摘要

乙烯是一种重要的植物激素，控制着过多的植物发育和胁迫反应。因此，乙烯信号的产生和发展必须受到严格的时空控制。本文综述了在理解表观遗传机制如何控制乙烯生物合成和信号传导，以及乙烯介导的表观遗传修饰子如何反过来控制基因表达和生物过程方面的最新里程碑。我们讨论了乙烯控制的组蛋白乙酰化对乙烯信号进展至关重要的中心机制。此外，我们概述了广泛的表观遗传机制如何控制乙烯介导的发育和胁迫反应，重点是水果成熟。最后，提出了乙烯信号在植物表观遗传机制中的整合研究方向和有待解决的问题。

Ethylene signal integration through epigenetic mechanisms in plants

Ethylene is an essential phytohormone that controls a plethora of plant developmental and stress responses. Accordingly, ethylene signal generation and progression must be under tight spatiotemporal control. This review highlights the latest milestones in understanding how epigenetic mechanisms govern ethylene biosynthesis and signaling, and how ethylene-mediated recruitment of epigenetic modifiers in turn controls gene expression and biological processes. We discuss a central mechanism of how ethylene-controlled histone acetylation is essential for ethylene signal progression. In addition, we outline how a wide range of epigenetic mechanisms control ethylene-mediated developmental and stress responses, with a focus on fruit ripening. Finally, we propose future research directions and open questions of ethylene signal integration through epigenetic mechanisms in plants.
