环境诱导的DNA甲基化及其可遗传性研究

NA methylation is an important mechanism of epigenetic modifications, which is able to regulate physiological activity by affecting gene transcription and expression, and has important significance for plant to response and adaptation to changing environment. This paper firstly introduced the implication of DNA methylation, the analysis techniques and statistical calculating method of data, reviewed focusing on the relationship between reversible and heritable, genetic variation of DNA sequence and epigenetic variation of DNA methylation in plant, and then discussed the adaptive value and evolutionary significance of DNA methylation.
