Pathway toward gene silencing described in plants
...gs started, churning out RNA that then goes to the
nucleolus where it is acted on by RDR2, which turns the single-stranded RNA into double-stranded RNA. The Dicer-like 3 protein, DCL3 then chops the RNA into small interfering RNAs (siRNAs). Along comes ARGONAUTE4 (AGO4), which grabs hold of the siRNAs while ...
