鸟类结构色的细胞和发育基础
Cellular and Developmental Basis of Avian Structural Coloration
摘要：
鸟类鲜艳的结构色是其表型的重要组成部分。它们是由皮肤和羽毛中丰富多样的表皮光子纳米结构产生的。与色素着色不同，色素着色的分子遗传基础正在阐明，关于生物体结构着色的基础途径知之甚少。在这里，我们审查现有的数据，发展鸟类结构色。特别地，羽毛光子纳米结构被理解为通过通常在软胶体系统中看到的物理化学力在细胞内自组装。我们为未来的研究确定了有前途的途径，可以解决目前的知识差距，这也是高度相关的先进的生物启发和仿生材料的可持续工程。
英文摘要：
Vivid structural colors in birds are a conspicuous and vital part of their phenotype. They are produced by a rich diversity of integumentary photonic nanostructures in skin and feathers. Unlike pigmentary coloration, whose molecular genetic basis is being elucidated, little is known regarding the pathways underpinning organismal structural coloration. Here, we review available data on the development of avian structural colors. In particular, feather photonic nanostructures are understood to be intracellularly self-assembled by physicochemical forces typically seen in soft colloidal systems. We identify promising avenues for future research that can address current knowledge gaps, which is also highly relevant for the sustainable engineering of advanced bioinspired and biomimetic materials.
