 This research paper provides a detailed overview of the genetic makeup of the shell of the pearl-producing bivalve-pink-tardum margaritifera. It uses both transcriptomic and proteomic techniques to analyze the shell's components and identify proteins implicated in biomineralization. The authors conclude that the shell is composed of a diverse array of proteins, many of which are implicated in biomineralization.
