Research Topic

I first worked on various aspects of plant development in Arabidopsis thaliana (chloroplast / meristem / gametophyte). Then, in 2008, I moved to Avignon to join the Resistance to Virus team at INRAE.  I am now leading the  ReDD team with Véronique Lefebvre.

Our research is focussed on developping genetic resistances to viruses in plants.

To successfully infect plants, viruses have to hijack host factors. Those can be turned into genetic resistances by making them unavailable to the pathogens. We aim at characterizing plant susceptibility factors in plants and develop genetic resistances to viruses of agricultural importance. We are particularly interested in assessing how genome editing technologies can be used to copy mutations across species and develop resistances.
