Desiccation and stress responses

Main research interests

The activities of my group are focused on the signaling role of reactive oxygen species and on the role of post-transcriptional mechanisms in the regulation of seed germination and dormancy. Our objectives are to decipher the oxidative mechanisms involved in the transduction of exogenous (temperature and oxygen) or endogenous (eg hormones) signals that regulate seed germination and to determine whether progress towards seed germination is associated with changes in mRNA processing, translatome profile and post-translational protein modifications. In addition the team has a strong experience in translational biology which ensures a rapid transfer of our findings towards the stakeholders.
