Genome-Wide Identification and Comparative Analysis of Cytosine-5 DNA Methyltransferase and Demethylase Families in Wild and Cultivated Peanut.

ABSTRACT: DNA methylation plays important roles in genome protection, regulation of gene expression and is associated with plants development. Plant DNA methylation pattern was mediated by cytosine-5 DNA methyltransferase and demethylase. Although the genomes of AA and BB wild peanuts have been fully sequenced, these two gene families have not been studied. In this study we report the identification and analysis of putative cytosine-5 DNA methyltransferases (C5-MTases) and demethylases in AA and BB wild peanuts. Cytosine-5 DNA methyltransferases in AA and BB wild peanuts could be classified in MET, CMT, and DRM2 groups based on their domain organization. This result was supported by the gene and protein structural characteristics and phylogenetic analysis. We found that some wild peanut DRM2 members
