Abstract

Epigenetics is the study of hereditary changes in gene expression under the premise that the nucleotide sequence is not changed. Such hereditary changes mainly involve DNA methylation, histone modification, and chromatin remodeling. These covalent modifications play indispensable roles in regulating gene expression; DNA replication, recombination, and repair; and cell differentiation. Epigenetic modifications can be partially inherited by daughter cells during mitosis and meiosis and influenced by external factors, such as environmental stresses and supply deficits. In this review, we summarize the current knowledge regarding epigenetic factors, such as DNA methylation, histone acetylation, and regulation by non-coding RNAs, in the development and stress response of plants.

表观遗传修饰在植物逆境反应中的作用

表观遗传学是在核苷酸序列不变的前提下研究基因表达的遗传变化的学科。这些遗传变化主要包括DNA甲基化、组蛋白修饰和染色质重塑。这些共价修饰在基因表达调控中起着不可或缺的作用;DNA复制、重组和修复;细胞分化。表观遗传修饰在有丝分裂和减数分裂期间可部分由子细胞遗传，并受外部因素(如环境胁迫和供应不足)的影响。本文就DNA甲基化、组蛋白乙酰化、非编码rna调控等表观遗传因素在植物发育和胁迫反应中的作用进行综述。
