In eukaryotes, histone acetylation and deacetylation play an important role in the regulation of gene expression. Histone acetylation levels are reversibly regulated by histone acetyltransferases (HATs) and histone deacetylases (HDACs). Increasing evidence highlights histone acetylation plays essential roles in the regulation of gene expression in plant response to environmental stress. In this review, we discussed the recent advance of histone acetylation in the regulation of abiotic stress responses including temperature, light, salt and drought stress. This information will contribute to our understanding of how plants adapt to environmental changes. As the mechanisms of epigenetic regulation are conserved in many plants, research in this field has potential applications in improvement of agricultural productivity.
在真核生物中，组蛋白乙酰化和去乙酰化在基因表达调控中发挥着重要作用。组蛋白乙酰化水平由组蛋白乙酰转移酶（HATs）和组蛋白去乙酰化酶（HDACs）进行可逆调节。越来越多的证据表明，组蛋白乙酰化在植物对环境胁迫的响应中基因表达调控方面起着至关重要的作用。在本综述中，我们讨论了组蛋白乙酰化在非生物胁迫响应调控方面的最新进展，包括温度、光照、盐和干旱胁迫。这些信息将有助于我们理解植物如何适应环境变化。由于表观遗传调控机制在许多植物中是保守的，该领域的研究在提高农业生产力方面具有潜在应用价值。
