Fig. 1

The ikarus (ika) mutant phenotype. (A) Wild-type larva at 3 days of development. Note the prominent pectoral fins protruding from the flanks. (B) ika mutant larva at 3 days of development. Note the complete absence of pectoral fin structures (asterisks). (C) Alcian Blue staining of the endoskeleton of a wild-type larval pectoral fin. cl, cleithrum; sco, scapulocoracoid; pc, postcoracoid process; ed, endodermal disc. (D) Alcian Blue staining of the endoskeleton of an ika mutant larval pectoral fin. Note the complete absence of the fin endoskeleton, including the scapulocoracoid, or shoulder girdle. (E) Transverse section through a wild-type embryo at the level of the pectoral fin buds at 36 hpf. (F) Transverse section through an ika mutant embryo at the level of the pectoral fin buds at 36 hpf. Note the absence of pectoral fin buds (asterisks). Scale bars: 100 µm.
