Genome dynamics and speciation
Research in my group deals with the association between genome evolution and plant diversification under environmental changes.
Our current projects are focused on the role of jumping genes (i.e. transposable elements) on structural and functional changes across the genome, and their impact on reproductive isolation in natural plant populations.
We mainly use polyploid speciation (i.e. merging of genomes associated with multiplication of chromosome sets at the origin of new species) as a model process. Polyploidy indeed is a revolutionary event inducing drastic changes in both genome organization and ecological properties of nascent lineages.
