Functional Ecology and Genomics

Team EGF objectives are:

  • to acquire knowledge about the structure, function and evolution of genomes of trees (oaks, eucalyptus, pines)
  • to characterize the genetic, physiological and molecular basis of the variability of quantitative traits of economical and ecological interest
  • to characterize the functional strategies of trees in terms of carbon and water relations, dynamics of primary and secondary growth, architectural development of above and below-ground compartments, and apical bud phenology
  • to link the expression of genes / proteins with observable phenotypic characters across the individual to study the molecular basis of plasticity environmental, ontogenetic, and that associated with tissue differentiation
  • to link gene polymorphisms with phenotypic traits at the population level

Taking into account the economic dimension (production, wood quality) and ecological (adaptation) in the management and development of forests, our research will help promote more sustainable management of forests. The magnitude of the task and the complexity of the traits can make a simple single-discipline treatment. Instead, they require close collaborations between geneticists, molecular biologists, and ecophysiologists dendrométriciens within the team EGF, the UMR BIOGECO and well beyond.

Under the proposed research unit project (2011-2014), the team EGF activities are integrated within the main frames :

  • Functions of biodiversity (Population adaptation to environmental contraints)
  • Evolution of biodiversity (Functional strategies and species assemblages)
  • Structure and organisation of biodiversity (Pangenomic and population level distribution of gene nucleotidic polymorphism).

They also contribute to the transverse projects "Phenology" and "Sustainable management of plantation forests".
