Effects of an Alphasatellite on the Life Cycle of the Nanovirus .

Nanoviruses are plant viruses with a multipartite single-stranded DNA (ssDNA) genome. Alphasatellites are commonly associated with nanovirus infections, but their putative impact on their helper viruses is unknown. In this study, we investigated the role of subterranean clover stunt alphasatellite 1 (here named SCSA 1) on various important traits of (FBNYV) in its host plant and aphid vector , including disease symptoms, viral accumulation, and viral transmission.
