文摘

RNA-directed DNA methylation in plants involves siRNAs and long noncoding RNAs. Double-stranded RNA precursors of 24 nt siRNAs have recently been identified. Properties of long noncoding RNAs made by RNA Polymerase V remain enigmatic. Pol V transcripts have 5′ triphosphate groups and lack poly-A tails. Facts, missing information and controversies are reviewed.
