| Abstract: | Epigenetics plays an important role in plant development. DNA methylation is one of the most common epigenetic modification. In this paper, the current achievements in the study of the phenomena of the methylation of cytosines, the signals for DNA methylation, RNA-directed DNA methylation patterning, the differences between the RNAi and epigenetic control of transposons via RNA were reviewed. |

| Keywords: | epigenetic DNA methylation cytosine methyltransferase gene silencing |
