Most plant viruses are absolutely dependent on a vector for plant-to-plant spread. Although a number of different types of organisms are vectors for different plant viruses, phloem-feeding Hemipterans are the most common and transmit the great majority of plant viruses. The complex and specific interactions between Hemipteran vectors and the viruses they transmit have been studied intensely, and two general strategies, the capsid and helper strategies, are recognized. Both strategies are found for plant viruses that are transmitted by aphids in a nonpersistent manner. Evidence suggests that these strategies are found also for viruses transmitted in a semipersistent manner. Recent applications of molecular and cell biology techniques have helped to elucidate the mechanisms underlying the vector transmission of several plant viruses. This review examines the fundamental contributions and recent developments in this area.

病毒-载体相互作用介导植物病毒的非持久和半持久传播。

大多数植物病毒绝对依赖载体在植物间传播。尽管许多不同类型的生物体是不同植物病毒的载体，但进食韧皮部的半足动物是最常见的，并传播绝大多数植物病毒。Hemipteran载体与它们传播的病毒之间复杂而特殊的相互作用已经得到了深入的研究，人们认识到衣壳和辅助策略这两种通用策略。两种策略都针对由蚜虫以非持久方式传播的植物病毒找到。有证据表明，对于以半持久方式传播的病毒也发现了这些策略。分子和细胞生物学技术的最新应用已帮助阐明了几种植物病毒载体传播的基础机制。
