共生是一种常见的现象，在这种现象中，相关的生物体可以通过合作来提高它们生存、繁殖或利用恶劣环境的能力。本文讨论寄生蜂的多dna病毒共生体。这些病毒在两个方面是新颖的：(1)它们已经成为非自主的驯化实体，不能在黄蜂之外复制；(2)它们作为基因的传递载体，确保被寄生蜂寄生的寄主昆虫成功寄生。在这篇综述中，我们讨论了这些新奇事物是如何产生的，哪些基因可能参与其中，以及对基因组进化的影响。
Symbiosis is a common phenomenon in which associated organisms can cooperate in ways that increase their ability to survive, reproduce, or utilize hostile environments. Here, we discuss polydnavirus symbionts of parasitic wasps. These viruses are novel in two ways: (1) they have become non-autonomous domesticated entities that cannot replicate outside of wasps; and (2) they function as a delivery vector of genes that ensure successful parasitism of host insects that wasps parasitize. In this review we discuss how these novelties may have arisen, which genes are potentially involved, and what the consequences have been for genome evolution.
