| De l’olivier à l’oléastre : origine et domestication de l’Olea europaea L. dans le Bassin méditerranéen Keywords : VEGETAL PRODUCTIONS, NATURAL RESOURCES AND ENVIRONMENTRésumé : L’olivier occupe la 24 e place des 35 espèces les plus cultivées dans le monde. La diversité phénologique des cultivars est remarquable et l’intérêt économique de l’espèce est majeur. Pourtant peu d’études ont porté sur la domestication de l’olivier et sur les relations entre l’olivier et sa forme sauvage, l’oléastre. Les marqueurs moléculaires rendent possible l’étude de la structure génétique des cultivars, des flux géniques et des relations entre la forme cultivée et sauvage. L’analyse de la diversité actuelle de la sous-espèce europaea d’Olea europea permet de remonter le temps... |

| Monogalactosyldiacylglycerol (MGDG), the major lipid of plant and algal plastids, is synthesized by MGD (or MGDG synthase), a dimeric and membrane-bound glycosyltransferase of the plastid envelope that catalyzes the transfer of a galactosyl group from a UDP-galactose donor onto a diacylglycerol acceptor. Although this enzyme is essential for biogenesis, and therefore an interesting target for herbicide design, no structural information is available. MGD monomers share sequence similarity with MURG, a bacterial glycosyltransferase catalyzing the transfer of N-acetyl-glucosamine on Lipid 1. Using the x-ray structure of Escherichia coli MURG as a template, we computed a model for the fold of Spinacia oleracea MGD. This structural prediction was supported by... |

| 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,... |

| The olive (Olea europaea) and the wattles (mimosas or Acacia spp.) are typical tree species of the Mediterranean and Australia, respectively. Both trees have been subject to trans-oceanic movements, including the introduction of Mediterranean olives to Australia, and the introduction of Australian wattles to the Mediterranean. In each case, the trees have naturalised and become problematic invasives. Based on case studies of such movements, we compare and contrast the processes of transfer, dispersal, and genetic changes of these trees, with particular attention to crop-feral-wild complexes in both their home ranges and in introduced areas. Contrasting ecological, social, and economic landscapes shape the possibilities for crop-feral-wild interactions and... |

| La formation du bois est un processus de développement complexe, impliquant cinqétapes majeures : (1) la division des cellules à partir d’un méristème secondaire, appelé le cambium; (2) l’élongation des cellules ; (3) le dépôt d’une paroi secondaire épaisse ; (4) la mort programmée des cellules ; et (5) leur imprégnation par des composés phénoliques conduisant à la formation du bois de coeur. Grâce au développement des techniques de génomique et aux travaux menés sur la caractérisation d’arbres transgéniques, certains mécanismes moléculaires impliqués dans la formation du bois commencent à être mieux connus. Dans cette revue, deux aspects importants pour la qualité du bois seront approfondis : la lignification et le contrôle de l’angle des microfibrilles... |
