GenomicsGenome-wide demethylation of Arabidopsis endosperm
Parent-of-origin-specific (imprinted) gene expression is regulated in Arabidopsis thaliana endosperm by cytosine demethylation of the maternal genome mediated by the DNA glycosylase DEMETER, but the extent of the methylation changes is not known.  Here we show that virtually the entire endosperm gen...

GenomicsDDM1 and RdDM are the major regulators of transposon DNA methylation in Arabidopsis
Eukaryotic DNA methylation is found in silent transposable elements and active genes. Nucleosome remodelers of the DDM1/Lsh family are thought to be specifically required to maintain transposon methylation, but the reason for this is unknown. Here, we find that a chromatin gradient that extends from...

TranscriptomicsGenome-wide evolutionary analysis of eukaryotic DNA methylation
Eukaryotic cytosine methylation represses transposable elements, but also occurs in bodies of active genes. The extent to which these processes are conserved is unclear, and little is known about methylation outside of mammals, Arabidopsis thaliana, and Neurospora crassa. Utilizing deep bisulfite se...

GenomicsLocal DNA hypomethylation activates genes in rice endosperm
Cytosine methylation silences transposable elements in plants, vertebrates and fungi, but also regulates gene expression1. Plant methylation is catalyzed by three families of enzymes, each with a preferred sequence context: CG, CHG (H = A, C or T) and CHH, with CHH methylation targeted by the RNA in...
