Evolution, mechanisms of feminization and genetic conflicts
in a sex-determining virus
27/06/2025
I'm thrilled that our ViF project has been selected for funding by the ANR. In this project, we will investigate how the first-ever discovered feminizing virus manipulates the sex determination of its host. Our goals are to (1) uncover the virus's origin, (2) understand its mode of action, and (3) assess its impact on the host's evolution—particularly regarding the evolution of sex chromosomes and the selection of sex ratio–distorting suppressor.
Impact of Heat Waves on Symbiotic Interactions Between a Key Soil Macrofauna Species and Its Associated Microorganisms - La Suite
Good news!!!

The University of Poitiers, via the UP² IMPULSIONS call for projects, is also supporting our AramWave project! This new funding will enable us to finance experiments and, above all, to recruit Clarisse Launay for a Master 2 internship.
Impact of Heat Waves on Symbiotic Interactions Between a Key Soil Macrofauna Species and Its Associated Microorganisms
01/07/2024
The Région Nouvelle-Aquitaine has just awarded us substantial funding to investigate the influence of heat waves on symbiotic interactions. In our newly funded project, ArmaWave, we will examine how heat wave exposure affects interactions between a key soil macrofauna species and its various symbionts—some forming part of its digestive microbiota, others known for manipulating host reproduction. Surprisingly, this area of research remains largely unexplored! Thanks to this support, we’ve been able to recruit Théo Ulvé as a PhD student. We’re looking forward to an exciting series of experiments!
A very nice outreach article written by Christa on our study published in ProcB.
