Differential growth of the pearl oyster Pinctada fucata still exists in the aquaculture production. There is no systematic study of the entire transcriptome of differential gene expression in P. fucata in the literature. In this study, high-throughput Illumina/HiSeq™ 2000 RNA-Seq was used to examine the differences of gene expression in large (L) and small(More)
The fine microstructure of nacre (mother of pearl) illustrates the beauty of nature. Proteins found in nacre were believed to be "natural hands" that control nacre formation. In the classical view of nacre formation, nucleation of the main minerals, calcium carbonate, is induced on and by the acidic proteins in nacre. However, the basic proteins were not(More)
5-HT (5-hydroxytryptamine; serotonin) has been linked to a variety of biological roles including gonad maturation and sequential spawning in bivalve molluscs. To gain a better understanding of the effects of 5-HT on developmental regulation in the pearl oyster Pinctada fucata, the isolation, cloning, and expression of the 5-HT receptor was investigated in(More)
The pearl oyster, Pinctada fucata, a marine bivalve belonging to the family Pteriidae, is the primary species cultured for marine pearls in China and Japan (Zhang 2002). To increase the yield, successful techniques for artificial breeding have been established in China (Zhang 2002). However, with increasing acreage for artificial farming, several issues(More)
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. fucata and identified quantitative trait loci (QTL) for growth-related traits. One F1 family, which included the two(More)
There is considerable interest in decreasing the power consumption of available semiconductor metal oxide gas sensors. The low-voltage and low-power consumption metal oxide gas sensors can be easily produced by combining micromachining and thin-film technologies. The concept of micro-hotplate is one of the possible solutions. Considering of the thermal(More)
Cytokine-induced suppressor of cytokine signaling (SOCS) family acts as a negative regulator of cytokine receptor signaling to control excessive cytokine effects and inhibit a variety of signal transduction pathways, particularly the Janus kinases/signal transducers and activators of transcription (JAK/STAT) pathway. In present study, SOCS-2 homolog(More)
Interferon regulatory factors (IRFs) control many facets of the innate and adaptive immune responses, regulate the development of the immune system itself and involve in reproduction and morphogenesis. In the present study, the IRF-2 homology gene, PfIRF-2 from pearl oyster Pinctada fucata was cloned and its genomic structure and promoter were analyzed.(More)
Galectin is one important member of pattern recognition proteins that plays a pivotal role in regulating innate immune response of invertebrates. In this study, we cloned the promoter sequence of a tandem-repeat galectin from the pearl oyster Pinctada fucata (P. fucata). The quantitative real-time PCR analysis revealed that galectin mRNA expression in(More)
The granulin/epithelin precursor (GEP) encodes a glycoprotein precursor which exhibits pleiotropic tissue growth factor activity with multiple functions. Here, GEP was isolated and its role in the shell biomineralization process of the pearl oyster Pinctada fucata was investigated. Three forms of GEP mRNA were isolated from the pearl oyster (designated(More)
