This project will contribute to the identification of functionally important genes and the validation of the mutations (SNPs) within such genes of adaptive value, concluding from their associations with the phenotypic variation of adaptive traits. The project will focus on both structural and regulatory "candidate" genes underlying forest trees adaptation and potentially involved in bud phenology (Quercus petraea) and drought stress response (Pinus pinaster). In practice, the results will be germane to conservation programs, where information on the genetic control of the physiological functions of trees will aid to preserve critically important genotypes. Another important area of application for functional genomics in particular is adaptation of trees to environmental changes of all sorts, and physiological responses to abiotic stress. Given the large number of genes under study (about one hundred) and their nature (structural vs. regulatory), it is expected that the benefit of the project will exceed the studied species and traits, both with respect to the type of genes or mutations of adaptive value, and the methodology and molecular criteria necessary to assess adaptive diversity in plant species.
