tailieunhanh - Embryo CHH hypermethylation is mediated by RdDM and is autonomously directed in Brassica rapa

RNA-directed DNA methylation (RdDM) initiates cytosine methylation in all contexts and maintains asymmetric CHH methylation. Mature plant embryos show one of the highest levels of CHH methylation, and it has been suggested that RdDM is responsible for this hypermethylation. |
