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.
摘要
我们报告了与三个马铃薯染色体着丝粒相关的不同单倍型的发现，包括由长串联卫星重复序列组成的单倍型和缺乏相同重复序列的单倍型。这些结果支持了这样的假设，即基于卫星重复序列的着丝粒可能起源于缺乏重复序列的新着丝粒。
