<RNA polymerase V> is a <plant> nuclear <RNA polymerase> involved in <RNA-directed DNA methylation>. It produces noncoding transcripts that help recruit silencing machinery to selected genomic regions. Its role differs from <RNA polymerase IV>, which contributes to the small-RNA-generating arm of the pathway. These specialized polymerases connect <transcription> to repression, illustrating that making <RNA> need not imply productive expression of a protein-coding <gene>. <Noncoding transcription by RNA polymerase Pol IVb Pol V mediates transcriptional silencing of overlapping and adjacent genes by Andrzej T. Wierzbicki and others>[2008, Pol V transcription and silencing]{ref}
