Establishment of virus infection through local cell-to-cell and systemic movement. Nicotiana benthamianaplants were agro-infiltrated with GPF-tagged Turnip mosaic virus (TuMV-GFP) or empty vector. Pictures were taken under UV light. a Model showing virus movement to establish local and systemic infection. b N. benthamiana plants infiltrated with empty. c N. benthamiana plants infiltrated with TuMV-GFP and showing local infection. d After cell-to-cell movement, TuMV reaches the veins and vascular tissues (white arrowheads). e Establishment of systemic infection after long-distance movement through the vascular system
