Oysters from five continents harbour a vast array of previously unknown RNA viruses, including many putative viruses of vertebrates
Oysters are vital to global aquaculture and marine ecosystems, yet, their associated RNA viruses remain largely unexplored. Here, we analysed ∼1,000 publicly available metatranscriptomic datasets from 13 oyster species across 14 countries and 5 continents to characterize the oyster RNA virome (ORV). We identified 1,515...
