摘要

表观遗传修饰是一种可遗传、可逆的变化,它在不改变 DNA 序列本身的情况下控制基因的表达。表观遗传学和测序技术的最新进展揭示了具有多种表观遗传学变化的基因中的关键调控区域。然而,表观遗传变化与生理事件之间的因果关系却很少得到研究。表观基因组编辑可以在不改变底层 DNA 序列的情况下改变表观基因组。修改植物的表观遗传信息对表观基因组的因果关系评估具有重要意义。在此,我们简要回顾了选择性研究表观基因组的工具。我们重点介绍了在特定位点 DNA 甲基化和组蛋白修饰方面前景广阔的研究,并提出了未来的研究方向,以更深入地研究表观遗传调控,包括表观遗传修饰与拟南芥发育/环境反应之间的因果关系。

Cause or effect: Probing the roles of epigenetics in plant development and environmental responses

Epigenetic modifications are inheritable, reversible changes that control gene expression without altering the DNA sequence itself. Recent advances in epigenetic and sequencing technologies have revealed key regulatory regions in genes with multiple epigenetic changes. However, causal associations between epigenetic changes and physiological events have rarely been examined. Epigenome editing enables alterations to the epigenome without changing the underlying DNA sequence. Modifying epigenetic information in plants has important implications for causality assessment of the epigenome. Here, we briefly review tools for selectively interrogating the epigenome. We highlight promising research on site-specific DNA methylation and histone modifications and propose future research directions to more deeply investigate epigenetic regulation, including cause-and-effect relationships between epigenetic modifications and the development/environmental responses of Arabidopsis thaliana.
