2012-2015 : Projet FLAG financé par l’ANR « FOREST TREE ECOLOGICAL GENETICS : INTERPLAY OF GENE FLOW AND ENVIRONMENTAL VARIABILITY IN SHAPING LOCAL ADAPTATION AND GENETIC ADAPTIVE POTENTIAL ». Responsable scientifique UMR Biogeco : Christophe Plomion. 5 partenaires : INRA ECOFOG, INRA URFM, CIFOR-INIA, Universidade federal de Goias, INRA AGPF, INRA Biogeco, CNR-IGV.
The project propose here to address the genetic response of forest tree populations to gradients and habitat contrasts related to soil water content (SWC) and temperature. These gradients are major determinants of tree growth and survival, and the physiological and molecular properties of plant responses to heat, cold, drought and flooding stress are among the most finely characterised processes in plant biology. Therefore, studying evolutionary-genetic patterns related to these stresses in natural populations of non-model organisms will take advantage of the field’s large body of knowledge. The fact that such environmental gradients are relevant in tree populations is proven by several case studies reporting survival and growth response to changes in temperature and SWC.
