Potato, the world's most popular crop is reported to provide a food source for nearly a billion people. It is prone to a number of biotic stressors that affect yield and quality, out of which (PVY) occupies the top position. PVY can be transmitted mechanically and by sap-feeding aphid vectors. The application of insecticide causes an increase in the resistant vector population along with detrimental effects on the environment; genetic resistance and vector-virus control are the two core components for controlling the deadly PVY. Using transcriptomic tools together with differential gene expression and gene discovery, several loci and genes associated with PVY resistance have been widely identified. To combat this virus we must increase our understanding on the molecular response of the PVY-potato plant-aphid interaction and knowledge of genome organization, as well as the function of PVY encoded proteins, genetic diversity, the molecular aspects of PVY transmission by aphids, and transcriptome profiling of PVY infected potato cultivars. Techniques such as molecular and bioinformatics tools can identify and monitor virus transmission. Several studies have been conducted to understand the molecular basis of PVY resistance/susceptibility interactions and their impact on PVY epidemiology by studying the interrelationship between the virus, its vector, and the host plant. This review presents current knowledge of PVY transmission, epidemiology, genome organization, molecular to bioinformatics responses, and its effective management.
马铃薯是世界上最受欢迎的作物，据报道它为近十亿人提供食物来源。它容易受到多种影响产量和品质的生物胁迫因素的影响，其中马铃薯Y病毒（PVY）最为严重。PVY可通过机械传播以及由吸食汁液的蚜虫传播。施用杀虫剂会导致抗性蚜虫种群增加，同时对环境产生不利影响；基因抗性和媒介-病毒控制是控制致命PVY的两个核心要素。利用转录组学工具以及差异基因表达和基因发现，已经广泛鉴定出了几个与PVY抗性相关的基因座和基因。为了对抗这种病毒，我们必须加深对PVY-马铃薯植株-蚜虫相互作用的分子反应、基因组组织知识、PVY编码蛋白的功能、遗传多样性、蚜虫传播PVY的分子机制以及PVY感染马铃薯品种的转录组分析的理解。分子和生物信息学工具等技术可以识别和监测病毒传播。通过研究病毒、其媒介和寄主植物之间的相互关系，已经开展了多项研究来了解PVY抗性/易感性相互作用的分子基础及其对PVY流行病学的影响。本综述介绍了PVY传播、流行病学、基因组组织、分子到生物信息学反应以及有效管理的当前知识。
