Potyviruses are the largest group of plant virus pathogens, which are constantly expanding their territories of emergence, threatening their hosts worldwide. Potato virus Y(PVY) epidemics have a serious negative impact on agricultural productivity, resulting in significant losses to farmers. The need of efficient technique to control PVY is essential for decreasing yield loss in agriculture. Plants employ a defense mechanism called RNA silencing, which we used to direct against the Potyviruses. We induced posttranscriptional gene silencing (PTGS) of essential multifunctional virus gene, such as HC-Pro by specific siRNAs which promote sequence-specific viral RNA degradation by forming a multicomponent RNA-induced silencing complex (RISC). By using PTGS against HC-Pro, we achieved potato resistance to PVY.
