Identification of Cartilaginous Fish Endogenous Foamy Virus Rooting to Vertebrate Counterparts

Abstract

Although foamy viruses (FVs) have been found in major branches of vertebrates, the presence of these viruses in cartilaginous fish, the most basal living vertebrates with jaws, remains to be explored. This study revealed a collection of cartilaginous endogenous FVs in sharks and rays through in silico genomic mining.
