In order to understand growth features of pearl oysters in the genus Pinctada, i.e. Pinctada fucata, Pinctada margaritifera, and Pinctada sugillata in Taiwan, a total of 3062 wild individuals of these species from juvenile to adult were collected monthyly from March 2001 to April 2002 in Jukeng, Pingtung County, south-west Taiwan.

Mantle regeneration in the pearl oysters Pinctada fucata and Pinctada margaritifera
Aquaculture, 2005Abstract Mantle tissue in pearl oysters (Pteriidae) is responsible for secreting the mother-of-pearl or nacre lining the shell. When grafted into another oyster, excised mantle tissue, commonly called ‘saibo’, is responsible for cultured pearl production. This study was undertaken to assess the process of mantle regeneration in the Akoya pearl oyster

The pearl oyster Pinctada maxima exhibits great difficulty to culture pearls through nuclear insertion with an allograft, but it is easy for P. fucata to culture pearls after allografting. If P. fucata could be used as a surrogate mother to culture P. maxima pearls, it would benefit the pearl culture industry of P. maxima.

Ecological Study on Biomineralization in Pinctada fucata
2018Pinctada fucata inhabits in tropical and subtropical seas, so the sea water conditions have great impacts on its growth and shell formation. To determine the potential effects of global climate change and the water pollution on the oyster growth in the near future, we have conducted a series of studies about the metabolism and shell formation of P ...

A microstructural study of individual nacre tablet of Pinctada maxima
Journal of Structural Biology, 2013Nacre tablets from the shell of Pinctada maxima were studied with SEM, TEM and STEM. The systematic nanolath morphology on the (001) surface of nacre tablets was observed after acidic etching and mechanical polishing. The nanolaths were along the [100] crystallographic orientation of aragonite crystal.

Cellular Regulation of Biomineralization in Pinctada fucata
2018Because it is widely recognized that the mantle tissue controls nacre precipitation, intensive studies have been conducted to unravel the regulatory mechanism underlying nacre formation. In this chapter, we will focus on the cellular regulation of shell formation in the pearl oyster Pinctada fucata.

Molecular Basis of Biomineralization in Pinctada fucata
2018Biomineralization is the accumulation and formation of minerals regulated by living organisms transforming into biological structures and tissues. This is an extremely widespread phenomenon since we’ve found many creatures in all six taxonomic kingdoms which could form biominerals, and more than 60 different types of them have been identified, such as ...

Molecular Mechanism of the Nacreous Layer Formation in Pinctada maxima
Biochemical and Biophysical Research Communications, 2000We have cloned the cDNAs that encode two kinds of molluscan shell matrix proteins, namely N66 and N14, in the nacreous layer of Pinctada maxima. N66 is composed of carbonic anhydrase-like and repeat domains, as described for nacrein (1) in the pearls of P. fucata. N14 is homologous to N16, recently found in the nacreous layer of P.

Arsenic compounds accumulated in pearl oyster Pinctada fucata
Chemosphere, 2003We investigated the water-soluble arsenic compounds present in the soft tissues of both the pearl-free and the pearl-containing pearl oysters. After dividing the soft tissue into five parts, i.e., adductor muscle, foot, mantle, viscera and gill, each part was analyzed by high-performance liquid chromatography-inductively coupled plasma mass ...

Genetic structure and polymorphisms of the N16 gene in Pinctada fucata
Gene, 2012The molluscan shell is a composite of inorganic crystals comprising calcium carbonate and a minute amount of organic matrix. The organic matrix (OM) is intimately involved in every step of shell formation and has consequently received much attention in recent years. However, most of the deposited information has resulted from cDNA analysis, with little
