Abstract:

DNA methylation can change gene expressions and cause variable splicing without any alterations in the DNA sequence, thus changing cell phenotype and even function; moreover, this modification can be transmitted to progeny DNA during the process of DNA replication and plays an important regulatory role in plant somatic mutation. Moso bamboo(Phyllostachys edulis)is mainly propagated by vegetative process, however, it has abundant natural mutation types, and the underlying genetic regulation mechanism is not clear so far. In this paper, we reviewed the advances of natural variation in Moso bamboo, DNA methylation and its transcriptional regulation in plant development, and prospected the potential application of DNA methylation in bamboo natural variation, aiming to provide theoretical guidance and technical support for accurate breeding of bamboo plants.

Key words: epigenetic transcription regulation, DNA methylation, differentiation and development, natural variation, bamboo
