摘要

多聚核糖体组（PcG）组蛋白修饰系统是维持基因抑制的关键，可提供有丝分裂遗传的细胞记忆。然而，为了让植物在发育过程中过渡到不同的转录程序或对外部线索做出反应，PcG 介导的抑制需要可逆性。一些数据表明，在不同的细胞环境中，PcG 标记的动态可能会有很大不同；然而，PcG 标记在每种情况下是如何建立、维持或去除的，目前还不清楚。在这篇综述中，我们将对不同细胞阶段 PcG 标记的维持或更替的分子机制进行已知和未知的调查。

Dynamics of polycomb group marks in Arabidopsis

Polycomb Group (PcG) histone-modifying system is key in maintaining gene repression, providing a mitotically heritable cellular memory. Nevertheless, to allow plants to transition through distinct transcriptional programs during development or to respond to external cues, PcG-mediated repression requires reversibility. Several data suggest that the dynamics of PcG marks may vary considerably in different cell contexts; however, how PcG marks are established, maintained, or removed in each case is far from clear. In this review, we survey the knowns and unknowns of the molecular mechanisms underlying the maintenance or turnover of PcG marks in different cell stages.
