There is usually more than one type of pathogen living in plants, which may include fungi and viruses. We know that in the process of plant-fungus interaction, there may be the exchange of biological macromolecules such as small RNA and secretory proteins. The paper led to a better understanding of how viruses, as large molecules, are transmitted between plants and fungi.
CMV can be parasitic in plants such as potatoes and tobacco, and can also be parasitic in Rhizoctonia solani. And these two hosts can exchange CMV viruses with each other. The presence of CMV makes Rhizoctonia solani more virulence and thus more seriously damage plants.
The ideas of this paper are as follows: virus was isolated from fungus, sequenced and then de novo assembled from clean reads, and CMV virus was identified through blast; Experimental verification of the existence of the virus; Whether the virus can infect other fungi; Viruses are transported from plants to fungi; Viruses are transported from fungi to plants.
