Xanthophore behaviors during stripe formation. (A1-5) Reorganization of xanthophores in wild type upon the arrival of metamorphic iridophores and melanophores, leading to changes in density: stellate and low density in the dark stripe areas, compact and high density in the light stripe areas. (B1-5) In the absence of iridophores in shady mutants, xanthophores maintain a uniform density. (C1-5) Xanthophores in homozygous leotK3 mutants maintain a uniform density (green arrowhead) all over the body of the fish even after the arrival of iridophores and melanophores. Scale bars: 100 μm. Dotted white boxes indicate the areas shown in Fig.5.
