The 21-Nucleotide, but Not 22-Nucleotide, Viral Secondary Small Interfering RNAs Direct Potent Antiviral Defense by Two Cooperative Argonautes in Arabidopsis thaliana[W][OA]
This work identifies cooperative action of ARGONAUTE1 and ARGONAUTE2 in virus resistance conferred by 21-nucleotide virus-derived small interfering RNAs (siRNAs). It also reveals that 22-nucleotide viral siRNAs do not guide efficient antiviral defense, demonstrating a qualitative difference between 21- and 22-nucleotide classes of siRNAs in RNA silencing
