摘要

Nanoviruses are multi-component plant-infecting single-stranded DNA viruses. Using a viral metagenomics-informed approach, a new nanovirus and two associated alphasatellite molecules have been identified in an uncultivated asymptomatic Vicia cracca plant in the Rhne region of France. This novel nanovirus genome includes eight genomic components (named DNA-R, DNA-S, DNA-M, DNA-C, DNA-N, DNA-U1, DNA-U2 and DNA-U4) and, across all components, shares < 66% pairwise sequence identity with other nanovirus genomes. The two associated alphasatellites share 62% identity with each other and < 81% identity will all other nanovirus-associated alphasatellites.
