Ecological Genomics of Polyploids

Colonization of alpine landscapes by Buckler mustards is associated with recurrent whole genome duplications, dynamics of transposable elements and adaptive evolution of stress-responding genes. Although consistent with evolutionary diversification proceeding through the adaptive recruitment of innovative mutations under environmental challenges, much remains to be understood regarding the underlying molecular and ecological ramifications.

We are using natural as well as experimental populations of diploids and autopolyploids to infer the dynamics of duplicated genes in interaction with transposable elements and the environment to integrate the underpinnings of genome evolution in contrasted habitats.
