Figure 7.

Back‐inoculations of Nicotiana benthamiana plants using sap from TuMV‐GFP (green fluorescent protein‐expressing Turnip mosaic virus clone)‐inoculated Arabidopsis. Sap was prepared by pooling 20 systemic leaves from TuMV‐GFP‐inoculated Arabidopsis plants as shown in Fig. S3. Labels above each quadrant refer to the genotype [wild‐type (WT), #44, #65, #68, #98 and transposon (Tn)] of the inoculated Arabidopsis used to make sap. Each quadrant shows an inoculated leaf (I) and systemic tissue (S) for two replicate plants imaged under UV light. A 1‐cm scale bar is shown for each image.
