RNA triple helix assembled by the poly(A) tail enhances retrotransposon mobilization by preventing RNA deadenylation

Proceedings of the National Academy of Sciences, Volume 122, Issue 39, September 2025. <br/>SignificanceTransposable elements (TEs) are pieces of DNA that can move within a genome, though cells usually suppress them. In the plantArabidopsis, one active TE calledCopia93, orEvade, remains highly mobile. We found that a region in its RNA, the …
