Epigenetic mechanisms are integral to plant growth, development, and adaptation to environmental stimuli. Over the past two decades, our comprehension of these complex regulatory processes has expanded remarkably, producing a substantial body of knowledge on both locus-specific mechanisms and genome-wide regulatory patterns. Studies initially grounded in the model plant Arabidopsis have been broadened to encompass a diverse array of crop species, revealing the multifaceted roles of epigenetics in physiological and agronomic traits. With recent technological advancements, epigenetic regulations at the single-cell level and at the large-scale population level are emerging as new focuses. This review offers an in-depth synthesis of the diverse epigenetic regulations, detailing the catalytic machinery and regulatory functions. It delves into the intricate interplay among various epigenetic elements and their collective influence on the modulation of crop traits. Furthermore, it examines recent breakthroughs in technologies for epigenetic modifications and their integration into strategies for crop improvement. The review underscores the transformative potential of epigenetic strategies in bolstering crop performance, advocating for the development of efficient tools to fully exploit the agricultural benefits of epigenetic insights.
表观遗传机制对于植物的生长、发育以及适应环境刺激至关重要。在过去二十年中，我们对这些复杂调控过程的理解有了显著扩展，产生了大量关于基因座特异性机制和全基因组调控模式的知识。最初基于模式植物拟南芥的研究已扩展到涵盖多种作物物种，揭示了表观遗传学在生理和农艺性状中的多方面作用。随着近期技术的进步，单细胞水平和大规模群体水平的表观遗传调控正成为新的研究重点。本综述对多种表观遗传调控进行了深入综合，详细阐述了催化机制和调控功能。它深入探讨了各种表观遗传元件之间的复杂相互作用及其对作物性状调控的综合影响。此外，它还研究了表观遗传修饰技术的最新突破及其在作物改良策略中的整合。该综述强调了表观遗传策略在提升作物性能方面的变革潜力，倡导开发有效工具以充分利用表观遗传学见解带来的农业益处。
