Genetic x Environment interactions in plant metabolic plasticity

Genetic bases of metabolic traits have been studies in several plant species. However, their understanding is restricted to few molecular mechanisms which cannot explain the wide phenotypic plasticity linked to these kinds of traits, especially when genotypes are exposed to extreme environments. Our research group is focused on (epi)genetic factors determining biochemical processes in harvestable organs of main Solanaceae species (tomato, potato, tobacco). In this talk I discuss results coined from i) analyses of the epigenetic nature of metabolic content regulation in the fruit of tomato, particularly in the vitamin E biosynthesis and ii) analyses of perturbations on gene expression linked to genomic stress associated to hybridization between divergent genotypes and their relations with hybrid vigor (heterosis) in higher plants.
