Imprinting: DNA methyltransferases illuminate reprogramming

Joseph P Calarco et al. Curr Biol. .

Abstract

Progress in studying epigenetic reprogramming in plants has been impeded by the difficulty in obtaining tissue for analysis. Now, using a combination of fluorescent reporters and translational fusions, a new study sheds some light on this process.

DNA methylation dynamics through embryo development. A graphical representation of DNA methylation levels as the embryo develops as seen in Jullien et al. [4] CG (red) and CHG (blue) levels appear relatively constant over the few loci examined, while CHH methylation (green) appears to progressively increase methylation from the early/late globular stage to the heart and green torpedo stages.
