Activités de recherche :

The research interests are ascribed to the agricultural context for the sustainable production of forage crops under the stressed conditions. The primary works with white clover had been carried out to characterize the physiological responses to water-deficiency: 1) De novo synthesis of amino acids and proteins, and the hydrolysis of protein and starch reserves under water-deficiency, 2) drought-induced oxidative stress and the activation of antioxidant enzymes, 3) kinetics of drought-induced pathogenesis-related (PR) proteins 4) kinetics of peroxidases and its involvement in lignification in relation to the intensity of water-deficit stress. These results lead to challenges encountered in the stress tolerance mechanism. Starting from March 2010, the projects have been directed to two main research interests.

The first is a complementary analysis of plant responses to any possible stress factors for an ultimate understanding of stress tolerance mechanism. The current works pay attention to determine particularly the changes in the morphology and function of the photosynthetic organelles (chloroplast thylakoid protein complexes) and the modification S metabolism with interaction of N.

The second, with an extra importance, is the investigation of physiological significance of sulfur (S) nutrition in stress tolerance. The current research topics are following: (i) Involvement of S nutrition in modulating iron deficiency responses in photosynthetic organs, (ii) S nutrition involves in modulating N metabolism under iron deficiency in oilseed rape plants, and (iii) S nutrition effects on ethylene production and their significance in stress tolerance in oilseed rape plants
