Relaxed purifying selection in autopolyploids drives transposable element over-accumulation which provides variants for local adaptation
Why transposable elements (TEs) accumulate in polyploids and the evolutionary implications remain unclear. Here, the authors show that following whole genome duplication, relaxed purifying selection is the main driver of TE over-accumulation, which provides variants for rapid local adaptation.
