植物病毒已经进化出一系列广泛的策略，以确保从一个宿主有效转移到下一个宿主。任何以受感染植物为食并在植物之间传播的生物体都可能充当病毒传播装置。这种被称为载体的生物体存在于寄生真菌、根线虫和以植物为食的节肢动物，特别是昆虫中。由于蚜虫极其特殊的取食行为（探索并采样从表皮到韧皮部和木质部的所有植物组织），蚜虫是迄今为止最重要的媒介，传播迄今为止描述的所有植物病毒种类的近 30%。病毒和蚜虫媒介之间已经进化出几种不同的相互作用模式，并且在过去的一个世纪中，大量研究提供了潜在机制的详细信息。本文概述了不同类型的病毒-蚜虫关系、这些相互作用背后的分子过程的最新知识，以及在不久的将来等待打开的剩余黑匣子。 (C) 2010 年科学院。由 Elsevier Masson SAS 出版。版权所有。
Plant viruses have evolved a wide array of strategies to ensure efficient transfer from one host to the next. Any organism feeding on infected plants and traveling between plants can potentially act as a virus transport device. Such organisms, designated vectors, are found among parasitic fungi, root nematodes and plant-feeding arthropods, particularly insects. Due to their extremely specialized feeding behavior - exploring and sampling all plant tissues, from the epidermis to the phloem and xylem - aphids are by far the most important vectors, transmitting nearly 30% of all plant virus species described to date. Several different interaction patterns have evolved between viruses and aphid vectors and, over the past century, a tremendous number of studies have provided details of the underlying mechanisms. This article presents an overview of the different types of virus-aphid relationships, state-of-the-art knowledge of the molecular processes underlying these interactions, and the remaining black boxes waiting to be opened in the near future.
