RNA interference (RNAi)‐mediated SsFkh1 silencing compromised the pathogenicity of Sclerotinia sclerotiorum. (A) RNAi mutants and wild‐type (WT) strains were inoculated on detached 45‐day‐old tomato leaves and placed in a high‐humidity growth chamber. Photographs were taken 6 days after inoculation. (B, C) Diameters of infectious necrotic lesions were measured from (A). Each data point represents the mean ± standard deviation (SD) from three biological repeats (n = 3). Asterisks indicate significant difference compared with the WT strain [**P < 0.01, one‐way analysis of variance (ANOVA) in SPSS].
