The centromere and telomere are universal heterochromatic domains; however, the proper positioning of those domains in nuclear space during the mitotic interphase differs among eukaryotes. Consequently, the question arises how and why this difference occurs. Studies over the past 2 decades have identified several nuclear membrane proteins, nucleolar proteins, and the structural maintenance of a chromosome complex as factors involved in the positional control of centromeres and/or telomeres during the mitotic interphase in yeasts, animals, and plants. In this review, with a primary focus on plants, the roles of those factors are summarized, and the biological significance of proper centromere and telomere positionings during the mitotic interphase is discussed in an effort to provide guidance for this question.

植物着丝粒和端粒位置控制的机理和意义。

着丝粒和端粒是通用的异色域；然而，真核生物在有丝分裂间期中这些区域在核空间中的正确定位有所不同。因此，出现了一个问题，即如何以及为什么会出现这种差异。过去20年的研究已经确定了几种核膜蛋白，核仁蛋白和染色体复合物的结构维持是在酵母，动物和植物的有丝分裂中间相期间着丝粒和/或端粒的位置控制中涉及的因素。在这篇综述中，主要着眼于植物，总结了这些因素的作用，并讨论了在有丝分裂间期适当的着丝粒和端粒定位的生物学意义，以期为该问题提供指导。
