Agroinoculation of Micro-Tom. a Schematic diagram of the construct pBI-TYLCV(1.5). The grey box indicates partial tandem copies of the TYLCV genome. The numbers above the boxes indicate their location (in nt) in the TYLCV genome. The two closed triangles indicate stem-loop regions of TYLCV. RB, a T-DNA right border and LB, a T-DNA left border. b Axillary bud (shown within a white dotted frame) emerging after injection of agroinoculum harboring partial tandem copies of TYLCV genome into a tenth branch of Micro-tom. Typical symptoms of TYLCV were observed in the bud. The white arrow indicates the location of the injection. c Comparison of the leaf (right) from the infected axillary bud with a corresponding leaf (left) from a noninfected healthy control
