Gene body methylation is conserved between plant orthologs and is of evolutionary consequence.

ABSTRACT: DNA methylation is a common feature of eukaryotic genomes and is especially common in noncoding regions of plants. Protein coding regions of plants are often methylated also, but the extent, function, and evolutionary consequences of gene body methylation remain unclear. Here we investigate gene body methylation using an explicit comparative evolutionary approach. We generated bisulfite sequencing data from two tissues of Brachypodium distachyon and compared genic methylation patterns to those of rice (Oryza sativa ssp. japonica). Gene body methylation was strongly conserved between orthologs of the two species and affected a biased subset of long, slowly evolving genes. Because gene body methylation is conserved over evolutionary time, it shapes important features of plant genome evolutio
