Plant multisubunit RNA polymerase V (Pol V) transcription recruits Argonaute-small interfering RNA (siRNA) complexes that specify sites of RNA-directed DNA methylation (RdDM) for gene silencing. Pol V's largest subunit, NRPE1, evolved from the largest subunit of Pol II but has a distinctive C-terminal domain (CTD). We show that the Pol V CTD is dispensable for catalytic activity in vitro yet essential in vivo. One CTD subdomain (DeCL) is required for Pol V function at virtually all loci. Other C ...[more]
