First Report of <i>Wisteria vein mosaic virus</i> in <i>Wisteria sinensis</i> in the United States of America

Fig. 2. RT-PCR analysis of total RNA extracted from WVMV-infected leaves ofW. sinensis (lane 1) and N. benthamiana (lanes 2 and 3). A single DNA fragment of approximately 1 kilobase pairs (shown by arrow on the right side) was amplified only from total RNA extracted from infected leaves and not healthy leaves (lane 4). Size of DNA molecular weight markers (lane Mr) are shown on the left side.
