Abstract

Plant centromeres are generally composed of tandem arrays of simple repeats that are typical of a particular species, but that evolve rapidly. Centromere specific retroelements are also present. These arrays associate with a centromere specific variant of histone H3 that anchors the site of the kinetochore. Although such DNA arrays are typical of the centromere, the specification of centromere activity has an epigenetic component as shown by the fact that centromeres are formed in the absence of such repeats and that centromeres in dicentric chromosomes regularly undergo inactivation.

植物着丝粒。
植物着丝粒通常由简单重复序列的串联阵列组成,这是特定物种的典型特征,但进化速度很快。着丝粒特有的逆转录因子也存在。这些阵列与固定着丝点位置的组蛋白H3的着丝粒特异性变体相关联。虽然这样的DNA排列是着丝粒的典型特征,但着丝粒活性的规范具有表观遗传成分,这一事实表明,着丝粒是在没有这种重复的情况下形成的,而双中心染色体中的着丝粒有规律地经历失活。
