Adaptation et acclimatation aux contraintes environnementales abiotique (rayonnement, froid, chaud, salinité) en particulier chez les plantes alpines

J’étudie les mécanismes des plantes modèles qui leur permettent de tolérer les conditions extrêmes du climat. Ces études sont faites en comparaison de plantes cultivées sous conditions contrôlées et exposées au stress contrôlé au laboratoire, par exemple une comparaison entre Arabidopsis thaliana et Thellungiella salsuginea au stress salin. La majorité de travail est faite avec les plantes alpines (Soldanella alpina, Ranunulus glacialis et Geum montanum) dans leur milieu naturel (variation de la température et du rayonnement)

Dans chaque modèle j’étudie la réaction de la photosynthèse au changement extrême du climat. J’étudie le transport électronique, l’utilisation des électrons pour l’assimilation de carbone, la photorespiration et les voies alternatives ainsi que les possibilités de protéger l’appareil photosynthétique par les pigments (flavonoids et caroténoïdes) et l’émission de l’énergie en excès sous forme de chaleur.
