Abstract

Diverse research programs employing complementary strategies have been uncovering cellular, molecular, and genetic mechanisms essential to avian beak development and evolution. In reviewing these discoveries, I offer an interdisciplinary perspective on bird beaks that spans their derivation from jaws of dinosaurian reptiles, their anatomical and ecological diversification across major taxonomic groups, their common embryonic origins, their intrinsic patterning processes, and their structural integration. I describe how descriptive and experimental approaches, including gene expression and cell lineage analyses, tissue recombinations, surgical transplants, gain- and loss-of-function methods, geometric morphometrics, comparative genomics, and genome-wide association studies, have identified key constituent parts and putative genes regulating beak morphogenesis and evolution. I focus throughout on neural crest mesenchyme, which generates the beak skeleton and other components, and describe how these embryonic progenitor cells mediate species-specific pattern and link form and function as revealed by 20 years of research using chimeras between quail and duck embryos.

鸟喙发育和进化的细胞、分子和遗传机制。
采用互补策略的各种研究计划一直在揭示对鸟类喙的发育和进化至关重要的细胞、分子和遗传机制。在回顾这些发现的过程中,我从跨学科的角度探讨了鸟类喙的起源,包括鸟类喙从恐龙爬行动物的下颌衍生而来、鸟类喙在主要分类群中的解剖学和生态学多样性、鸟类喙的共同胚胎起源、鸟类喙的固有模式化过程以及鸟类喙的结构整合。我将介绍描述性和实验性方法,包括基因表达和细胞系分析、组织重组、外科移植、功能增益和功能缺失方法、几何形态计量学、比较基因组学和全基因组关联研究,是如何确定调控喙形态发生和进化的关键组成部分和假定基因的。我将重点放在神经嵴间充质上,它生成了喙的骨骼和其他组成部分,并描述了这些胚胎祖细胞如何介导物种特异性模式,以及利用鹌鹑和鸭胚胎嵌合体进行的 20 年研究揭示的形态和功能之间的联系。
