Genome-Wide Epigenetic Regulation of Gene Transcription in Maize Seeds.

ABSTRACT:

Background

Epigenetic regulation is well recognized for its importance in gene expression in organisms. DNA methylation, an important epigenetic mark, has received enormous attention in recent years as it's a key player in many biological processes. It remains unclear how DNA methylation contributes to gene transcription regulation in maize seeds. Here, we take advantage of recent technologies to examine the genome-wide association of DNA methylation with transcription of four types of DNA sequences, including protein-coding genes, pseudogenes, transposable elements, and repeats in maize embryo and endosperm, respectively.

Results

The methylation in CG, CHG and CHH contexts plays different roles in the control of gene expression. Methylation around the transcription start si
