FIG. 2.

Locations of primers for RT-PCR on TSWV mRNAs containing 5′-terminal AMV sequences. Both the viral (v) and the viral complementary (vc) strands of the ambisense TSWV S RNA (4) are shown; open reading frames are indicated as hatched bars, and caps on AMV RNAs are indicated as black circles. An, primers for AMV RNAs 1 and 2 (A12), AMV RNA 3 (A3), or AMV RNA 4 (A4); N1, primer for RT reaction on TSWV N mRNA; N2, nested primer for PCR on TSWV N mRNA; NSs1, primer for RT reaction on TSWV NSs mRNA; NSs2, nested primer for PCR on TSWV NSs mRNA.
