Main research interests

My research activity is mainly focused on germination and seed vigour issues. Germination can be limited by seed dormancy state and/or by penalizing environmental conditions. In addition, seed viability is a fundamental trait to take into account in the strategies of biodiversity conservation. I developed an expertise in functional genomics (transcriptome, proteome) and metabolomics with a focus on the molecular mechanisms controlling seed germination and the characterization of quality markers of seed vigor. I developed a solid expertise in integrative proteomics, notably to investigate seed physiology using 2D-protein electrophoresis and mass spectrometry. I developed analysis of protein turnover (pulse labeling) and post-translational modifications (e.g. carbonylation, S-nitrosylation, tyrosine nitration).
