A reaction-diffusion wave on the skin of the marine angelfish Pomacanthus

摘要: IN 1952, Turing proposed a hypothetical molecular mechanism, called the reaction–diffusion system 1, which can develop periodic patterns from an initially homogeneous state. Many theoretical models based on reaction–diffusion have been proposed to account for patterning phenomena in morphogenesis 2–4, but, as yet, there is no conclusive experimental evidence for the existence of such a system in the field of biology 5–8. The marine angelfish, Pomacanthus has stripe patterns which are not fixed in their skin. Unlike …
