Abstract excerpt

Female gametophyte development initiates from the megaspore mother cell (MMC), and only 1 somatic cell develops into an MMC. Here, we report that the balance between DNA methylation and demethylation ensures the maintenance of a single MMC in Arabidopsis (Arabidopsis thaliana). Surprisingly, a decrease or an increase of all 3 DNA methylation types (mCG, mCHG, and mCHH) caused abnormal enlargement of MMC-like...
