Representative TEM micrographs of leaf tissue from agroinoculated plants.
Filamentous flexuous virus-like particles are detected in leaf bundle sheath cells of agroinfiltrated N. benthamiana (A, B, C) and agrodrenched V. vinifera (D, E, F). In the bundle sheath cells, membrane-bound organelles (arrow) are observed in both N. benthamiana (B, C) and V. vinifera (D, E, F) agroinoculated plants. In agrodrenched V. vinifera, large globular vesicles and filamentous virus-like particles can be clearly detected inside the membrane-bound organelles (D, E, F, arrows). (BSC: bundle sheath cell, V: virus-like particles).
