Potyviruses (viruses in the genus , family ) constitute the largest group of known plant-infecting RNA viruses and include many agriculturally important viruses that cause devastating epidemics and significant yield losses in many crops worldwide. Several potyviruses are recognized as the most economically important viral pathogens. Therefore, potyviruses are more studied than other groups of plant viruses. In the past decade, a large amount of knowledge has been generated to better understand potyviruses and their infection process. In this review, we list the top 10 economically important potyviruses and present a brief profile of each. We highlight recent exciting findings on the novel genome expression strategy and the biological functions of potyviral proteins and discuss recent advances in molecular plant-potyvirus interactions, particularly regarding the coevolutionary arms race. Finally, we summarize current disease control strategies, with a focus on biotechnology-based genetic resistance, and point out future research directions.
马铃薯 Y 病毒属（ 科）病毒是已知的最大的侵染植物的 RNA 病毒组，包含许多在农业上很重要的病毒，它们在世界范围内的许多作物中引发破坏性的流行病害并导致重大的产量损失。有几种马铃薯 Y 病毒属病毒被认为是最重要的经济上的植物病毒病原体。因此，马铃薯 Y 病毒属病毒比其他植物病毒群受到更多的研究。在过去的十年中，产生了大量的知识来更好地了解马铃薯 Y 病毒属及其感染过程。在这篇综述中，我们列出了前 10 种具有重要经济意义的马铃薯 Y 病毒属病毒，并简要介绍了每一种病毒。我们重点介绍了关于新颖的基因组表达策略和马铃薯 Y 病毒属蛋白的生物学功能的最新令人兴奋的发现，并讨论了分子植物-马铃薯 Y 病毒属相互作用方面的最新进展，特别是关于共同进化的军备竞赛。最后，我们总结了当前的疾病控制策略，重点是基于生物技术的遗传抗性，并指出了未来的研究方向。
