Structure of an amorphous calcium carbonate phase involved in the formation of Pinctada margaritifera shells. [PDF]
Proc Natl Acad Sci U S A, 2022 Significance The formation mechanism of calcareous biominerals is a topic of intense research. In recent years, the importance of amorphous calcium carbonate precursors in their formation has been recognized, but until now, a quantitative ...

Assessment of an alternative Pinctada margaritifera spat collector in French Polynesia [PDF]
Aquaculture Reports, 2021 Plastic waste in the oceans is a growing concern due to its size diversity, its ubiquitous nature and its impact on both marine organisms and ecosystems. While threatened by this marine plastic litter, the aquaculture industries also represent one of its

Transcriptome and proteome analysis of
BMC Genomics, 2010 Background The shell of the pearl-producing bivalve Pinctada margaritifera is composed of an organic cell-free matrix that plays a key role in the dynamic process of biologically-controlled biomineralization.

Relationship of the orange tissue morphotype with shell and pearl colouration in the mollusc Pinctada margaritifera. [PDF]
Sci Rep, 2019 Molluscs display a vast range of shell colours both between and within species. However, only a few species show colour variation in their soft tissues. In French Polynesia, the pearl oyster Pinctada margaritifera has three tissue morphotypes: the black ...

Phenome of pearl quality traits in the mollusc transplant model Pinctada margaritifera. [PDF]
Sci Rep, 2018 The bivalve Pinctada margaritifera exhibits three main transplant phenotypes derived from the donor (from which a mantle graft tissue, the saibo, is excised), the recipient (into which the saibo is implanted with a nucleus, leading to the formation of a ...

Molecular Pathways and Pigments Underlying the Colors of the Pearl Oyster Pinctada margaritifera var. cumingii (Linnaeus 1758). [PDF]
Genes (Basel), 2021 The shell color of the Mollusca has attracted naturalists and collectors for hundreds of years, while the molecular pathways regulating pigment production and the pigments themselves remain poorly described.

Pinctada margaritifera box from Viminacium [PDF]
Starinar, 2017 A Pinctada margaritifera box was unearthed at Viminacium in 1985, at the site of Pe}ine, in a grave containing cremated remains. It was made from the shell of a pearl oyster (Pinctada margaritifera), an exotic clam whose habitat is tropical seas:

The plate collector, a new option for Pinctada margaritifera spat collection in French Polynesia
Aquaculture Reports, 2022 The aquaculture industry can constitute an important source of waste in the environment. In atoll lagoons of French Polynesia, among the materials used by pearl farmers, shade-mesh collectors can release toxic substances and are responsible of ...

Temperature and food influence shell growth and mantle gene expression of shell matrix proteins in the pearl oyster Pinctada margaritifera. [PDF]
PLoS ONE, 2014 In this study, we analyzed the combined effect of microalgal concentration and temperature on the shell growth of the bivalve Pinctada margaritifera and the molecular mechanisms underlying this biomineralization process.
