: Our group ‘Organization and evolution of plant genomes’ (OEPG) at URGV studies organization, functioning and evolution of plant genomes; for species such as wheat (Triticum and Aegilops), Brachypodium and Brassica species; in relation to ancient and recent polyploidizations and stresses. Our group has now acquired a recognized experience in transposable element classification (Wicker et al. 2007), annotation and dynamics (Chantret et al. 2005, Charles et al. 2008, Salina et al. 2010, Zhang et al. 2011). We are now conducting a leader research on characterizing genetic and epigenetic effects induced by polyploidy and stresses in wheat and has identified the first mechanisms of polyploidy-related genomic rearrangements, mediated by retrotransposons (Chantret et al., 2005). A particular focus of our group is in the analysis of epigenome and transposable elements (TEs) and their effect on the regulation of the expression of adjacent genes under genomic choc (polyploidy, hybridization) and abiotic (such as drought) stress conditions (Chague et al. 2010, Krugman et al. 2010, , Chalhoub et al. 2014).
