To shed light on the role of some of the above-described interactors in the completion of the TuMV cycle, we inoculated wild-type plants and at1g30070, cnx1, npr1-1, obe1, pcap1, pip1;3, rp40, sce1, sumo3, and tga1-1 mutant plants with the same amount of TuMV inocula and tracked the progression of infection for 14 days post-inoculation in terms of percentage of plants displaying systemic infection and severity of the symptoms induced in the leaves (Fig. 7). This evidence concerns the gene SUMO3 and infection.
