How chromatin changes shift CHH methylation pathways in soybean
Plant Science Research WeeklyDECREASED IN DNA METHYLATION 1 (DDM1) is a chromatin remodeler that regulates nucleosome organization and facilitates access of DNA methyltransferases to heterochromatic regions enriched in transposable elements (TEs), contributing to DNA methylation, TE silencing, and genome stability. In plants, CHH…
