Repeat Dynamics across Timescales : A Perspective from Sibling Allotetraploid Marsh Orchids (Dactylorhiza majalis s.l.)
To provide insights into the fate of transposable elements (TEs) across timescales in a post-polyploidization context, we comparatively investigate five sibling Dactylorhiza allotetraploids (Orchidaceae) formed independently and sequentially between 500 and 100K generations ago by unidirectional hybridization between diploids D. fuchsii and D. incarnata. Our results first reveal that the paternal
