Xanthophore-melanophore interactions. (A-C) Time-lapse recordings of melanophores and DsRed-labeled xanthophores during metamorphosis. (A1-3) Wild-type, (B1-3) shady and (C1-3) homozygous leotK3 mutant xanthophores retract their protrusions to give space to the newly arriving melanophores (inside white dotted circles). (D1-1′) Wild-type, (D2-2′) shady and (D3-3′) heterozygous leotK3/+ xanthophores (white and red arrows) reorganize themselves to adopt stellate shapes upon the arrival of more melanophores in the presumptive dark-stripe regions. (D4-4′) In homozygous leotK3/tK3 mutants xanthophores (green arrowhead, xanthophore above melanophore) do not adopt a stellate shape nor loose morphology. Scale bars: 100 µm.
