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.
