Fleury, Elodie / Huvet, Arnaud / Lelong, Christophe / De Lorgeril, Julien / Boulo, Viviane / Gueguen, Yannick / Bachere, Evelyne / Tanguy, Arnaud / Moraga, Dario / Fabioux, Caroline / Lindeque, Penelope / Shaw, Jenny / Reinhardt, Richard / Prunet, Patrick / Davey, Grace / Lapegue, Sylvie / Sauvage, Christopher / Corporeau, Charlotte / Moal, Jeanne / Gavory, Frederick / Wincker, Patrick / Moreews, Francois / Klopp, Christophe / Mathieu, Michel / Boudry, Pierre / Favrel, Pascal - 2009Background: Although bivalves are among the most-studied marine organisms because of their ecological role and economic importance, very little information is available on the genome sequences of oyster species. This report documents three large-scale cDNA sequencing projects for the Pacific oyster...Contributeur (s):

Fabioux, Caroline / Corporeau, Charlotte / Quillien, Virgile / Favrel, Pascal / Huvet, Arnaud - 2009This study investigated the potential of RNA interference, which is technically challenging in bivalve mollusc species, to assess gene function in the oyster Crassostrea gigas. We designed dsRNA targeting the oyster vasa-like gene (Oyvlg), specifically expressed in oyster germ cells. In vivo...Contributeur (s):

Le Quere, Herve / Herpin, Amaury / Huvet, Arnaud / Lelong, Christophe / Favrel, Pascal - 2009Members of the Transforming Growth factor beta (TGF-beta) superfamily of cell signalling polypeptides are known to play important roles in cell proliferation and differentiation during development and in various physiological processes of most animal clades. Recent findings in the mollusc...Contributeur (s):

Huvet, Arnaud / Jeffroy, F / Fabioux, C / Daniel, Jean-yves / Quillien, Virgile / Van Wormhoudt, A / Moal, Jeanne / Samain, Jean-francois / Boudry, Pierre / Pouvreau, Stephane - 2008To examine further a previously reported association between amylase gene polymorphism and growth in the Pacific oyster Crassostrea gigas, ecophysiological parameters and biochemical and molecular expression levels of alpha-amylase were studied in Pacific oysters of different amylase genotypes....Contributeur (s):

Huvet, Arnaud / Lapegue, Sylvie - 2008The oyster Crassostrea gigas has global distribution and for the past several years the highest annual production of any freshwater or marine organism. Economic importance of oysters motivates a great deal of biological research, which provides the most immediate scientific rationales for...Contributeur (s):

Le Moullac, Gilles / Cheize, Marie / Gastineau, Olivier / Daniel, Jean-yves / Le Coz, Jean-rene / Huvet, Arnaud / Moal, Jeanne / Pouvreau, Stephane / Van Wormhoudt, A / Samain, Jean-francois - 2008The purpose of this study is to examine the response of the oyster Crassostrea gigas to sulphide at different biological scales. A first experiment was designed to measure for 20 h the clearance (CR) and oxygen consumption (OC) rates of oysters exposed at different concentrations of sulphide (0, 3...Contributeur (s):

Fleury, Elodie / Fabioux, Caroline / Lelong, C / Favrel, P / Huvet, Arnaud - 2008Through differential screening between oyster families selected for high and low summer survival, we have characterized a new transforming growth factor-beta (TGF-beta) superfamily member. This novel factor, named oyster-gonadal-TGF beta-like (og-TGF beta-like), is synthesized as a 307 amino acid...Contributeur (s):

Gonzalez, Marcelo / Romestand, Bernard / Fievet, Julie / Huvet, Arnaud / Lebart, M / Gueguen, Yannick / Bachere, Evelyne - 2005We have characterized in the oyster Crassostrea gigas an extracellular superoxide dismutase (Cg-EcSOD) which appears to bind lipopolysaccharides (LPS). The protein has been purified from the oyster plasma and identified as a Cu/ZnSOD according to its N-terminal sequencing and biological activity....Contributeur (s):

Boudry, Pierre / Launey, Sophie / Huvet, Arnaud - 1998The two common oyster species cultivated in Europe are the flat oyster Ostrea edulis and the cupped oyster Crassostrea gigas. These species have two really different reproduction strategies (oviparity versus larviparity) and histories (natural distribution versus introductions linked to oyster...Contributeur (s):

Boudry, Pierre / Huvet, Arnaud / Fabioux, Caroline / Lapegue, Sylvie - 2001Crassostrea angulata and Crassostrea gigas, two cupped oyster taxa of Asian origin (O'Foighil et al, 1998), were successively introduced into Europe during the XVIth and the XXth century respectively (Héral and Grizel, 1991). To date, populations presumed to be C. angulata remain only in the...Contributeur (s):

Degremont, Lionel / Boudry, Pierre / Bedier, Edouard / Ropert, Michel / Soletchnik, Patrick / Huvet, Arnaud / Moal, Jeanne / Samain, Jean-francois - 2003In the scope of the Morest program, 3 series of bi-parental families of cupped oyster consisting of full and half-sib have been created in 2001, and then studied on a regular basis on several sites over the summer period. In October, major survival differences had been demonstrated between the 3...Contributeur (s):

Huvet, Arnaud / Degremont, Lionel / Labreuche, Yannick / Daniel, Jean-yves / Dubrunfaut, Thomas / Boudry, Pierre / Haure, Joel / Bedier, Edouard / Ropert, Michel / Herpin, Amaury / Cunningham, Charles / Moal, Jeanne / Samain, Jean-francois - 2005Summer mortality associated with juveniles of the oyster Crassostrea gigas is the result of a complex interaction between the host, pathogens and environment. Divergent selection based on summer survival have been applied to produce families with resistant and susceptible progeny. Here, we describe...Contributeur (s):

Boudry, Pierre / Huvet, Arnaud - 1999The taxonomic status of Crassostrea angulata and Crassostrea gigas has long been a matter of controversy. Morphological and physiological similarities, as well as homogeneity in allelic frequencies on allozymes between the populations of the two taxa, lead most authors to suggest to regroup of the...Contributeur (s):

Batista, Frederico / Leitao, Alexandra / Huvet, Arnaud / Lapegue, Sylvie / Heurtebise, Serge / Boudry, Pierre - 2005The taxonomic status of the Portuguese oyster Crassostrea angulata and the Pacific oyster Crassostrea gigas has often been a matter of controversy. Based on larval shell morphology, experimental hybridisation and electrophoretic studies of enzyme polymorphism several authors have considered these...Contributeur (s):

Huvet, Arnaud / Samain, Jean-francois / Boudry, Pierre / Bedier, Edouard / Ropert, Michel / Van Wormhoudt, A. - 2005The better understanding of physiological and environmental factors that determine optimal food conversion efficiencies is of major interest for the cupped oyster Crassostrea gigas for which the strong increase of aquaculture has been correlated in France with a decrease in productivity due to...Contributeur (s):
