant and is still intact but strongly deformed in a slb/tri (F) double mutant at 24 hpf (the small picture in the upper right corner of F shows a dorsal view of the axonal scaffold stained for acetylated tubulin in slb/tri embryos at 24 hpf). Side views, anterior to the left.
