中文摘要：

马铃薯Y病毒属（Potyvirus）是包含范围广、增殖过程复杂但基因组简单的一类重要病毒,对农业生产造成重大的经济损失。笔者介绍了马铃薯Y病毒属病毒的细胞生物学研究进展,并对potyviruses的复制模型、运动方式和途径等作了相关总结。

英文摘要：

Potyvirus,family Potyviridae,is the largest genus of plant virus,causing significant losses in a broad range of host plants.In recent years,researchers have contributed to the new advances of cell biology,so in this article the molecular biology involved in genome amplification,cell-to-cell and long-distance movement,symptom during potyviruses systemic infection were referred.
