Inductive genes upon aerial exposure to (+)-borneol in Arabidopsis

When aboveground parts of intact plants are exposed to volatile organic compounds emitted from neighboring con-/heterospecific plants that are artificially damaged or damaged by herbivores, the resistant responses are induced in the plants. Differential responses of plants to enantiomers of the same volatile compound have also been reported in Arabidopsis: the root became shorter when Arabidopsis seedlings are exposed to aerial borneol, and the dose-dependent root length reduction was significantly different between (+)- and (-)-borneol. We identified (+)-borneol dependent inductive genes in Arabidpsis in this transcriptome analysis. Expression profiling in Arabidopsis leaves treated by 25 mM (+) or (-) borneol for 24h was compared to mock control using single-color method with two or three biological replicates.
