摘      要：DNA methylation and histone modification are evolutionarily conserved epigenetic modifications that are crucial for the expression regulation of abiotic stress-responsive genes in *** changes in gene expression levels can result from changes in DNA methylation and histone *** the last two decades,how epigenetic machinery regulates abiotic stress responses in plants has been extensively ***,based on recent publications,we review how DNA methylation and histone modifications impact gene expression regulation in response to abiotic stresses such as drought,abscisic acid,high salt,extreme temperature,nutrient deficiency or toxicity,and ultraviolet B *** also review the roles of epigenetic mechanisms in the formation of transgenerational stress *** posit that a better understanding of the epigenetic underpinnings of abiotic stress responses in plants may facilitate the design of more stress-resistant or-resilient crops,which is essential for coping with global warming and extreme environments.
