Dynamic patterns of repeats and retrotransposons in the centromeres of Humulus lupulus L.
New Phytologist, Volume 247, Issue 6, Page 2766-2780, September 2025.Summary The centromere has a conserved function across eukaryotes; however, the associated DNA sequences exhibit remarkable diversity in both size and structure. In plants, some species possess well‐defined centromeres dominated by tandem satellite repeats and centromeric retrotransposons, while others have centromeric regions composed almost entirely ...
