FIGURE 5.

Comparison of pathogenicity between F. oxysporum strain B9-VI (virus infect) and B9 (virus-free) on the tobacco cultivar ‘Zhongyan 100’ and N. benthamiana. (A) Strain B9-VI and B9 inoculated tobacco cultivar ‘Zhongyan 100’ were grown in pots for 31 days (left), and comparison of growth status of plants inoculated with strain B9-VI and B9 (right). (B) Strain B9-VI and B9 inoculated tobacco cultivar N. benthamiana were grown in pots for 31 days (left), and comparison of growth status of plants inoculated with strain B9-VI and B9 (right). (C,D) Average plant height, root length, and fresh weight of two tobacco cultivars inoculated with strain B9-VI and B9. Strain B9-VI infects by FoMyV1, strain B9 is the mycovirus-free. The “control” in panels (C,D) represents plants that have not been inoculated with any pathogens.
