Abstract: The different shape mushroom viruses are part of mycoviruses and most of them possess undivided dsRNA genomes, but some of them possess the positive single-strand genomes. The undivided dsRNA genomes composed of a coat protein (CP) gene and an RNA dependent RNA polymerase (RdRp) gene are the best feature of genomes of mushroom viruses. Mushroom viruses have been sequenced and the structure and function of their genomes have been analyzed. DsRNA technique and the method of enzymology make the study of the mushroom viruses easy to reach to molecular level. Especially dsRNA technique applied to the Pleurotus ostreatus. Mushroom viruses have special replicative form, which have two phases, and the theory of a cellular self-replicating mRNA as their origin of them is attractive because of their obvious ancient origin. These contents were reviewed in this paper. We expatiate on the further research progress in the relationship between mushroom viruses and their hosts. It is important to research further the mushroom viruses and to screen the free viruses strain.
