FIG. 2.
Symptom modulation by the TCV subviral RNAs coinoculated with the helper TCV (A), TCV-CPCCFV (B), and TCV-CPm (C). Seedlings of A. thaliana ecotypes Col-0 and Di-0 at the six- to eight-leaf stage were inoculated with buffer alone (Mock), helper virus genomic RNA without any subviral RNA (None), or with satC (C), satC56G (C56G), satC∗ (C∗), diG (G), and diG56C (G56C), as indicated below the plants. Representative plants were photographed at 17 dpi. The helper virus used to inoculate the plant is shown on the right. Di-0 plants are resistant to infection by TCV. T/C, TCV-CPCCFV; CPm, TCV-CPm.
