+== Function ==
+[https://www.uniprot.org/uniprot/NRPD1_ARATH NRPD1_ARATH] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (By similarity). Largest and catalytic component of RNA polymerase IV which mediates 24-nt short-interfering RNAs (siRNA) accumulation. Implicated in siRNA-directed heterochromatin formation through the action of DCL3 and AGO4, and subsequent DNA methylation-dependent silencing of targeted sequences. Essential component of a self-reinforcing loop coupling de novo DNA methylation to siRNA production. Required for intercellular but not intracellular RNA interference (RNAi) leading to systemic post-transcriptional gene silencing. Involved in the maintenance of post-transcriptional RNA silencing.<ref>PMID:10850496</ref> <ref>PMID:12198169</ref> <ref>PMID:15692015</ref> <ref>PMID:15766525</ref> <ref>PMID:16140984</ref> <ref>PMID:16273107</ref> <ref>PMID:16377568</ref> <ref>PMID:16839878</ref> <ref>PMID:17360559</ref> <ref>PMID:17526749</ref> <ref>PMID:17558406</ref> <ref>PMID:17785412</ref> <ref>PMID:18287047</ref> <ref>PMID:18433438</ref> <ref>PMID:18467467</ref> <ref>PMID:19110459</ref>
