Abstract excerpt

Tomato aspermy virus (TAV) and cucumber mosaic virus (CMV) belong to the genus Cucumovirus in the family Bromoviridae. The cucumovirus 2b protein is one of the first identified viral suppressors of RNA silencing (VSR). The cucumovirus 2b protein contains a conserved amino acid motif consisting of several highly conserved amino acid residues. Here, we demonstrate that the TAV 2b protein N-terminal region, Arg46,...
