P. parasitica infection of susceptible and resistant tobacco cultivars alongside transformed MIM159 lines. A to E, Leaves 3 d postinoculation with agar (Control) on one side and P. parasitica hyphae on the other are shown for susceptible tobacco NT90 (A), resistant tobacco NC2326 (B), MIM159 transgenic line L2 (C), MIM159 transgenic line L6 (D), and MIM159 transgenic line L12 (E). Scale bars = 10 mm. Asterisks in A–C indicate cell death associated with wounding or HR. F, Percentage of infection in leaves inoculated with P. parasitica or control V8 agar (n = 12–15).
