Abstract
Outbreaks of potato virus Y (PVY) have a serious negative impact on agricultural production, leading to significant losses. The need for an effective PVY control technique is essential to reduce yield losses in agriculture. Plants use a defense mechanism called RNA silencing, which was used to control PVY. Post-transcriptional gene silencing (PTGS) of major viral genes was induced by specific siRNAs that trig¬ger specific degradation of viral RNA by forming a multi-component RNA-induced silencing complex (RISC). By using PTGS, resistance of potato varieties to PVY was achieved.
