In recent years, the study of plant three-dimensional nuclear architecture received increasing attention. Enabled by technological advances, our knowledge on nuclear architecture has greatly increased and we can now access large data sets describing its manifold aspects. The principles of nuclear organization in plants do not significantly differ from those in animals. Plant nuclear organization comprises various scales, ranging from gene loops to topologically associating domains to nuclear compartmentalization. However, whether plant three-dimensional chromosomal features also exert similar functions as in animals is less clear. This review discusses recent advances in the fields of three-dimensional chromosome folding and nuclear compartmentalization and describes a novel silencing mechanism, which is closely linked to nuclear architecture.

近年来，植物三维核结构的研究日益受到重视。随着技术的进步，我们对核结构的知识大大增加，我们现在可以访问描述其多方面特征的大数据集。植物中的核组织原理与动物中的核组织原理没有显着差异。植物核组织包括从基因环到拓扑关联域到核区室化的各种规模。但是，尚不清楚植物的三维染色体特征是否也具有与动物相似的功能。这篇综述讨论了三维染色体折叠和核区室化领域的最新进展，并描述了一种与核结构密切相关的新型沉默机制。
