Embryonic Hormetic Priming Modulates Later‐Life Thermal Tolerance [PDF]
Ecol EvolThis study investigates how early‐life thermal environments affect later thermal tolerance in the black‐lip pearl oyster, Pinctada margaritifera. Developmental thermal priming had contrasting, family‐specific effects on thermal tolerance, with conserved stress‐response pathways but evidence of priming‐induced regulatory network reorganization.

Sustainability and traceability in marine cultured pearl production [PDF]
, 2014 For centuries, wild pearl oysters and mussels were fished in the quest for natural pearls and shell material. This eventually led to the drastic overexploitation of oyster stocks in many areas of the globe.

A homeodomain transcription factor gene, PfMSX, activates expression of Pif gene in the pearl oyster Pinctada fucata. [PDF]
PLoS ONE, 2014 We reported pearl oyster Pinctada fucata cDNA and genomic characterization of a new homeobox-containing protein, PfMSX. The PfMSX gene encodes a transcription factor that was localized to the nucleus.

Histopathology of oedema in pearl oysters Pinctada maxima [PDF]
Diseases of Aquatic Organisms, 2010 In October 2006, severe mortalities (80 to 100%) were reported in pearl oyster Pinctada maxima production farms from Exmouth Gulf, Western Australia. Only P. maxima were affected; other bivalves including black pearl oysters P. margaratifera remained healthy. Initial investigations indicated that the mortality was due to an infectious process, although

Exploring HSP90 as a Biomarker for Marine Heatwaves in Pinctada maxima
Frontiers in Marine Science, 2022 Many species, particularly marine organisms, are becoming more vulnerable to marine heatwaves due to climate change. Marine species anticipate perishing during marine heatwaves, but there is a growing interest in learning why some can resist.

Anisotropy of Mechanical Properties of Pinctada margaritifera Mollusk Shell [PDF]
Nanomaterials, 2020 The mechanical properties such as compressive strength and nanohardness were investigated for Pinctada margaritifera mollusk shells. The compressive strength was evaluated through a uniaxial static compression test performed along the load directions parallel and perpendicular to the shell axis, respectively, while the hardness and Young modulus were ...
