Fig. S1. Strategy for amplifying viral segments of 200 bp and joining the segments to generate 600 bp and 1000 bp tandem segments. (a) The six primers used for the PCR to generate the three 200 bp segments and the 600 bp tandem fusions. The internal primers contained 5 proximal sequences of a different virus complementary to the 3 proximal sequences of another primer for synthesis on the opposite strand. This is to produce the overlapping sequences necessary to facilitate joining of the 200 bp PCR products to form various fusions. (b) The ten primers used for the PCR to generate the five 200 bp segments and the 1000 bp tandem fusions, with internal primers containing overlapping ends as for (a). (c) Summary of the primers used to generate each 200 bp segment for generating the 600 bp tandem fusions or the 1000 bp tandem fusions. (d) Summary of the steps and PCR reactions involving the numbered primers to generate intermediate tandem fusions and final 600 bp and 1000 bp tandem fusions.

Analysis of transgenic lines for expression of siRNAs against PVY and resistance to PVY-O as determined by visual symptoms and western blots for the presence of PVY-O CP. The gels above each blot show the loading controls for small RNAs. The numbers above the gel lanes refer to individual transgenic plants identified in the plant photos. The sizes and positions of protein molecular weight markers is shown on the left of each western blot. T2-generation transgenic plants were from lines 600-3-OUT-B2 (a), 600-3-OUT-C1 (b), 600-3-OUT-E1 (c), 1001-1- 2-OUT-A1 (d), and 1000-1-2-OUT-B1 (e).
