Diversity of cytosine methylation across the fungal tree of life.

ABSTRACT: The generation of thousands of fungal genomes is leading to a better understanding of genes and genomic organization within the kingdom. However, the epigenome, which includes DNA and chromatin modifications, remains poorly investigated in fungi. Large comparative studies in animals and plants have deepened our understanding of epigenomic variation, particularly of the modified base 5-methylcytosine (5mC), but taxonomic sampling of disparate groups is needed to develop unifying explanations for 5mC variation. Here, we utilize the largest phylogenetic resolution of 5mC methyltransferases (5mC MTases) and genome evolution to better understand levels and patterns of 5mC across fungi. We show that extant 5mC MTase genotypes are descendent from ancestral maintenance and de novo genotypes, where
