Abstract: | Background Instructions to fabricate mineralized structures with distinct nanoscale architectures, such as seashells and coral and vertebrate
skeletons, are encoded in the genomes of a wide variety of animals. In mollusks, the mantle is responsible for the extracellular
production of the shell, directing the ordered biomineralization of CaCO3 and the deposition of architectural and color patterns. The evolutionary origins of the ability to synthesize calcified structures
across various metazoan taxa remain obscure, with only a small number of protein families identified from molluskan shells.
The recent sequencing of a wide range of metazoan genomes coupled with the analysis of gene expression in non-model animals
has allowed us to investigate the evolution and process of biomineralization in gastropod mollusks. |
