LLP1 and Pip act downstream of volatile monoterpenes in pinene-induced resistance. a Setup of a pinene fumigation experiment. Plants were exposed to a mixture of α- and β-pinene (molar ratio 1:1; Pin) in air-tight glass containers or to the solvent hexane as the mock (M) control treatment. The plants were subsequently released from the containers and inoculated in the leaves with Pst. b In planta Pst titers at 4 dpi of pinene (Pin)- or mock (M)-treated plants. The plant genotypes are indicated below the panel and include ald1 with compromised Pip accumulation. Dots indicate individual results from three to four biologically independent experiments per genotype and treatment (including three replicates each). Bars represent the average of the indicated results ± standard deviation. Different letters above bars indicate significant differences, one-way ANOVA, P < 0.05
