Small RNAs and Their Roles in Plant Development (2009, background): “…A uthor M anuscript A uthor M anuscript A uthor M anuscript Biogenesis The production of heterochromatic siRNAs requires a specialized polymerase, Pol IV, and a potential chromatin remodeling protein, CLASSY1 (Herr et al. 2005, Kanno et al. 2005, Onodera et al. 2005, Smith et al. 2007) (Figure 4).”
The General Transcription Machinery and General Cofactors (2006, background): “…plants to facilitate the production of small interfering RNA (siRNA) involved in RNA-directed DNA methylation and transcriptional silencing and formation of heterochromatin, is also present in the nucleus and is resistant to α-amanitin (Herr et al., 2005; Kanno et al., 2005; Onodera et al., 2005).”
Micro RNAs and Short‐interfering RNAs in Plants (2007, background): “Selective disruption of nrpd1a or nrpd1b indicated that efficient silencing at transposons and highly repeated sequences requires the concerted action of both PolIV forms, while a basal level of silencing at low repetitive DNA is only dependent on NRPD1a (Herr et al. 2005; Onodera et al. 2005; Ponti”
Endogenous siRNAs Derived from a Pair of Natural cis-Antisense Transcripts Regulate Salt Tolerance in Arabidopsis (2005, neutral): “retroelements and transposons, 5S ribosomal RNA genes, endogenous direct and inverted repeats, and transgenes containing direct repeats (Chan et al., 2004; Xie et al., 2004; Zilberman et al., 2004; Herr et al., 2005; Onodera et al., 2005).”

Noncoding transcription by RNA Polymerase Pol IVb/Pol V mediates transcriptional silencing of overlapping and adjacent genes (2008, neutral): “Pol IVa/Pol IV and Pol IVb/Pol V have distinct largest subunits that have been named either NRPD1a and NRPD1b (Herr et al., 2005; Onodera et al., 2005 ) or RPD1 and RPE1 (Luo and Hall, 2007).”
DNA methylation mediated by a microRNA pathway. (2010, background): “In the RdDM pathway, transcripts from transposons and other repetitive elements are produced presumably by Pol IV, a plant-specific DNA-dependent RNA polymerase (Herr et al., 2005; Kanno et al., 2005; Onodera et al., 2005).”
