Three Potato Centromeres Are Associated with Distinct Haplotypes with or Without Megabase-Sized Satellite Repeat Arrays

Abstract

We report discoveries of different haplotypes associated with the centromeres of three potato chromosomes, including haplotypes composed of long arrays of satellite repeats and haplotypes lacking the same repeats. These results are in favor of the hypothesis that satellite repeat-based centromeres may originate from neocentromeres that lack repeats.
