Plants and microorganisms have been interacting in both positive and negative ways for millions of years. They are also frequently infected with viruses that can have positive or negative impacts. A majority of virus families with members that infect fungi have counterparts that infect plants, and in some cases the phylogenetic analyses of these virus families indicate transmission between the plant and fungal kingdoms. These similarities reflect the host relationships; fungi are evolutionarily more closely related to animals than to plants but share very few viral signatures with animal viruses. The details of several of these interactions are described, and the evolutionary implications of viral cross‐kingdom interactions and horizontal gene transfer are proposed.

数百万年来，植物和微生物通过正向和反向的方式互相作用。同时，植物还经常被病毒所侵染，这些病菌有些有正向、有些有负向的影响。大部分能够侵染真菌的病毒家族会存在对应能够侵染植物的病毒家族成员，在某些情况下这些病毒家族的进化分析揭示了植物与真菌之间的跨界传递。这些相似性反映了寄主之间的关系，相对于植物而言，真菌在演化上更加接近动物，但具有更少的与动物病毒相似的病毒特性。本文综述了这些互作的具体细节，包括病毒跨界互作和基因水平转移在演化上的意义。
