DNA fingerprinting of pearls to determine their origins. [PDF]

PLoS ONE, 2013
We report the first successful extraction of oyster DNA from a pearl and use it to identify the source oyster species for the three major pearl-producing oyster species Pinctada margaritifera, P. maxima and P. radiata. Both mitochondrial and nuclear gene

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.

Growth and survival of Pinctada martensii (Dunker) postlarvae under concurrent variation in temperature, algal ration and stocking density

Aquaculture Reports, 2021
The growth and survival of pearl oyster postlarvae (Pinctada martensii) were studied under laboratory conditions. A face-centered central composite experimental design was used with 3 factors, temperature (18―34 °C), algal ration (5―100 cells μL―1) and ...

Cloning and functional characterization of PmΔ5FAD in pearl oyster Pinctada fucata martensii

Aquaculture Reports, 2022
Pinctada fucata martensii produces high-quality pearls. However, excess immune and inflammatory response after grafting operation will lead to nucleus rejection, pearl sac formation failure, and death of the host pearl oyster. Polyunsaturated fatty acids

The pearl oyster (Pinctada margaritifera) aquaculture in French Polynesia and the indirect impact of long-distance transfers and collection-culture site combinations on pearl quality traits

Aquaculture Reports, 2019
In French Polynesia, the P. margaritifera pearl aquaculture industry is spread over a vast area, as large as Europe. All the oysters for this the highly economically important activity are supplied from just a few collection lagoons, but they are grown ...
