  abstract = {{U}nderstanding how plants adapt to changing environments and the potential contribution of transposable elements ({TE}s) to this process is a key question in evolutionary genomics. {W}hile {TE}s have recently been put forward as active players in the context of adaptation, few studies have thoroughly investigated their precise role in plant evolution. {H}ere, we used the wild {M}editerranean grass {B}rachypodium distachyon as a model species to identify and quantify the forces acting on {TE}s during the adaptation of this species to various conditions, across its entire geographic range. {U}sing sequencing data from more than 320 natural {B}. distachyon accessions and a suite of population genomics approaches, we reveal that putatively adaptive {TE} polymorphisms are rare in wild {B}. distachyon populations. {A}fter accounting for changes in past {TE} activity, we show that only a small proportion of {TE} polymorphisms evolved neutrally (<10%), while the vast majority of them are under moderate purifying selection regardless of their distance to genes. {TE} polymorphisms should not be ignored when conducting evolutionary studies, as they can be linked to adaptation. {H}owever, our study clearly shows that while they have a large potential to cause phenotypic variation in {B}. distachyon, they are not favored during evolution and adaptation over other types of mutations (such as point mutations) in this species.},
