Subjects

Plants defend themselves from invading viruses using RNA silencing. However, plant viruses try to spoil this defensive mechanism by expressing one or more proteins that act as RNA silencing suppressors. One such protein spoils plant defence by transporting the silencing signal into the peroxisomes to avoid its systemic spread.
