Abstract
AbstractOcean viromes remain poorly understood and little is known about the ecological factors driving aquatic RNA virus evolution. In this study, we used a meta-transcriptomic approach to characterize the viromes of 58 marine invertebrate species across three seas. This revealed the presence of 315 newly identified RNA viruses in nine viral families or orders (Durnavirales, Totiviridae, Bunyavirales, Hantaviridae, Picornavirales, Flaviviridae, Hepelivirales, Solemoviridae and Tombusviridae), with most of them are sufficiently divergent to the documented viruses. With special notice that we first time revealed an ocean virus rooting to mammalian hantaviruses. We also found evidence for possible host sharing and switch events during virus evolution. In sum, we demonstrated the hidden diversity of marine invertebrate RNA viruses.
