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

Genome biology - 6 May 2021

Chakraborty Tania, Kendall Timmy, Grover Jeffrey W, Mosher Rebecca A

Abstract excerpt

BACKGROUND: 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. Because loss of RdDM in Brassica rapa causes seed abortion, embryo methylation might play a role in seed development. RdDM is...
