Endophytic fungus-induced volatile-oil accumulation is dependent on JA generation. Thirty-day-old plantlets of Atractylodes lancea were incubated with 5-mm mycelial disks or PDA disks (control). (A) Jasmonic acid production at 2-day intervals. Asterisks indicate significant differences from the control (0 d) (t-test; *, P <0.05; **, P <0.01). (B) Effects of JA inhibitors on endophytic fungus-induced volatile-oil accumulation after 18 d. Inhibitors (0.1 mmol L-1 IBU or NDGA) were added 1 d before fungal inoculation. Values are means of three independent experiments. Bars with different lower-case letters were significantly different (one-way ANOVA, Duncan’s multiple range test, P <0.05).
