Silencing of BnRALF10 reduced resistance to S. sclerotiorum in oilseed rape. (A) Photobleaching phenotype of BnPDS silencing in oilseed rape employing pTY-based VIGS. Empty vector pTY-S was used as a control. (B) Efficient silencing of BnRALF10 in leaves as manifested by the dramatically reduced level of BnRALF10 transcript, which was detected by qRT-PCR analysis using B. napus actin (BnActin7) as reference gene. (C) Representative disease symptoms (left), lesion areas (middle) and fungal biomass (right) of BnRALF10-silenced leaves at 24 h post inoculation with S. sclerotiorum. Scale bar: 1 cm. Data are statistically analyzed by Student’s t-test (n = 10) and shown as the mean ± SE. The asterisks indicate significant differences (*P ≤ 0.05, ***P ≤ 0.001, ****P ≤ 0.0001).
