Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Boudry, Pierre; Collet, Bertrand; Kotoulas, Georgios; Magoulas, Antonio; Hervouet, Veronique; Bonhomme, Francois; Gerard, Andre.
Highly polymorphic genetic markers can be useful tools for the analysis of parental contributions. The present paper reports 3 experiments using microsatellite markers to analyse parental contributions in controlled in vitro factorial crosses of the cupped oyster Crassostrea gigas. Parentage analysis was eased by the large polymorphism observed at the 3 loci studied. In a cross between 20 males and 20 females, a quarter of the progeny could be assigned to a given parent using a single microsatellite locus showing 28 alleles. In 3 crosses between 5 males and females, all the progeny could be assigned to a family by using 3 loci. In all cases, the combined genotyping at 2 loci allowed parentage to be detennined unambiguously. Despite the balanced gametic...

Evolutionary Patterns in Pearl Oysters of the Genus Pinctada (Bivalvia: Pteriidae)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Cunha, Regina L.; Blanc, Francoise; Bonhomme, Francois; Arnaud-haond, Sophie.
Pearl oysters belonging to the genus Pinctada (Bivalvia: Pteriidae) are widely distributed between the Indo-Pacific and western Atlantic. The existence of both widely distributed and more restricted species makes this group a suitable model to study diversification patterns and prevailing modes of speciation. Phylogenies of eight out of the 11 currently recognised Pinctada species using mitochondrial (cox1) and nuclear (18S rRNA) data yielded two monophyletic groups that correspond to shell size and presence/absence of hinge teeth. Character trace of these morphological characters onto the molecular phylogeny revealed a strong correlation. Pinctada margaritifera appears polyphyletic with specimens from Mauritius grouping in a different clade from others of...

Impact of aquaculture on the genetic structure of Mediterranean populations of Dicentrarchus
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bahri Sfar, Lilia; Lemaire, Christophe; Chatain, Beatrice; Divanach, Pascal; Ben Hassine, Oum Kalthoum; Bonhomme, Francois.
A phylogeographic analysis based on 6 polymorphic microsatellites was performed on 15 sea bass samples. five from Western Mediterranean, seven from Eastern Mediterranean and three coming from French aquaculture stocks. Among the eastern samples, three did not cluster according to their geographic origin but rather with the occidental group. Furthermore. a somewhat lower allelic diversity was observed within these particular samples, indicating that they originated from a limited number of progenitors of foreign origin. Among the aquaculture stocks, only one revealed a significant reduction of genetic variability, indicating that these stocks are largely outbred and open to wild fishes. The fact that the use of occidental fingerlings to seed broodstocks in...

Genetic structure of the common sole (Solea solea) in the Bay of Biscay: Nurseries as units of selection?
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Guinand, B; Rolland, Jean-luc; Bonhomme, Francois.
Coastal and estuarine areas in the Bay of Biscay are essential nursery habitats for sole (Solea solea). Using three intronic markers, we investigated patterns of genetic differentiation among cohorts of juveniles (0+, 1+, sub-adults) inhabiting four major nurseries in the Vilaine and Loire river estuaries, the Pertuis d' Antioche strait, and the Gironde estuary. Genetic differentiation was not significant for the age 0- and 1-groups, but was among sub-adult samples (theta(WC) = 0.017; P = 0.031). Hierarchical analyses of genotypic frequencies by nested multivariate ANOVA using redundancy analysis indicated that northern nurseries of Loire and Vilaine rivers had different patterns of genotypic variation with age than southern nurseries of the Pertuis d'...

Speciation in the Deep Sea: Multi-Locus Analysis of Divergence and Gene Flow between Two Hybridizing Species of Hydrothermal Vent Mussels
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Faure, Baptiste; Jollivet, Didier; Tanguy, Arnaud; Bonhomme, Francois; Bierne, Nicolas.
Background: Reconstructing the history of divergence and gene flow between closely-related organisms has long been a difficult task of evolutionary genetics. Recently, new approaches based on the coalescence theory have been developed to test the existence of gene flow during the process of divergence. The deep sea is a motivating place to apply these new approaches. Differentiation by adaptation can be driven by the heterogeneity of the hydrothermal environment while populations should not have been strongly perturbed by climatic oscillations, the main cause of geographic isolation at the surface. Methodology/Principal Finding: Samples of DNA sequences were obtained for seven nuclear loci and a mitochondrial locus in order to conduct a multi-locus...

Diversité génétique et dynamique du recrutement chez l'huître plate Ostrea edulis L. (2003)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lapegue, Sylvie; Taris, Nicolas; Boudry, Pierre; Langlade, Aime; Bonhomme, Francois.
Le milieu marin est un milieu difficile à appréhender car composé d'un ensemble d'organismes et d'écosystèmes caractérisés par des conditions de fonctionnement tout à fait originales et souvent difficiles d'accès. Ces spécificités peuvent être attribuées à la structure spatiale du milieu marin, qui à bien des égards, diffère du milieu terrestre. En effet si les notions de barrières géographiques sont une réalité concrète pour les organismes terrestres, elles restent rarement identifiées en milieu marin (PALUMBI 1994). Dans un tel environnement, les organismes présentent des cycles de vie souvent mal connus, notamment ceux qui associent phase benthique et phase planctonique. L'étude de la structure génétique des populations, dans un espace aussi ouvert aux...

Thermal regime and host clade, rather than geography, drive Symbiodinium and bacterial assemblages in the scleractinian coral Pocillopora damicornis sensu lato
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Brener-raffalli, Kelly; Clerissi, Camille; Vidal-dupiol, Jeremie; Adjeroud, Mehdi; Bonhomme, Francois; Pratlong, Marine; Aurelle, Didier; Mitta, Guillaume; Toulza, Eve.
Background: Although the term holobiont has been popularized in corals with the advent of the hologenome theory of evolution, the underlying concepts are still a matter of debate. Indeed, the relative contribution of host and environment and especially thermal regime in shaping the microbial communities should be examined carefully to evaluate the potential role of symbionts for holobiont adaptation in the context of global changes. We used the sessile, long-lived, symbiotic and environmentally sensitive reef-building coral Pocillopora damicornis to address these issues. Results: We sampled Pocillopora damicornis colonies corresponding to two different mitochondrial lineages in different geographic areas displaying different thermal regimes: Djibouti,...

Fitness landscapes support the dominance theory of post-zygotic isolation in the mussels Mytilus edulis and M. galloprovincialis
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bierne, Nicolas; Bonhomme, Francois; Boudry, Pierre; Szulkin, M; David, Pierre.
We studied the genetic basis of post-zygotic isolation in the marine mussels Mytilus edulis and Mytilus galloprovincialis. Evidence was obtained for a high number of recessive Dobzhansky-Muller substitutions in the genome of these two mussel taxa. We analysed the segregation of unlinked diagnostic markers in the progeny of two backcrosses and an F-2 cross, 36 h and 200 days after fertilization. Directional selection favouring M. galloprovincialis genotypes was observed in both kinds of cross. In the F-2, epistatic interactions between each pair of chromosome fragments mapped by the markers were identified in addition. Our results imply that homozygous-homozygous interactions are required for breakdown of coadaptation, in accordance with the dominance...

Using neutral, selected, and hitchhiker loci to assess connectivity of marine populations in the genomic era
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gagnaire, Pierre-alexandre; Broquet, Thomas; Aurelle, Didier; Viard, Frederique; Souissi, Ahmed; Bonhomme, Francois; Arnaud-haond, Sophie; Bierne, Nicolas.
Estimating the rate of exchange of individuals among populations is a central concern to evolutionary ecology and its applications to conservation and management. For instance, the efficiency of protected areas in sustaining locally endangered populations and ecosystems depends on reserve network connectivity. The population genetics theory offers a powerful framework for estimating dispersal distances and migration rates from molecular data. In the marine realm, however, decades of molecular studies have met limited success in inferring genetic connectivity, due to the frequent lack of spatial genetic structure in species exhibiting high fecundity and dispersal capabilities. This is especially true within biogeographic regions bounded by well-known...

Assessment of sea bass (Dicentrarchus labrax, L.) stock delimitation in the Bay of Biscay and the English Channel based on mark-recapture and genetic data
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Fritsch, Manon; Morizur, Yvon; Lambert, E; Bonhomme, Francois; Guinand, B.
Sea bass (Dicentrarchus labrax) fisheries are becoming increasingly abundant along eastern Atlantic coastlines, especially in the ICES sub-areas IV, VII and VIII, but they are still not being managed by the European Union TAC (Total Allowed Catches) system. Scientific information about these sea bass stocks is limited, but the fishery is currently managed or modelled based upon these data, separated into the ICES divisions. Clearly, failure to manage satisfactorily the fishery may lead to a decline in stocks. We therefore investigated the structure of Atlantic sea bass populations at eight microsatellite loci in the Bay of Biscay and the English Channel and, additionally, at five selected loci in Ireland and Scotland. Genetic data showed no significant...

Small effective number of parents (N-b) inferred for a naturally spawned cohort of juvenile European flat oysters Ostrea edulis
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hedgecock, Denis; Launey, Sophie; Pudovkin, A. I.; Naciri, Yamama; Lapegue, Sylvie; Bonhomme, Francois.
The great fecundity and very high larval mortality of most marine invertebrates and fish make possible substantial variance in the number of offspring contributed by adults to subsequent generations. The reproductive success of such organisms may thus resemble a sweepstakes lottery, in which a minority of progenitors succeeds in replacing an entire population, while the majority fails to procreate. One specific prediction of this hypothesis, that genetic diversity of newly settled cohorts should be less than that of the adult population, is tested in the present study. Microsatellite DNA markers were examined in naturally spawned juvenile European flat oysters Ostrea edulis (L.), collected over a 12-day period in 1993 from the western Mediterranean Sea,...

Genetic structure at different spatial scales in the pearl oyster (Pinctada margaritifera cumingii) in French Polynesian lagoons: beware of sampling strategy and genetic patchiness
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Arnaud, Sophie; Vonau, Vincent; Rouxel, Catherine; Bonhomme, Francois; Prou, Jean; Goyard, Emmanuel; Boudry, Pierre.
In order to study further the genetic structure of the pearl oyster Pinctada margaritifera in French Polynesia with a special consideration for the sampling scale, we analyzed or re-analyzed sets of data based on nuclear DNA markers obtained at different spatial scales. At a large scale (several 1,000 km), the remote Marquesas Islands were confirmed to be significantly differentiated from Tuamotu-Gambier and Society archipelagos, with a marked difference however for the two main islands that are different from each other. At a medium scale (several 10 to several 100 km), overall homogeneity was observed within and between these two archipelagos, with some exceptions. This could be attributed both to large-scale larval dispersal and to human-driven spat...

Variance of reproductive success in the European flat oyster Ostrea edulis assessed by microsatellite-based parentage analyses in a natural population and in hatchery
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lallias, Delphine; Taris, Nicolas; Boudry, Pierre; Bonhomme, Francois; Lapegue, Sylvie.
he European flat oyster (Ostrea edulis L.) is a marine bivalve whose natural geographical distribution ranges along the European Atlantic coast from Norway to Morocco, in addition to the Mediterranean and Black Sea. Previous studies of allozymes, microsat-ellites and mitochondrial differentiation over the whole range concluded that a significant divergence existed between Mediterranean and Atlantic populations, together with an isolation-by-distance pattern. However, the average mitochondrial haplotypic diversity displayed a high among populations variance, reflecting smaller effective population size in some locations. Additionally, a ten-fold quantitative difference was observed in the same study in Fst between the mitochondrial and the nuclear genomes,...

The origin and remolding of genomic islands of differentiation in the European sea bass
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Duranton, Maud; Allal, Francois; Fraisse, Christelle; Bierne, Nicolas; Bonhomme, Francois; Gagnaire, Pierre-alexandre.
Speciation is a complex process that leads to the progressive establishment of reproductive isolation barriers between diverging populations. Genome-wide comparisons between closely related species have revealed the existence of heterogeneous divergence patterns, dominated by genomic islands of increased divergence supposed to contain reproductive isolation loci. However, this divergence landscape only provides a static picture of the dynamic process of speciation, during which confounding mechanisms unrelated to speciation can interfere. Here we use haplotype-resolved whole-genome sequences to identify the mechanisms responsible for the formation of genomic islands between Atlantic and Mediterranean sea bass lineages. Local ancestry patterns show that...

Gestion des ressources génétiques de l'huître perlière Pinctada margaritifera de Polynésie française : caractérisation génétique des populations et optimisation du recrutement pour l'exploitation perlière
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Arnaud, Sophie; Goyard, Emmanuel; Prou, Jean; Vonau, Vincent; Bonhomme, Francois; Boudry, Pierre.
Exploitation of the pearl oyster Pinetada margaritifera, which has developed in French Polynesia over the last twenty years, is based mainly on the collection of natural spat. Recruitment is highly variable in space and time and so spat is very often transferred by the farmers between atolls or even between archipelagos. In previous studies, anonymous nuclear markers demonstrated that This development has coincided with a genetic homogenisation of the wild stocks since the 1980s. This suggests a high level of reproductive success on farms, which is likely to be due to the high density of animaIs when compared to the density in the wild. We used the same markers to show that the level of genetic variability observed on farms is not significantly different...

Nowadays, PCR-based DNA markers allow the study of diversity and differentiation of marine organisms at different stages of their life cycle. Our study of European flat oyster (Ostrea edulis) populations has aimed to describe their spatial and temporal dynamics. First, we analyzed adults sampled over the natural range of the species.  An Atlantic/Mediterranean differentiation pattern was observed. Results were congruent between allozymes, microsatellites and mitochondrial DNA and  support an isolation by distance model. High variability was observed in the breadth of diversity between populations using a mitochondrial marker, this highlights the small effective population sizes in some locations. A 10-fold quantitative difference was observed in Fst...

Autores: Boudry, Pierre; Collet, Bertrand; Cornette, Florence; Hervouet, Veronique; Kotoulas, G.; Bonhomme, Francois.
Oysters, like many other marine species, are characterized by very high fertilities. Natural or hatchery populations, often present very low Ne/N ratios (Hedgecock, 1994). It can be explained by very high variances of their breeding success (Li and Hedgecock, 1998), the effective population size being estimated through the temporal variance of the allelic frequencies in natural populations (Hedgecock et al., 1992) or, more directly, through the estimated number of founders in hatchery populations (Launey, 1998).

The contribution of ancient admixture to reproductive isolation between European sea bass lineages
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Duranton, Maud; Allal, Francois; Valiere, Sophie; Bouchez, Olivier; Bonhomme, Francois; Gagnaire, Pierre-alexandre.
Understanding how new species arise through the progressive establishment of reproductive isolation (RI) barriers between diverging populations is a major goal in Evolutionary Biology. An important result of speciation genomics studies is that genomic regions involved in RI frequently harbor anciently diverged haplotypes that predate the reconstructed history of species divergence. The possible origins of these old alleles remain much debated, as they relate to contrasting mechanisms of speciation that are not yet fully understood. In the European sea bass (Dicentrarchus labrax), the genomic regions involved in RI between Atlantic and Mediterranean lineages are enriched for anciently diverged alleles of unknown origin. Here, we used haplotype-resolved...

Autores: Lapegue, Sylvie; Boudry, Pierre; Mira, Sara; Taris, Nicolas; Bonhomme, Francois.
In order to understand better some fundamental aspects of the bivalve biology, one has to pay attention to the variance of their breeding success, the time structure of the populations and their effective size. An abundant literature shows the existence of a heterozygote deficit as well as positive relationships between heterozygoty and fitness components. This last point is the subject of explanatory hypotheses which have never been clearly decided between until now. One of these hypotheses is the possible existence of a certain degree of inbreeding among those populations. This is only possible in the case of separated colonies coming from a small amount of spawners, thus creating blood relations between individuals recruited from the same area, and...

A transcriptomic approach of salinity response in the euryhaline teleost, Dicentrarchus labrax
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Boutet, Isabelle; Ky, Chin Long; Bonhomme, Francois.
Euryhaline teleosts possess the capacity to osmoregulate under various environmental conditions (freshwater to hypersaline water). This physiological capacity is generally monitored using enzyme activity assays (Na+/K+-ATPase...), hormones quantification (prolactine, growth hormone) or their mRNAs expression. To date, few studies addressed the genetic correlates of adaptation to varying salinity at a molecular level in such fish. In the sea bass Dicentrarchus labrax, genetic differentiation was observed at specific allozyme loci between lagoon- and open-sea populations. In the present study, we investigated transcriptomic response of D. labrax to salt- and freshwater acclimation in two organs involved in osmoregulation, gill and intestine. By using...

The European flat oyster (Ostrea edulis L.) is a marine bivalve whose natural geographical distribution ranges along the European Atlantic coast from Norway to Morocco, in addition to the Mediterranean and Black Sea. The latest results obtained on the genetic differentiation between these populations have led us to pursue studies at a finer scale, in order to estimate the effective number of breeders and the temporal dynamics of reproduction and, more specially, recruitment. Several experiments were performed to document (1) the variance in allele frequencies during a natural settlement period; (2) the paternal contribution to fertilization by analyzing larvae sampled at the brooding stage within individual females; (3) the variance of individual...

Genetic diversity, clonality and connectivity in the scleractinian coral Pocillopora damicornis: a multi-scale analysis in an insular, fragmented reef system
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Adjeroud, Mehdi; Guerecheau, Aurelie; Vidal-dupiol, Jeremie; Flot, Jean-francois; Arnaud-haond, Sophie; Bonhomme, Francois.
Clonality and genetic structure of the coral Pocillopora damicornis sensu lato were assessed using five microsatellites in 12 populations from four islands of the Society Archipelago (French Polynesia) sampled in June 2008. The 427 analysed specimens fell into 132 multilocus genotypes (MLGs), suggesting that asexual reproduction plays an important role in the maintenance of these populations. A haploweb analysis of ITS2 sequences of each MLG was consistent with all of them being conspecific. Genetic differentiation was detected both between and within islands, but when a single sample per MLG was included in the analyses, the populations turned out to be nearly panmictic. These observations provide further evidence of the marked variability in reproductive...

Local mutagenic impact of insertions of LTR retrotransposons on the mouse genome
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Desmarais, Erick; Belkhir, Khalid; Garza, John Carlos; Bonhomme, Francois.
Solitary LTR loci are the predominant form of LTR retrotransposons in most eukaryotic genomes. They originate from recombination between the two LTRs of an ancestral retrovirus and are therefore incapable of transposition. Despite this inactivity, they appear to have a substantial impact on the host genome. Here we use the murine RMER10 LTR family as an example to describe how such elements can reshape regions of the genome through multiple mutations on an evolutionary time scale. Specifically, we use phylogenetic analysis of multiple copies of RMER10 in rodent species, as well as comparisons of orthologous pairs in mouse and rat, to argue that insertions of members of this family have locally induced the emergence of tandem repeat loci as well as many...

Autores: Taris, Nicolas; Boudry, Pierre; Bonhomme, Francois; Camara, Mark D.; Lapegue, Sylvie.
Marine species with high fecundity and high early mortality may also have high variance in reproductive success among individuals due to stochastic factors, making successful reproduction a "sweepstakes." In some cases, the impact is sufficient to reduce the effective number of breeders in wild populations. We tested two predictions of the sweepstakes reproductive success hypothesis in a French Atlantic population of the European flat oyster, Ostrea edulis, by evaluating (1) whether individuals belonging to temporally discrete recruitment cohorts within a single reproductive season displayed reduced genetic variation relative to the entire adult population, and (2) whether these temporal cohorts of recruits were genetically differentiated from each other....

Population structure of the common sole (Solea solea) in the Northeastern Atlantic and the Mediterranean Sea: revisiting the divide with EPIC markers
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rolland, Jean-luc; Bonhomme, Francois; Lagardere, Francoise; Hassan, M; Guinand, Bruno.
Spatial and temporal population genetic structures of the common sole, Solea solea, were studied in Northeastern Atlantic and Mediterranean Sea populations, using three polymorphic exon-primed intron-crossing (EPIC) markers. Results demonstrated significant multilocus differentiation among Eastern Mediterranean and a group composed by Western Mediterranean and Atlantic populations (theta = 0.150, P &lt; 0.001), but also suggested unrecorded genetic differentiation of the Adriatic Sea population. No pattern of isolation-by-distance was recorded across the range covered by sampling, from the Kattegat to the Aegean Sea. Conversely to genetically structured Mediterranean populations, Atlantic populations ranging from Denmark to Portugal could be considered as...

Genetic impact of the reproduction dynamics in the European flat oyster Ostrea edulis
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lapegue, Sylvie; Taris, Nicolas; Lallias, Delphine; Bonhomme, Francois; Boudry, Pierre.
The European flat oyster (Ostrea edulis L.) is a marine bivalve whose natural geographical distribution ranges along the European Atlantic coast from Norway to Morocco, in addition to the Mediterranean and Black Sea. The latest results obtained on the genetic differentiation between these populations have led us to persue studies at a finer scale, in order to estimate the effective number of breeders and the temporal dynamics of reproduction and, more specially, recruitment. Several experiments were performed to document (1) the variance in allele frequencies during a natural settlement period, (2) the paternal contribution to fertilization by analyzing larvae sampled at the brooding stage within individual females, (3) the variance of individual...

Autores: Lemaire, Christophe; Versini, J; Bonhomme, Francois.
To investigate the origin and maintenance of the genetic discontinuity between Atlantic and Mediterranean populations of the common sea bass (Dicentrarchus labrax) we analysed the genetic variation at a fragment of mitochondrial cytochrome b sequence for 18 population samples. The result were also compared with new or previously published microsatellite data. Seven mitochondrial haplotypes and an average nucleotidic divergence of 0.02 between Atlantic and Mediterranean populations that matches a Pleistocene allopatric isolation were found. The frequency variation at the cytochrome b locus was many times greater between Atlantic and Mediterranean populations ((&amp;#952;) over cap (C) = 0.67) than at microsatellite loci ((&amp;#952;) over cap (N) = 0.02)....

Autores: Ky, Chin-long; Vergnet, Alain; Molinari, Nicolas; Fauvel, Christian; Bonhomme, Francois.
Inter- and intraspecific crossbreeding experiments were conducted to evaluate the aquaculture potential of hybrids in the genus Dicentrarchus, focusing on fertilisation and hatching success. The experimental design consisted of 24 controlled crosses in which individual and pooled fertilisations were made between wild D. labrax individuals (8 dams and 5 sires originating from West Mediterranean and Atlantic populations) and wild D. punctatus (6 sires). Three experiments were successively performed: (1) dams from the Mediterranean population, individually considered to have good egg quality, (2) dams from Mediterranean population, individually considered to have poor egg quality and (3) crossbreeding using pooled eggs from the Atlantic population. In each...

Reduced female gene flow in the European flat oyster Ostrea edulis
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Diaz Almela, F; Boudry, Pierre; Launey, Sophie; Bonhomme, Francois; Lapegue, Sylvie.
The geographical structure of 15 natural populations of the flat oyster (Ostrea edulis L.) was assessed by single-strand conformation polymorphism (SSCP) of a 313-base-pair (bp) fragment of the mitochondrial 12S-rRNA gene. Fourteen haplotypes were observed, with one being dominant in the Mediterranean samples and another one in the Atlantic populations. The geographically extreme populations sampled in Norway and the Black Sea appeared differentiated by exhibiting the dominance of a third group of haplotypes. The results were compared to available microsatellite data at five loci. The Atlantic/Mediterranean differentiation pattern was qualitatively the same with both types of markers, confirming an isolation-by-distance pattern. The average mitochondrial...

For a long time, population geneticists have had to content themselves with analysing neutral markers to infer selection processes indirectly. The recent improvement of sequencing tools now enables them to analyse the variations of a large number of genes and therefore to spot the genes, or the amino acids, which are under the direct influence of the selection (Yang &amp; Bielawski, 2000). In order to analyse the selection processes acting on the mutations and discriminate the different factors acting on their evolution (genetic selection or drift), it is essential to compare polymorphism data between genomes of the same species/population and divergence data between species/populations (Kimura, 1983). Recently, polymorphism data has become available for a...

Two oyster species are cultivated on the French coasts: the Pacific cupped oyster (Crassostrea gigas), which has been introduced from Japan in the 1970's after the disappearance of the Portuguese oyster Crassostrea angulala, and the European flat oyster (Ostrea edulis). During the second half of the 1960's, the latter suffered successively from two diseases caused by protozoan parasites: marteiliosis (also called "maladie des Abers") and bonamiosis. In France, its production dropped from 20,000 tian in the 1960's to 2,000 today. The impact of these two pathogens as well as the exploitation of the remaining stocks show the importance of the conservation of this species, the only natural European species, whose population is more and more fragmented.

Variance in the reproductive success of flat oyster Ostrea edulis L. assessed by parentage analyses in natural and experimental conditions
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lallias, Delphine; Taris, Nicolas; Boudry, Pierre; Bonhomme, Francois; Lapegue, Sylvie.
In order to document further the phenomena of variance in reproductive success in natural populations of the European flat oyster Ostrea Midis, two complementary studies based on natural and experimental populations were conducted. The first part of this work was focused on paternity analyses using a set of four microsatellite markers for larvae collected from 13 brooding females sampled in Quiberon Bay (Brittany, France). The number of individuals contributing as the male parent to each progeny assay was highly variable, ranging from 2 to more than 40. Moreover, paternal contributions showed a much skewed distribution, with some males contributing to 50-100% of the progeny assay. The second part of this work consisted of the analysis of six successive...

Mitochondrial and microsatellite genetic differentiation of the flat oyster Ostrea edulis along the european coasts, and comparison with allozyme data

Natural populations of the European flat oyster, Ostrea edulis, have been harvested since Roman times. This species is distributed along the European Atlantic coasts, from Norway to Morocco, as well as the Mediterranean Sea and Black sea coasts. Previous studies, based on allozymes, have concluded that isolation by distance is taking place in  the Mediterranean sea and the Atlantic ocean. Because of the presumed non neutrality of these markers, another approach was made to examine the genetic differentiation of this species using nuclear microsatellite and mitochondrial markers, both considered as neutral, and to compare the results to those observed with allozymes.

Utilisation des marqueurs microsatellites pour l'étude des contributions parentales chez l'huître creuse Crassostrea gigas

Autores: Boudry, Pierre; Collet, Bertrand; Kotoulas, G.; Hervouet, Veronique; Cornette, Florence; Bonhomme, Francois; Gerard, Andre.
Numerous aquacultural species show very high fertilities. As a consequence, it is possible to produce, in hatcheries, a large amount of sibs from a small amount of parents. The sibs' genetic variability is, of course, directly linked to the number of parents involved, but it may be largely lowered by imbalanced parental contributions. Polymorphic genetic markers are very handy tools in the study of these phenomena in cultivated populations (Harris et al. 1991; Herbinger et al., 1996a; Garcia de Leon et al. 1998) or in natural populations (Ferguson et al, 1995; Kellog et al., 1995; Colbourne et al., 1996; Herbinger et al., 1996b). This document is a presentation of the results of a number of experiments, realised in the scope of the European program...

Microsatellite markers as a tool to study reproductive success in the Pacific oyster, Crassostrea gigas (Thunberg), under controlled hatchery conditions

Autores: Boudry, Pierre; Collet, Bertrand; Cornette, Florence; Hervouet, Veronique; Bonhomme, Francois.
Oysters, like many marine species have a very high fecundity. Previous studies have shown that populations, from both hatcheries and the natural environment, have very low Ne/N ratios. These observations reveal high variation in reproductive success. In order to study individual reproductive success under controlled conditions, we used microsatellite markers to quantify parental contributions in in vitro crosses (5 males and 5 females) of  Crassostrea gigas,  the Pacific oyster. High polymorphism of the microsatellites (more that 50 alleles per locus) eased the parentage identifications. The results of a cross allowing gametic competition were compared with the results from a second cross where the gametes of the same parents were kept separate for each...

PCR-based DNA markers enable the study of diversity and differentiation of marine organisms at different stages of their life cycle. Our study of European fiat oyster (Ostrea edulis) populations aimed to describe their spatial and temporal dynamics. First, we analyzed adults sampled over the natural range of the species. An Atlantic/Mediterranean differentiation pattern was observed. Similar patterns of variation were found using allozymes, microsatellites and mitochondrial DNA, aIl which support an isolation by distance model. High variability was observed in the range of diversity between populations using a mitochondrial marker, a reflection of small effective population sizes in sorne locations. A 10fold quantitative difference was observed in Fst,...
