Associate Professor

Loïc Rajjou
Dormancy, germination and dispersal

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).
