Centromeres are critical for maintaining genomic stability in eukaryotes, and their turnover can shape genome architectures and drive karyotype evolution. However, the co-evolution of centromeres from different species in allopolyploids over millions of years remains largely unknown. Here, we constructed three near-complete genome assemblies for B. hybridum, B. distachyon, and B. stacei, and provided the first comprehensive comparison of previously inaccessible centromeric regions across species with different polyploidy levels. Our findings offer novel scientific insights into the sequences, structural, and epigenetic variations in centromeres of closely related species, and their potential roles during polyploidy adaptions at base-pair resolution. |
