作为固着生物，植物在其生命周期中会遇到各种环境刺激，包括非生物胁迫。为了在不利条件下生存，植物进化出了复杂的机制来感知外部信号并做出相应的反应。对各种胁迫的反应很大程度上取决于植物快速、特异性调节转录组的能力。大量研究表明，驱动植物应对环境胁迫的分子机制通常取决于核小体组蛋白翻译后修饰，包括组蛋白乙酰化、甲基化、泛素化和磷酸化。这些修饰的综合作用在应激反应基因表达的调节中发挥着重要作用。在这篇综述中，我们强调了我们目前对组蛋白修饰的表观遗传机制及其在植物非生物胁迫反应中的作用的理解。
As sessile organisms, plants encounter various environmental stimuli including abiotic stresses during their lifecycle. To survive under adverse conditions, plants have evolved intricate mechanisms to perceive external signals and respond accordingly. Responses to various stresses largely depend on the plant capacity to modulate the transcriptome rapidly and specifically. A number of studies have shown that the molecular mechanisms driving the responses of plants to environmental stresses often depend on nucleosome histone post-translational modifications including histone acetylation, methylation, ubiquitination, and phosphorylation. The combined effects of these modifications play an essential role in the regulation of stress responsive gene expression. In this review, we highlight our current understanding of the epigenetic mechanisms of histone modifications and their roles in plant abiotic stress response.
