In plants, selfish genetic elements, including retrotransposons and DNA viruses, are transcriptionally silenced by RNA-directed DNA methylation. Guiding the process are short interfering RNAs (siRNAs) cut by DICER-LIKE 3 (DCL3) from double-stranded p

Large regions of nearly identical repeats, such as the 45S ribosomal RNA (rRNA) genes of Nucleolus Organizer Regions (NORs), can account for major gaps in sequenced genomes. To assemble these regions, ultra-long sequencing reads that span multiple re

RNA-directed DNA methylation in plants is guided by 24 nt siRNAs generated in parallel with 23 nt RNAs of unknown function. We show that 23 nt RNAs function as passenger strands during 24 nt siRNA incorporation into AGO4. The 23 nt RNAs are then slic

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 larg

The expression of information encoded in genomes is not error-free. Transcript-error rates are dramatically higher than DNA-level mutation rates, and despite their transient nature, the steady-state load of such errors imposes a burden on cellular pe

The nucleolus is the site of rRNA gene transcription, rRNA processing, and ribosome biogenesis. However, the nucleolus also plays additional roles in the cell. We isolated nucleoli using fluorescence-activated cell sorting (FACS) and identified nucle

In eukaryotes, hundreds of ribosomal RNA (rRNA) genes are clustered at chromosomal loci called nucleolus organizer regions (NORs).Arabidopsis thalianahas two NORs, one on chromosome 2 (NOR2) and the other on chromosome 4 (NOR4). Each NOR consists of

Summary: Unlike nuclear multisubunit RNA polymerases I, II, and III, whose subunit compositions are conserved throughout eukaryotes, plant RNA polymerases IV and V are nonessential, Pol II-related enzymes whose subunit compositions are still evolving
