Abstract:

DNA methylation is the most important way of epigenetics, which plays an important role in gene expression, plant development and micropropagation. This paper introduced the progress of DNA methylation in tree development and micropropagation, including the DNA methylation patterns reconstruction between different development stages, such as age, flowering, dormancy, education and sex of woody plants, and the DNA methylation patterns reconstruction in the callus subculture, the formation of regenerated plants and somatic embryogenesis. Last, the relationship between hybridization and DNA methylation was reviewed, and then prospected the current research.
