An asymmetric bulge enhances artificial micro RNA ‐mediated virus resistance

RNA silencing is a host defence mechanism against viruses in plants (Ding and Voinnet, 2007). As a counter defence mechanism, viruses have adapted ways to overcome the host RNA silencing pathway, such as viral suppressors of RNA silencing (VSR) (Incarbone and Dunoyer, 2013). Artificial miRNAs (amiRNAs) have been widely used as antiviral agents in plants as reported by Carbonell et al. (2019); Khalid et al. (2017); and Kis et al. (2016). However,...
