Authentication of contigs 19, 29, and 12. Agarose gel (1.2%) electrophoresis of RT-PCR products from total RNA extracted from WMoV-infected wheat plants using two pairs of primers for each contig. Primers specific to RNA 3 were used as a positive control. Lane M, DNA 1.0-kbp ladder; lanes 1 and 2, total RNA from two WMoV-infected wheat plants; lane 3, RNA from healthy wheat; and lane 4, water control.
