Expansion of the Host Range of <i>Impatiens necrotic spot virus</i> to Peppers

Fig. 4. RT-PCR analysis of total RNA extracted from pepper leaves of healthy plants (Lane 2) and those inoculated with INSV by thrips transmission (Lane 3). A DNA fragment of approximately 1.3 kilobase pairs (kpb) was amplified only from total RNA extracted from thrips-inoculated plants, which developed symptoms similar to those in Figs. 1 and 2. RT-PCR of total RNA extracted from E. sonchifolia [(L.) DC. Ex Wight] inoculated with sap prepared from INSV-infected or mock inoculated pepper plants are shown in Lanes 4 and 5, respectively. DNA molecular weight markers (1 kb ladder, Invitrogen, CA) are shown in Lane 1. The sizes (in kbp) of marker fragments are shown on the left.
