Abstract
The epidermal growth factor receptor (EGFR) is a pleiotropic glycoprotein which plays a role in regulating cell proliferation, migration and differentiation. However, to date little is known about its functions in crustaceans. In this study, we successfully identified SpEGFR from mud crab Scylla paramamosain. RT-PCR result showed that SpEGFR was widely distributed in all tested tissues and highly expressed in ovary. In situ hybridization revealed that SpEGFR mainly localized in oocyte perinuclear region with notably obvious signals. In vitro experiments showed that the expression of SpVgR and SpCyclin B in ovary explants from late vitellogenic stage crabs (summer) were significantly increased when treated with 1 nM human EGF (hEGF) for 1 h, while there was no obvious change towards SpEGFR. Interestingly, as for winter crab at the same vitellogenic stage, the expression of SpVgR and SpCyclin B in ovary explants did not show significant increase until treated with higher concentration of 10 nM hEGF and longer incubation time of 12 h. In addition, the hEGF-induced effect could be suppressed by pre-treated with EGFR inhibitor AG1478 and PD153035, respectively, which further indicated that EGF-EGFR pathway played a vital role in ovarian development in mud crab. In conclusion, SpEGFR might promote ovarian development by stimulating the expression of SpVgR and SpCyclin B under hEGF-induced treatment. The different physiological response to hEGF in the same vitellogenic stage crabs between summer and winter might be attributed to the changes in metabolism and physiological sensitivity.

Abstract
Background The most critical step in the pearl formation during aquaculture is issued to the proliferation and differentiation of outer epithelial cells of mantle graft into pearl sac. This pearl sac secretes various matrix proteins to produce pearls by a complex physiological process which has not been well-understood yet. Here, we aimed to unravel the genes involved in the development of pearl sac and pearl, and the sequential expression patterns of different shell matrix proteins secreted from the pearl sac during pearl formation by pearl oyster Pinctada fucata using high-throughput transcriptome profiling. Results Principal component analysis (PCA) showed clearly different gene expression profiles between earlier (before 1 week) and later stages (1 week to 3 months) of grafting. Immune-related genes were highly expressed between 0 h – 24 h (donor dependent) and 48 h – 1 w (host dependent), and in the course of wound healing process pearl sac was developed by two weeks of graft transplantation. Moreover, for the first time, we identified some stem cell marker genes including ABCG2, SOX2, MEF2A, HES1, MET, NRP1, ESR1, STAT6, PAX2, FZD1 and PROM1 that were expressed differentially during the formation of pearl sac. The expression profiling of 192 biomineralization-related genes demonstrated that most of the shell matrix proteins (SMPs) involved in prismatic layer formation were first up-regulated and then gradually down-regulated indicating their involvement in the development of pearl sac and the onset of pearl mineralization. Most of the nacreous layer forming SMPs were up-regulated at 2 weeks after the maturation of pearl sac. Nacrein, MSI7 and shematrin involved in both layer formation were highly expressed during 0 h – 24 h, down-regulated up to 1 week and then up-regulated again after accomplishment of pearl sac formation. Conclusions Using an RNA-seq approach we unraveled the expression pattern of the key genes involved in the development of pearl sac and pearl as a result of host immune response after grafting. These findings provide valuable information in understanding the molecular mechanism of pearl formation and immune response in P. fucata.

Abstract
Implantation of a spherical nucleus into a recipient oyster is a critical step in artificial pearl production. The implanted nucleus is known to trigger cellular stress responses at several levels, yet the molecular mechanism underpinning physiological adaptation of the pearl oysters to nucleus implantation is still poorly understood. In this study, we took advantage of the iTRAQ-based proteomics and LC-MS/MS approach to look into allograft induced gene regulation at the protein expression level in the pearl oyster Pinctada fucata martensii, across a period of 30 days following nucleus implantation. A wide variety of proteins, including a group of immune-related proteins such as E3 ubiquitin-ligase and heat shock proteins, exhibited differential expression in response to the surgical operation. Further comparisons between different sampling points revealed that GO terms including "translation" and "oxidation-reduction process" and KEGG pathways including "glycolysis/gluconeogenesis" and "pyruvate metabolism" were significantly enriched at several time points, indicating the important roles of these molecular events in the stress response of pearl oysters to nucleus implantation. In addition, considerable discrepancy between protein expression level and gene transcript abundancy was identified, as only a few genes showed at least 2-fold expression changes at both proteomic and transcriptomic levels. The result implies that post-transcriptional gene regulation for the key proteins may represent an important aspect of allograft-induced stress response in the pearl oysters. Taken together, the data obtained would contribute to a deeper understanding of the molecular mechanisms enabling stress adaptation of the pearl oysters in response to nucleus implantation.

Abstract
Nucleated pearls are produced by molluscs of the Pinctada genus through the biomineralisation activity of the pearl sac tissue within the recipient oyster. The pearl sac originates from graft tissue taken from the donor oyster mantle and its functioning is crucial in determining key factors that impact pearl quality surface characteristics. The specific role of related gene regulation during gem biogenesis was unknown, so we analysed the expression profiles of eight genes encoding nacreous (PIF, MSI60, PERL1) or prismatic (SHEM5, PRISM, ASP, SHEM9) shell matrix proteins or both (CALC1) in the pearl sac (N = 211) of Pinctada margaritifera during pearl biogenesis. The pearls and pearl sacs analysed were from a uniform experimental graft with sequential harvests at 3, 6 and 9 months post-grafting. Quality traits of the corresponding pearls were recorded: surface defects, surface deposits and overall quality grade. Results showed that (1) the first 3 months of culture seem crucial for pearl quality surface determination and (2) all the genes (SHEM5, PRISM, ASP, SHEM9) encoding proteins related to calcite layer formation were over-expressed in the pearl sacs that produced low pearl surface quality. Multivariate regression tree building clearly identified three genes implicated in pearl surface quality, SHEM9, ASP and PIF. SHEM9 and ASP were clearly implicated in low pearl quality, whereas PIF was implicated in high quality. Results could be used as biomarkers for genetic improvement of P. margaritifera pearl quality and constitute a novel perspective to understanding the molecular mechanism of pearl formation.

Abstract
Marine pearl production is directly influenced by the growth speed of Pinctada fucata martensii. However, the slow growth rate of this organism remains the main challenge in aquaculture production. Epidermal growth factor receptor (EGFR), an important receptor of tyrosine kinases in animals, plays versatile functions in development, growth and tissue regeneration. In this study, we described the characteristic and function of an EGFR gene identified from P. f. martensii (PmEGFR). PmEGFR possesses a typical EGFR structure and is expressed in all studied tissues, with the highest expression level in adductor muscle. PmEGFR expression level is significantly higher in the fast-growing group than that in the slow-growing one. Correlation analysis represents that shell height and shell weight show positive correlation with PmEGFR expression (p < 0.05), and total weight and tissue weight exhibit positive correlation with it (p < 0.01). This study indicates that PmEGFR is a valuable functional gene associated with growth traits.

Abstract
In the present study, the Pif gene of the freshwater pearl aquaculture mussel, Hyriopsis cumingii (HcPif) was successfully cloned and functionally characterized. The full sequence of HcPif gene consists of 3415 base pairs, which putatively encode two proteins, HcPif90 and HcPif80. A sequence analysis revealed that HcPif contained a von Willebrand factor type A domain and a chitin-binding domain, and shared many functional residues with other Pif homologues. A highly conserved sequence, FKGLDEIELML, at the C-terminus of Pif80s was identified as the key functional site. The corresponding peptide fragment markedly modified the morphology of calcite crystallites in CaCO3 crystallization assay and might play an essential role in the interactive binding between HcPif80 and CaCO3. Moreover, real-time PCR results showed that HcPif gene was dominantly expressed in the pearl secreting tissues and its expression changed in response to the different development status of the pearl sac during pearl aquaculture. The gene expression of HcPif was maximum 7 days after mantle grafting and declined to about the control level on day 30. Our in vitro and in vivo experimental data indicated that HcPif gene possessed the inherent characteristics of a nacre formation gene and its expression might faithfully reflect the pearl secretion status of the pearl mussels examined. Our findings may extend the understanding of the biomineralization mechanism of nacre formation and provide a potential biomarker for pearl farming.

Abstract
Successful allograft of mantle tissues in certain bivalve mollusks can form pearl sacs secreting nacre for pearl production. Little was known, however, about the immune consequences in response to the tissue transplantation. In the present study, interleukin (IL)-17, one of the key regulatory genes of alloimmunity, was cloned from the triangle-shell pearl mussel (HcIL-17) Hyriopsis cumingii by high-throughput sequencing of the mantle transcriptome. The sequence of HcIL-17 contains an open reading frame of 567 bp encoding a putative protein of 188 amino acid residues. Analysis of sequence characteristics, multiple sequence alignment and phylogenetic analysis indicated HcIL-17 was a novel member in the mollusk IL-17 family. Expression of the HcIL-17 gene in donor mantle tissues and in hemocytes of recipient mussel was up-regulated dramatically within 7 days in response to the mantle tissue allograft for pearl aquaculture, suggesting remarkable proinflammatory responses during pearl sac formation in triangle-shell pearl mussels. Analysis of the time-course expression of HcIL-17 gene revealed the induction of HcIL-17 was time-dependent, reflecting the different periods of alloimmune events in triangle-shell mussels. The results of this study provide essential background information for further investigation of mollusk alloimmunity.
