Pcr-rflp para identificação de ostras perlí­­feras (Pinctada imbricate) do Brasil e Venezuela

open access: yesBoletim do Instituto de Pesca, 2017
As ostras do género Pinctada são de grande importí­¢ncia econômica devido ao seu uso extensivo na alimentação humana e cultivo de pérolas. Inclui quatro espécies: Pinctada radiata (Europa), P. imbricata (Atlí­¢ntico Ocidental) e P. fucata-martensi (Pací­

Effect of protein sources in formulated diets on the growth, immune response, and intestinal microflora of pearl oyster Pinctada fucata martensii

open access: yesAquaculture Reports, 2020
Diets affect the intestinal microflora, which in turn affects the growth performance and immune response on host. To study the effect of protein sources in formulated diets on the growth, immune response, and intestinal microflora of pearl oyster ...

Exosome-derived small non-coding RNAs reveal immune response upon grafting transplantation in Pinctada fucata (Mollusca)

open access: yesOpen Biology, 2022
Exosomes, a subset of small extracellular vesicles, carry various nucleic acids, proteins, lipids, amino acids and metabolites. They function as a mode of intercellular communication and molecular transfer.

Studies on the Pinctada fucata BMP-2 Gene: Structural Similarity and Functional Conservation of Its Osteogenic Potential within the Animal Kingdom

open access: yesInternational Journal of Zoology, 2013
Bone morphogenetic protein (BMP)-2 plays an important role in morphogenesis in both vertebrates and invertebrates. BMP-2 is one of the most powerful bioactive substances known to induce the osteogenic differentiation of mesenchymal cells. We examined the

Genetic mapping and QTL analysis of growth-related traits in Pinctada fucata using restriction-site associated DNA sequencing. [PDF]

open access: yesPLoS ONE, 2014
The pearl oyster, Pinctada fucata (P. fucata), is one of the marine bivalves that is predominantly cultured for pearl production. To obtain more genetic information for breeding purposes, we constructed a high-density linkage map of P.

Deep sequencing of ESTs from nacreous and prismatic layer producing tissues and a screen for novel shell formation-related genes in the pearl oyster. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: Despite its economic importance, we have a limited understanding of the molecular mechanisms underlying shell formation in pearl oysters, wherein the calcium carbonate crystals, nacre and prism, are formed in a highly controlled manner.

Insights from tyrosinase into the impacts of modified morphology of calcium carbonate on the nacre formation of pearl oysters

open access: yesFrontiers in Marine Science, 2022
Tyrosinase is a type-3 copper protein with six conserved histidine residues within the copper-binding sites. It participates in mollusk nacre formation.

Chromosome complement of the Indian pearl oyster Pinctada fucata (Gould) [PDF]

open access: yes, 1987
The chromosome number (n = 14, 2n = 28) of the Indian pearl oyster Pinctada fucata (Gould) is reported for the first time. It conforms with *he chromosome number reported for P. fucata martensii from Japan and P. imhricata from the Atlantic.

DNA Methylation Analyses Unveil a Regulatory Landscape in the Formation of Nacre Color in Pearl Oyster Pinctada fucata martensii

open access: yesFrontiers in Genetics, 2022
Pearl color is regulated by genetics, biological pigments, and organic matrices and an important factor that influences the pearl economic value. The epigenetic regulation mechanism underlying pearl pigmentation remains poorly understood.
