表观遗传调控植物响应非生物胁迫的研究进展

植物的生长发育容易受到外界环境变化的影响。非生物胁迫发生时, 表观遗传机制对胁迫应答基因的表达调控发挥了十分重要的作用。近年来, 调控植物非生物胁迫应答的表观遗传机制研究取得了一系列重要进展, 为进一步深入解析植物响应非生物胁迫的分子机制奠定了基础。该文对DNA甲基化修饰、组蛋白修饰、染色质重塑和非编码RNA等主要表观遗传调控方式在植物响应非生物胁迫中的作用进行了简要综述。

Advances in Epigenetic Regulation of Abiotic Stress Response in Plants

Plant growth and development are easily affected by environmental changes, and epigenetic mechanisms play important roles in regulating gene expression in response to environmental stimuli. In recent years, epigenetic stu- dies have achieved important progress in the response to abiotic stresses in plants, providing a good foundation for further understanding the potential molecular mechanisms. In this review, we summarize the plant epigenetic regulations, including DNA methylation, histone modification, chromatin remodeling and small RNA, in response to abiotic stresses.
