In eukaryotic cells, gene expression is greatly influenced by the dynamic chromatin environment. Epigenetic mechanisms, including covalent modifications to DNA and histone tails and the accessibility of chromatin, create various chromatin states for stress‐responsive gene expression that is important for adaptation to harsh environmental conditions. Recent studies have revealed that many epigenetic factors participate in abiotic stress responses, and various chromatin modifications are changed when plants are exposed to stressful environments. In this review, we summarize recent progress on the cross‐talk between abiotic stress response pathways and epigenetic regulatory pathways in plants. Our review focuses on epigenetic regulation of plant responses to extreme temperatures, drought, salinity, the stress hormone abscisic acid, nutrient limitations and ultraviolet stress, and on epigenetic mechanisms of stress memory.

植物非生物胁迫响应中的表观遗传调控。

在真核细胞中，基因表达受到动态染色质环境的极大影响。表观遗传机制包括对DNA和组蛋白尾巴的共价修饰以及染色质的可及性，为应激反应性基因表达创造了各种染色质状态，这对于适应恶劣的环境条件非常重要。最近的研究表明，许多表观遗传因素参与非生物胁迫响应，当植物暴露于胁迫环境时，各种染色质修饰会发生变化。在这篇综述中，我们总结了植物非生物胁迫响应途径与表观遗传调控途径之间相互影响的最新进展。我们的研究重点是植物对极端温度，干旱，盐度，胁迫激素脱落酸，
