RNA silencing is an evolutionarily conserved system that
functions as an antiviral mechanism in higher plants and
insects. To counteract RNA silencing, viruses express
silencing suppressors that interfere with both siRNA- and
microRNA-guided silencing pathways. We used comparative
in vitro and in vivo approaches to analyse the molecular
mechanism of...
