Sex- and Diet-Specific Changes of Imprinted Gene Expression and DNA Methylation in Mouse Placenta under a High-Fat Diet Inra
Gallou-Kabani, C.; GABORY, A.; Tost, J.; Karimi, M.; Mayeur, S.; Lesage, J.; Boudadi, E.; Gross, M-S; Taurelle, J.; Vigé, A.; Breton, C.; Reusens, B.; Remacle, C.; Vieau, D.; Ekström, T. J.; Jais, J-P; Junien, C..
Changes in imprinted gene dosage in the placenta may compromise the prenatal control of nutritional resources. Indeed monoallelic behaviour and sensitivity to changes in regional epigenetic state render imprinted genes both vulnerable and adaptable. We investigated whether a high-fat diet (HFD) during pregnancy modified the expression of imprinted genes and local and global DNA methylation patterns in the placenta. Pregnant mice were fed a HFD or a control diet (CD) during the first 15 days of gestation. We compared gene expression patterns in total placenta homogenates, for male and female offspring, by the RT-qPCR analysis of 20 imprinted genes. Sexual dimorphism and sensitivity to diet were observed for nine genes from four clusters on chromosomes 6,...

Shoot-root control of nitrate tolerance of N2 fixation in spontaneously tolerant soybean lines: reciprocal grafting experiments Inra
Raffin, A.; Roumet, P..
Une caractérisation de la tolérance au nitrate de la fixation de l’azote chez le soja a été réalisée dans 2 expérimentations de greffes réciproques, avec des dispositifs de types top cross et diallèle. Le contrôle de la tolérance au nitrate par les parties aériennes et racinaires de la plante a été étudié chez une lignée tolérante (Tielingbaime), un cultivar sensible (Kingsoy), et 5 lignées issues de leur croisement. Les 2 expérimentations ont démontré l’existence d’un contrôle par la partie aérienne de la tolérance au nitrate de la nodulation. Le caractère de tolérance permet le maintien de nodosités en plus grand nombre et de masse spécifique supérieure en présence de nitrate. La régulation de la fixation de l’azote en présence de nitrate serait...

Situation nutritionnelle dans le monde : changements et enjeux IRD
Delpeuch, Francis; Maire, Bernard.
En dépit d'une situation nutritionnelle mondiale qui s'améliore lentement depuis plusieurs décennies, la scène reste dominée par la persistance massive de problèmes de sous-alimentation et de malnutrition au Sud et de maladies chroniques liées au régimes alimentaire du Nord. Depuis quelques années sont cependant apparus des changements considérables dans la perception que pouvait avoir la communauté internationale de la nature des problèmes nutritionnels, de leur relation avec la pauvreté et de leur impact sur le développement. Ces changements offrent de nouvelles perspectives d'approche dans la prévention et la lutte contre les malnutritions. Enfin, à côté des problèmes persistants, on note l'émergence récente, dans les pays à faible ou moyen revenu, des...

Stratégies pour de nouveaux progres techniques et économiques en aviculture Inra
Sauveur, B..
La réunion d’arguments scientifiques, techniques et économiques peut permettre d’élaborer encore de nombreuses stratégies de progrès pour l’aviculture. Ainsi, les améliorations à attendre de la génétique quantitative classique sont loin d’être terminées. Des critères nouveaux (anatomiques ou physiologiques) de sélection sont en préparation et ils pourront être complétés par des études de polymorphismes d’ADN utilisés comme indicateurs de caractères économiques, notamment de résistance à certaines maladies. Ces méthodes sont cependant coûteuses, de même que la transgénèse qui n’en est encore, quant à elle, qu’au stade des études méthodologiques. Elles ne seront donc mises en place que si la possibilité d’amélioration d’un critère économique important est...

The "Catfish Asia" project : backgrounds, aims and prospects IRD
Legendre, Marc.
Catfishes, and in particular #Clariidae$ and #Pangasiidae$, are important aquatic resources in Asia, where their culture represented an annual production of about 124,000 t in 1993. In the clariids, this production results mostly from the use of F1 hybrids between the introduced African catfish (#Claris gariepinus$) and various local clariid species. In the pangasiids, various culturing techniques were empirically developed for some native species, whose juveniles are most often captured in the wild. Further development of this catfish culture industry faces serious problems related to the poorly known systematic of these fish groups, the scarce knowledge of the biology and aquaculture potential of autochthonous species, the limitation of seed supply and...

Understanding the reproductive performance of a dairy cattle herd by using both analytical and systemic approaches: a case study based on a system experiment Inra
Gouttenoire, L.; Fiorelli, J.L.; Trommenschlager, J.M.; Coquil, X.; Cournut, S..
Reproductive performance has recently been a growing concern in cattle dairy systems, but few research methodologies are available to address it as a complex problem in a livestock farming system. The aim of this paper is to propose a methodology that combines both systemic and analytical approaches in order to better understand and improve reproductive performance in a cattle dairy system. The first phase of our methodology consists in a systemic approach to build the terms of the problem. It results in formalising a set of potential risk factors relevant for the particular system under consideration. The second phase is based on an analytical approach that involves both analysing the shapes of the individual lactation curves and carrying out logistic...

Wood ash applications to temperate forest ecosystems-potential and drawbacks Inra
Augusto, L.; Bakker, M.R.; Meredieu, C..
The objectives of the present work were (a) to quantify the effects of wood ash on forest ecosystems through a meta-analysis approach associated with a detailed review of the literature (mainly composed of work carried out in Nordic countries) and (b) to extrapolate the effects on forest growth to other contexts (i.e. warm temperate countries) by identifying the cases for which wood ash applications can be beneficial to forest production. Three databases were built regarding the effects of wood ash on soil (151 observations; 33 experimental field trials), on nutrient concentrations of tree foliage (68 observations; 28 trials) and on annual stem biomass growth rate (70 observations; 27 trials). We obtained information on the wide variability of ash...
