N. benthamiana plants infected with PepMV vectors expressing GFP. a Fluorescence in N. benthamiana plants inoculated with PepGFP2a, PepGFPm1 or PepGFPm2 under UV light at 7 and 12 d post inoculation (dpi). b Agarose gel electrophoresis of RT-PCR products from individual plants to check insert stability in PepMV vectors at 7 and 12 dpi. A minimum of 6 plants were used per treatment, with each treatment replicated a minimum of 8 times. All infected plants showed systemic fluorescence at 7 dpi. IN: Inoculated leaves; SYS: Systemically infected leaves; PepMV-Sp13, wild type virus
