钙质蛋是所有鸟类和大多数爬行动物所产。目前对蛋壳形成和矿化的认识主要基于对一个物种--家养鸡的深入研究。鸡蛋壳的大部分成分已被鉴定。在这篇文章中，我们回顾蛋壳的显微结构和超微结构，以及最近的基因组，转录组和蛋白质组学分析的结果鸡蛋壳矩阵提请注意目前的不确定性领域，如无定形碳酸钙的潜在作用和特定性质的分子启动（核）乳头锥形成和终止栅栏层钙化。比较鸟类基因组学和蛋白质组学最近才成为可能与Taeniopygia guttata（斑胸草雀）基因组的出版。很快将公布的火鸡（Meleagris gallopavo）和鸭（Anas platyrhynchos）的基因组有望取得进一步的快速进展。这些资源将使鸟类蛋壳的有机成分及其功能意义的比较研究取得快速进展。
The calcareous egg is produced by all birds and most reptiles. Current understanding of eggshell formation and mineralization is mainly based on intensive studies of one species - the domesticated chicken Gallus gallus. The majority of constituents of the chicken eggshell have been identified. In this article we review eggshell microstructure and ultrastructure, and the results of recent genomic, transcriptomic and proteomic analyses of the chicken eggshell matrix to draw attention to areas of current uncertainty such as the potential role of amorphous calcium carbonate and the specific nature of the molecules that initiate (nucleate) mammillary cone formation and terminate palisade layer calcification. Comparative avian genomics and proteomics have only recently become possible with the publication of the Taeniopygia guttata (zebra finch) genome. Further rapid progress is highly anticipated with the soon-to-be-released genomes of turkey (Meleagris gallopavo) and duck (Anas platyrhynchos). These resources will allow rapid advances in comparative studies of the organic constituents of avian eggshell and their functional implications.
