Research Abstract |
RNA silencing is an anti-virus defense mechanism in plants. On the other hands, many plant viruses have RNA silencing suppressor(RSS) gene(s) to counteract RNA silencing-mediated anti-viral defense. In this study, I showed that(1) Arabidopsis DCL2, DCL4, RDR1, and RDR6 were important for the anti-viral defense through,(2) siRNA molecules moved from cell to cell and a viral RSS interfered the siRNA movement, and(3) Red clover necrotic mosaic virus(RCNMV) P27 interacted with P88 and this interaction was important for the RCNMV RSS activity.
