Pol V lncRNAs or the act of their transcription primarily mediate the association of Pol V to chromatin. (A) Amino acid sequences of the catalytic sites (metal A) of different polymerase subunits from Arabidopsis thaliana, Saccharomyces cerevisiae, and Escherichia coli. (B) qRT–PCR analysis of Pol V lncRNA levels in Col-0 and nrpe1-11 and nrpe1-3 mutants. (Rel. Tran. Lev.) Relative transcript level. Values represent the means ± SD of three independent experiments. (C) ChIP analysis of Pol V binding in nrpe1-11 and nrpe1-3 mutants at different RdDM targets, as indicated at the right. Actin2 and Actin7 were used as controls. Values are means ± SD of two independent amplifications. After formaldehyde cross-link, Pol V complexes were immunoprecipitated using either the anti-NRPE5 or anti-NRPE1 antibody.
