Subunit Compositions of the RNA-Silencing Enzymes PoI IV and PoI V Reveal Their Origins as Specialized Forms of RNA Polymerase II

In addition to RNA polymerases I, II, and III, the essential RNA polymerases present in all eukaryotes, plants have two additional nuclear RNA polymerases, abbreviated as Pol IV and Pol V, that play nonredundant roles in siRNA-directed DNA methylation and gene silencing. We show that Arabidopsis Pol...
