Volatile 3-pentanol-mediated induced resistance in Arabidopsis mutants against Pto. Arabidopsis Col-0 seedlings (A), etr1-3 (B), jar1-1 (C), npr1 (D), NahG (E), and sid2 (F) were exposed to 100 nM and 10 μM 3-pentanol evaporate or sterile distilled water control. After 5 days, all plants were drop-inoculated with Pto. Disease severity was measured 7 days after pathogen inoculation. Numbers represent means of 12 replications per treatment, with one seedling per replication. Different letters in (A) to (F) indicate significant differences between treatments (P = 0.05 by LSD). Error bars represent means ± SEM. (G) Plants were photographed 7 days after pathogen challenge.
