HISTOLOGI JARINGAN MANTEL TIRAM (SAIBO) PADA BEBERAPA JENIS BIVALVIA SEBAGAI ALTERNATIF IMPLANTASI MUTIARA

open access: yesJurnal Pendidikan Matematika dan IPA, 2019
All types of bivalves have the potential to produce pearls. Pearls can be produced naturally and cultivated. In cultured pearls, pearl sac are obtained from saibo (slices of another bivalve mantle) that which come from pallial zone. This study wants know

Embryonic Hormetic Priming Modulates Later‐Life Thermal Tolerance [PDF]

open access: yesEcology and Evolution
Understanding the mechanisms explaining thermal tolerance variation is crucial for predicting the impact of climate change on ectotherms, especially those living near their upper thermal limits.

Phenome of pearl quality traits in the mollusc transplant model Pinctada margaritifera. [PDF]

open access: yesSci Rep, 2018
AbstractThe 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 pearl sac “chimera”) and the cultured pearls themselves.

Correlative chemical and elemental nano-imaging of morphology and disorder at the nacre-prismatic region interface in Pinctada margaritifera [PDF]

open access: yesScientific Reports, 2023
Understanding biomineralization relies on imaging chemically heterogeneous organic–inorganic interfaces across a hierarchy of spatial scales. Further, organic minority phases are often responsible for emergent inorganic structures from the atomic ...

Environmentally Driven Color Variation in the Pearl Oyster Pinctada margaritifera var. cumingii (Linnaeus, 1758) Is Associated With Differential Methylation of CpGs in Pigment- and Biomineralization-Related Genes [PDF]

open access: yesFrontiers in Genetics, 2021
Today, it is common knowledge that environmental factors can change the color of many animals. Studies have shown that the molecular mechanisms underlying such modifications could involve epigenetic factors.

Relationship of the orange tissue morphotype with shell and pearl colouration in the mollusc Pinctada margaritifera. [PDF]

open access: yesSci Rep, 2019
AbstractMolluscs 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 wild-type and two rare mutations: white albino and orange mantle. Phenotypic transmission is

Temperature and food influence shell growth and mantle gene expression of shell matrix proteins in the pearl oyster Pinctada margaritifera. [PDF]

open access: yesPLoS 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.

Whole transcriptome sequencing and biomineralization gene architecture associated with cultured pearl quality traits in the pearl oyster, Pinctada margaritifera [PDF]

open access: yesBMC Genomics, 2019
Background Cultured pearls are unique gems produced by living organisms, mainly molluscs of the Pinctada genus, through the biomineralization properties of pearl sac tissue. Improvement of P.

Species Inventory and Weight Measurements of Biofoulings Attached on the Pearl Oyster, Pinctada margaritifera, from Arakan Waters, North Sulawesi [PDF]

open access: yesJurnal Ilmiah Platax, 2018
This study was conducted with the aims to identify biofoulings living on the shell of the pearl oyster, Pinctada margaritifera and to analyse the weights of the biofoulings for three months.

Comparative transcriptomics identifies genes underlying growth performance of the Pacific black-lipped pearl oyster Pinctada margaritifera [PDF]

open access: yesBMC Genomics
Background In bivalves, the rate at which organisms grow is a major functional trait underlying many aspects of their commercial production. Growth is a highly polygenic trait, which is typically regulated by many genes with small to moderate effects ...
