A mutation in a xenobiotic detoxification regulator 1 (ShXDR1) is a dominant gain-of-function mutation leading to multidrug resistance by constitutive and induced overexpression of phase I and III genes. (A) Sensitivity of strains HRS10, HRI11, and HRS10(+ShXDR1^T853)-1 and -2 to fungicides and plant growth regulator. (B) Relative expression (RE) of phase I and III genes before and after exposure to propiconazole (1 µg ml⁻¹) for 40 min in strains HRS10, HRI11, and HRS10(+ShXDR1^T853)-1 and -2.
