Figure 1 (Left) Scheme showing the accessibility to antibodies of various parts of the coat protein amino acid (aa) sequence in particles of Beet necrotic yellow vein virus (BNYVV). Encircled numbers designate different epitopes. (Center) Negative contrast electron micrograph of stained purified particles of BNYVV. (Right) From left (a) negative contrast electron micrograph of a BNYVV particle and (b, c, d) computer-filtered micrographs of BNYVV particles. (Courtesy of A.C. Steven, from Virology 113, 428, 1981, with permission.) The bar represents 100 nm.
Figure 2 Genome organization and translation strategies of Beet necrotic yellow-vein virus (BNYVV). The scheme indicates a suppressible UAG stop codon (arrow), and (An) the 3 poly (A)-tails. Dark areas indicate conserved motifs. Hel; helicase, Mt; methyltransferase, RdRp; RNA dependent RNA polymerase, RT; readthrough.
