The nanovirus U2 protein suppresses RNA silencing via three conserved cysteine residues
Molecular Plant Pathology, Volume 25, Issue 1, January 2024.The nanovirus U2 protein was identified as the suppressor of RNA silencing. Three cysteine residues were critical to its nuclear localization, self‐interaction and siRNA‐binding ability, and were essential for its VSR activity. Abstract Nanoviruses have multipartite, circular, single‐stranded DNA genomes and cause huge production losses in legumes and ...
