Project description:We have got a yellow shell variety of Pinctada fucata martensii after years of artificial breeding. To identify differentially expressed genes between yellow shell and normal black shell pearl oysters, we performed label-free proteomic analyses by LC-MS using mantle edge tissues.

Project description:In order to screen and identify biomineralization gene, microarray technique was used to reveal tissues specific expression genes in the brunet mantle edge (ME), mantle centre (MC), and both ME and MC (ME-MC) from assembled transcriptome contigs of Pinctada fucata martensii, ideal pearl oyster for the study of biomineralization. Tissues of ME, MC, hepatopancreas, foot, gill, adductor muscle, heart and intestine were sampled from two females and one male pearl oyster. Gonad was sampled from above three individuals and another two male and one female. Equal amount RNA of each individual hepatopancreas, foot, gill, adductor muscle, heart and intestine were mixed as a composite viscera sample (CV), and equal amount gonad RNA from one male and one female were combined together as a gonad sample (GS). Hybridizations were performed with twelve samples of ME, MC, CV and GS.

Hybridizations were performed with twelve samples of ME, MC, CV and GS. Gene expression in ME, MC, gonad and other tissues were measured. Gonads were sampled from 6 individuals, and other tissues were sampled from above three individuals.

Project description:Nacre, the iridescent material found in pearls and shells of molluscs, is formed through an extraordinary process of matrix-assisted biomineralization. Despite recent advances, many parts of the biomineralization process and its evolutionary origin remain a mystery. The pearl oyster Pinctada fucata martensii is a well-known master of biomineralization, but the molecular mechanisms underlie its production of remarkable shells and pearls is not fully understood. We sequenced the highly polymorphic genome of the pearl oyster and conducted multi-omic and biochemical studies to probe nacre formation. We identified a large set of novel proteins participating in matrix-framework formation, many in expanded families, including components similar to that found in vertebrate bones such as collagen-related VWA-containing proteins (VWAP), chondroitin sulfotransferases and regulatory elements.Considering that there are only collagen-based matrices in vertebrate bones and chitin-based matrices in most invertebrate skeletons, the presence of both chitin and elements of collagen-based matrices in nacre matrices suggests that elements of chitin- and collagen-based matrices are deeply rooted and might be part of an ancient biomineralizing matrix. Our results expand the current shell matrix-framework model and provide new insights into the evolution of diverse biomineralization systems.
