Fig. 2
Homozygous and heterozygous phenotypes of the 78N knjaz (knz) mutant. (a, b) Lateral view of live 4 dpf wt (a) and 78N knjaz (knz) mutant (b) larvae. (c?f) Lateral (c, d) and (e, f) views of Ab/AR-stained 4 dpf wt (c, e) and 78N knjaz (knz) mutant (e, f) embryos. Arrows in (d) and (f) indicate Meckel′s cartilage, and arrowheads in (d) indicate missing branchial arche cartilages. (g?j) Lateral view of AR stained of adult wt (g, i) and 78N knjaz (knz) mutant (h, j) zebrafish. Arrow in (h) points to altered upper jaw morphology in knz mutants. Arrow in (j) points to defects in pleurostyle and hypural bones of knz mutant. Abbreviations: ch, ceratohyal; eth, ethmoid plate; e, eye; M, Meckel′s cartalige; wt, wild type; 1-5, branchial arches.
