Fig. 4: Profiling of plant VOCs from an emitter plant treated with PGPR.
From: Achieving similar root microbiota composition in neighbouring plants through airborne signalling
a VOCs released aboveground by emitter plants collected via polydimethylsiloxane (PDMS) tubing pieces. b Schematic of a TD–GC–MS system for plant volatile analysis. c Three eSPB-specific volatiles selected on the basis of peak area (normalized relative to the PDMS derived peak). d Total ion chromatograms of VOCs released by emitter plants. The experiment was performed in triplicate. Significant differences were determined by one-way analysis of variance (ANOVA), followed by Tukey´s honestly significant difference (HSD) test, and are indicated by asterisks (*P < 0.05, **P < 0.01, ***P < 0.001).
