Présentation
My research aims to uncover the processes that generate genome variation and to understand how these processes shape microbial adaptation. My team focuses on Plasmopara viticola, the grapevine downy mildew pathogen, which is engaged in a co-evolutionary arms race with its hosts. We use population genomics approaches to study diversity across populations at different environmental scales. Recently, we described the first genetic determinants (avirulence genes) that drive P. viticola interactions with grapevine, and we characterize the diversity and evolution of effectors mediating pathogen-host interactions. This knowledge contributes to the sustainable management of plant genetic resistance. The second goal of my research is to integrate evolutionary and ecological perspective into the management of plant diseases. Population genetics provides a theoretical framework for designing strategies that limit the emergence and spread of genotypes with major agronomic impact. My aim is therefore to generate knowledge and develop tools that support sustainable, agroecological strategies for vineyard protection. This includes innovative preventive management approaches based on the diruption of the pathogen’s sexual cycle.
