The mutational dynamics of the Arabidopsis centromeres

Nature, Published online: 23 September 2026; doi:10.1038/s41586-026-11046-w Centromeres in Arabidopsis thaliana evolve through frequent insertions and deletions of repeat units and increased rates of point mutations driven by homology-directed repair, a mutation spectrum that is sufficient to generate and maintain large homogenized tandem-repeat blocks.
