High-throughput sequencing of methylated cytosine enriched by modification-dependent restriction endonuclease MspJI.

ABSTRACT:

Background

As a well-known epigenomic modification, DNA methylation is found to be common in plants and plays an important role in many biological processes. Relying on the unique feature of methylation-dependent digestion, the family of methylation-requiring restriction-like endonuclease, such as MspJI and its homologs, was suggested for a potential usage in methylation detection.

Results

In this study, we combine MspJI digestion and electrophoretic band selection with next generation high-throughput sequencing technology to detect 5-methylcytosines in Arabidopsis genome. By developing a bioinformatics workflow to attribute the CNNR sites recognized by MspJI to the reference genome, we fulfilled the systematic assessment of this method.
