Sensing and regulation of genomic DNA methylation [Plant Biology]

De novo DNA methylation through the #RNA-directed DNA methylation (RdDM) pathway and active DNA demethylation play important roles in controlling genome-wide DNA methylation patterns in plants. Little is known about how cells manage the balance between DNA methylation and active demethylation activities. Here, we report the identification of a unique… http://bit.ly/1Gd0RUA #PNAS
