Demethylation activates TEs in companion cells and reinforces methylation in sperm. (A) DME-dependent demethylation of TEs that are maternally expressed in wild-type, but not dme, endosperm (table S4). DMRs (table S2) are underlined. (B) Kernel density plots of the CHH methylation differences between sperm cells from wild-type and dme/+ plants. (C) Kernel density plots of the CG methylation differences between vegetative cells from wild-type and dme/+ plants. (D) Snapshots of CG and CHH methylation in pollen on chromosome 1. Arrows point out loci with decreased CHH methylation in sperm and increased CG methylation in vegetative cells from dme/+ pollen.
