Abstract

In addition to RNA polymerases I, II and III, which are multi-subunit RNA polymerases found in all eukaryotes, plants have catalytic subunits for two additional nuclear RNA polymerases, abbreviated as Pol IV and Pol V (formerly Pol IVa and Pol IVb, respectively). Pol IV and Pol V play non-redundant roles in siRNA-directed DNA methylation and gene silencing pathways.
