The growth of the screw dislocation of nacreous layer on Pteria penguin

Science China Earth Sciences, 2011
In response to various environmental factors in offshore South China Sea, a group of microstructures of the screw dislocation are assembled in multiphase screw dislocations on the surface of the nacreous layer of Pteria penguin from the coastal waters of Hainan Island, China.

Determination of Cd-MT in Pteria penguin with indirect non-competitive ELISA

Wuhan University Journal of Natural Sciences, 2011
Cadmium-metallothionein (Cd-MT) of Pteria penguin was used to immunize domestic rabbit in order to obtain polyclonal antibody against Cd-MT. Using the anti-Cd-MT antibody, a method of indirect non-competitive enzyme-linked immunosorbent assay (non-competitive ELISA) was established to detect shellfish Cd-MT.

Isolation, characterization and molecular evolution of a novel pearl shell lectin from a marine bivalve, Pteria penguin

Molecular Diversity, 2006
A novel lectin, PPL, was isolated from the mantle of penguin wing oyster (Pteria penguin) by affinity chromatography on mucin-Sepharose 4B and cation exchange chromatography on HiTrap SP. This lectin was estimated to be a 21-kDa monomer by gel filtration, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and matrix-assisted time of ...

The Effect of Light on the Locomotion and Byssal Reattachment of Winged Pearl Oyster Pteria Penguin (Röding, 1798) Juveniles

Journal of Shellfish Research, 2018
The present study describes the effects of various wavelengths of light on locomotion and byssal reattachment activities in the pearl oyster Pteria penguin, the most widespread cultured winged oyster for the production of valuable mabe pearls. Responses of pearl oysters to light have not yet been carefully observed and documented, despite the fact that

Creb2 involved in innate immunity by activating PpMitf-mediated melanogenesis in Pteria penguin

Fish & Shellfish Immunology, 2023
cAMP response element binding protein 2 (CREB2) acts as an intracellular transcriptional factor and regulates many physiological processes, including melanogenesis and melanocyte differentiation. In our previous research, the Creb2 gene has been characterized from Pteria penguin (P. penguin), but its role and regulatory mechanism in P.

Identification of a tyrosinase gene and its functional analysis in melanin synthesis of Pteria penguin

Gene, 2018
Tyrosinase is a key rate-limiting enzyme in melanin synthesis. In this study, a new tyrosinase gene (Tyr) was identified from Pteria penguin and its effect on melanin synthesis was deliberated by RNA interference (RNAi). The cDNA of PpTyr was 1728 bp long, containing a 5'untranslated region (UTR) of 11 bp, a 3'UTR of 295 bp, and an open reading ...

Seasonal Changes in Recruitment ofPteria penguinin North Queensland, Australia

Journal of Shellfish Research, 2011
Spat recruitment of the winged pearl oyster Pteria penguin, in relation to season, substrate type, and depth was investigated at Orpheus Island in north Queensland for 27 mo, from February 2008 to April 2010. Two substrate types (70% shade cloth and open-weave polypropylene mesh bags) were deployed at 2 depths (4 m and 6 m) and checked every 6 wk for 3

Identification and function analysis of BCL2 in immune response of Pteria penguin

Fish & Shellfish Immunology
B-cell lymphoma/leukemia-2 (BCL2), an anti-apoptotic factor in the mitochondrial regulatory pathway of apoptosis, is critically important in immune defenses. In this study, a novel BCL2 gene was characterized from Pteria penguin (P. penguin). The PpBCL2 was 1482 bp long, containing an open reading frame (ORF) of 588 bp encoding 195 amino acids.
