Consider the following statements regarding RNA-based antiviral defence mechanisms in plants:
1. Spray-Induced Gene Silencing (SIGS) involves the external application of RNA molecules to plants without altering their DNA.
2. Host-Induced Gene Silencing (HIGS) is cost-effective and easily deployable as it does not involve genetic modification.
3. In RNA silencing, double-stranded RNA (dsRNA) triggers the plant’s immune system to destroy the viral RNA, preventing virus replication.
