Genetic basis of local adaptation

Molecular Ecology

Local adaptation represents the first step to speciation and therefore to biological diversification. Elucidating the genetic mechanisms underlying this process therefore constitutes a key question in the field of evolutionary biology. Mutations as well as chromosome rearrangements have been shown to be involved in this evolutionary process. However, to what extent other sources of genetic variation influence the evolution of natural populations remains poorly understood. To this regard, the aim of our project is to better understand how transposable element activation contributes to the evolution of natural populations, using Brachypodium distachyon as a model.
