  abstract = {{D}-pinitol is an effective agent for controlling powdery mildew ({P}odosphaera xanthii) in cucumber. {I}n this study, we determined the mechanisms of {D}-pinitol in controlling powdery mildew in cucumber plants. {W}e compared {P}. xanthii development on cucumber leaf surface treated with {D}-pinitol or water (2 mg ml(-1)) at different time points after inoculation. {T}he germinating conidia, hyphae, and conidiophores of the pathogen were severely damaged by {D}-pinitol at any time of application tested. {T}he highest level of suppression of fungal development was obtained at 3 days after inoculation. {T}he contents of chlorophyll, total phenolics, flavonoid, and gallic acid and its derivatives ({GAD}); the activities of phenylalanine ammonialyase ({PAL}), polyphenoloxidase ({PPO}), peroxidase ({POX}), and superoxide dismutase ({SOD}); and the expression of the genes encoding for {PR}-1, peroxidase ({POX}), lipoxygenase ({LOX}1), chitinase ({C}hit1) were higher in the cucumber leaves treated with {D}-pinitol and inoculated than in the leaves either treated with {D}-pinitol or inoculated with the pathogen. {T}hese results suggest that {D}-pinitol triggers several plant defense responses in cucumber leading to pathogen suppression and resistance to powdery mildew.},
