Abstract

AbstractThe global virome is still largely unknown. In this study we describe the discovery of a newBetaflexivirusspecies inFerraria crispaplants. The plant samples were collected in an experiment of 25Asparagalesplants, obtained from an urban botanic garden in the Netherlands, and analyzed by smallRNA-seq as well as RNA-seq. The newBetaflexivirusonly occurred in fourFerraria cripsaplants and was tentatively named Ferraria Betaflexivirus 1 (FerBfV-1). ThisBetaflexivirusshowed an RNA genome structure characteristic for the genusCapillovirus, a single-stranded (+) RNA virus. The closest knownCapillovirusesin GenBank showed a protein similarity less than 49%, which is well below the proposed demarcation value of species in this genus. Further comparison analysis of theCapillovirusgenus revealed the possible presence of two groups.
