Transitivity in Arabidopsis can be primed, requires the redundant action of the antiviral Dicer-like 4 and Dicer-like 2, and is compromised by viral-encoded suppressor proteins. RNA. 2007;13:1268-78 pubmed..Finally, we show that target cleavage by a primary small RNA and 3-->5' transitivity can be genetically uncoupled, and we provide in vivo evidence supporting a key role for priming in this specific reaction. ..

The 20S proteasome ?5 subunit of Arabidopsis thaliana carries an RNase activity and interacts in planta with the lettuce mosaic potyvirus HcPro protein. Mol Plant Pathol. 2011;12:137-50 pubmed publisher..Taken together, these results extend to A. thaliana ?(5) the range of HcPro-interacting proteasomal subunits, and suggest that HcPro may modulate its associated RNase activity which may contribute to an antiviral response. ..
