Figure 4.
Expression of dsRNA of VdAK improved Vd resistance in N. benthamiana compared to wild-type plants (WT). WT and trans-VdAK plants were inoculated with wild-type Vd (Vd wt). (A) Symptoms on transgenic and wild-type plants at 12 days after roots were dipped in 106 spores/mL of the respective strains. (B) Relative amounts of fungal DNA as determined by RT-qPCR. (C) Transcript levels of VdAK in stems of transgenic and WT plants. Means (± SE) from three independent experiments that differed significantly among treatments in Duncan’s test (p <0.05) are indicated by different letters.
