Identification of <i>Tobacco streak virus</i> Associated With a Virus-like Mottle Symptom on <i>Hosta</i>

Fig. 2. PCR detection of TSV from cDNAs synthesized from immunocaptured virions (Lanes 1, 2) and dsRNA template (Lanes 3, 4) with MP-specific primers (Lanes 1, 3) and CP-specific primers (Lanes 2, 4). Water controls with MP primers (Lane 5), CP primers (Lane 6), and Hosta virus X (HVX) triple gene block primers (TGB) (Lane 7). HVX TGB clone used as a positive PCR control with HVX TGB primers (Lane 8). M = 1 Kb DNA ladder (250, 500, 750, 1000, 1500, and 2000 bp markers indicated). Electrophoresis was done in 0.8% agarose at 100 volts for 90 min in 1X TAE buffer. Gel was stained with ethidium bromide. MP and CP amplicons are 1040 bp and 950 bp, respectively.
