  "summary": "Cytosine DNA methylation established by RNA-directed DNA methylation (RdDM) is critical for transposon silencing and genome integrity in plants. In reproductive tissues, RNA Polymerase IV (Pol IV) is recruited to specific genomic loci by DNA motifs and the transcription factor-GDE1-CLSY3/4 complex to initiate abundant siRNA biogenesis and de novo DNA methylation, but the mechanisms that stabilize…",
