Eyespot colour pattern determination by serial induction in fish: Mechanistic convergence with butterfly eyespots
Vertebrate and invertebrate colour pattern determination mechanisms are considered distinct; recently, however, both fish and butterfly colour patterns have been partly explained by reaction-diffusion mechanisms. Here, we show that multi-coloured eyespots of the spotted mandarin fish, which are remi...

description | Vertebrate and invertebrate colour pattern determination mechanisms are considered distinct; recently, however, both fish and butterfly colour patterns have been partly explained by reaction-diffusion mechanisms. Here, we show that multi-coloured eyespots of the spotted mandarin fish, which are reminiscent of butterfly eyespots, are determined by the serial induction of colour patterns. The morphological characterisation of eyespots indicates a sequence of colour pattern development and dynamic interactions between eyespots. A substantial part of an eyespot can be surgically removed and is then reconstructed by regeneration. Strikingly, ectopic patterns are induced by damage at a background (eyespotless) area, but focal damage did not change the eyespot size. Early stages of damage repair were accompanied by calcium oscillations. These results demonstrate that fish eyespots are determined by serial induction, which is likely based on a reaction-diffusion mechanism. These findings suggest mechanistic similarities between the fish and butterfly systems. |
