Abstract

The advent of high-throughput sequencing-based methods for chromatin conformation, accessibility, and immunoprecipitation assays has been a turning point in 3D genomics. Altogether, these new tools have been pushing upward the interpretation of pioneer cytogenetic evidence for a higher order in chromatin packing. Here, we review the latest development in our understanding of plant spatial genome structures and different levels of organization and discuss their functional implications. Then, we spotlight the complexity of organellar (i.e., mitochondria and plastids) genomes and discuss their 3D packing into nucleoids. Finally, we propose unaddressed research axes to investigate functional links between chromatin-like dynamics and transcriptional regulation within organellar nucleoids.

植物三维基因组组织的空间特征及其功能意义
基于高通量测序的染色质构象、可及性和免疫沉淀测定方法的出现是3D基因组学的一个转折点。总的来说,这些新工具已经推动了对染色质包装更高阶的先驱细胞遗传学证据的解释。本文综述了植物空间基因组结构和不同层次组织的最新进展,并讨论了它们的功能意义。然后,我们聚焦细胞器(即线粒体和质体)基因组的复杂性,并讨论它们的三维包装成类核。最后,我们提出了未解决的研究轴,以研究细胞器类核内染色质样动力学和转录调控之间的功能联系。
