 This research paper provides insight into the genetic makeup of the shell of the pearl producing bivalve pinktada margaritifra. It uses high throughput sequencing techniques to analyze the shell's organic matrix and protome, providing new information about the proteins involved in biomineralization. The authors conclude that the organic matrix contains many proteins related to biomineralization, including those responsible for calcium carbonate deposition. Additionally, they find that the mantle transcripts contain proteins associated with biomineralization, further confirming the importance of these proteins in shell formation.
