β-Glucuronidase pip promoter activity in X. oryzae pv. oryzae XKK.12(pPIP122) in the presence of a mixture of structurally different AHLs. PYS, rich PYS medium; Infected-Rice-Medium, rice which was infected with X. oryzae pv. oryzae for 10 days prior to maceration; PYS+AHLs, rich PYS medium containing 2 μM each of the 15 most structurally common AHLs; Infected Rice Medium+AHLs, rice which was infected with X. oryzae pv. oryzae for 10 days prior to maceration and contained 2 μM each of the 15 most structurally common AHLs (see the text for details). No pip promoter activation and no binding competition were observed in the presence of AHLs. The results are expressed as means ± standard deviations (n = 3). Statistical analysis revealed no statistically significant differences (P ≥ 0.05) between PYS and PYS+AHLs values or between Infected-Rice-Medium and Infected-Rice-Medium+AHLs values.
