(a) Diagrammatic representation of AV2 full-length and N-terminal mutant gene fragments in the pGR106 vector. (b) Amino acid alignment of the full-length (AV2) and N-terminal-mutated (AV2Δ10N) proteins, depicting the deletion of 10 amino acids. (c) Symptomatic plants inoculated with PVX, PVX-AV2 and PVX-AV2Δ10N at 8 and 14 dpi, respectively, showing the necrotic lesions in PVX-AV2 infiltrated plants.
