To review the current state of knowledge regarding avian eggshell structure, matrix constituents, and mineralization processes, while identifying unresolved questions in shell calcification.
Synthesized structural, ultrastructural, genomic, transcriptomic, and proteomic data derived primarily from the domestic chicken (Gallus gallus).
Assessed emerging comparative avian genomic and proteomic resources, including zebra finch (Taeniopygia guttata), turkey (Meleagris gallopavo), and duck (Anas platyrhynchos).
The majority of organic matrix components and inorganic layers comprising the Gallus gallus eggshell have been cataloged.
Crucial mechanistic uncertainties remain, specifically the role of transient amorphous calcium carbonate and the specific molecular triggers that nucleate mammillary cones and terminate palisade layer calcification.
The availability of non-chicken avian genomes enables comparative analyses to determine conserved versus species-specific functional constituents of the eggshell matrix.
