Relative expression (RE) of ShPDR1 and ShatrD in two insensitive Sclerotinia homoeocarpa isolates (HRI11 and HFI40) in the absence and presence of propiconazole (0.1, 1 and 5 μg/mL) for 1 h. All bars (grey, RE of ShPDR1; white, RE of ShatrD) represent mean RE values. Error bars indicate one standard error of the mean. Significant differences between RE values of ShPDR1 and ShatrD are indicated: n.s., not significant; ***, significant at P < 0.0001.
