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，植物三维核构象的研究受到了越来越多的关注。随着技术的进步，我们对核构象的认识有了很大的提高，现在我们可以获得描述其多方面的大量数据集。植物中核组织的原则与动物的没有显著差异。植物的核组织包括各种尺度，从基因环到拓扑关联域到核区室化。然而，植物三维染色体特征是否也具有与动物相似的功能尚不清楚。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，并描述了一种与核构象密切相关的新型沉默机制。
