Abstract: Chemical modification of DNA bases in recent years has been one of the hot areas of life science research. DNA methylation is a common epigenetic phenomenon and can change the genetic performance without changing the DNA sequence. Various stress factors can induce the variation of DNA methylation in plants, but the response mechanism is still unknown. In this paper, the progress of DNA methylation in plants was reviewed. In combination with the researchconclusions of our own research group, the DNA methylation variation induced by 7Li ion beam and gamma ray was reported to provide a basis for DNA methylation, which may be involved in the phenotypic plasticity of plants.
