Complementary interaction between JA and SA signaling pathways induced by endophytic fungus. Thirty-day-old plantlets of Atractylodes lancea were incubated with 5-mm mycelia disks and 0.1, 1, or 3 mmol L^-1 IBU; 3 mmol L^-1 DPI; or 0.1, 1, or 2.5 mmol L^-1 AIP and 3 mmol L^-1 PAC. Plants were harvested 18 d later to determine JA and volatile oil levels. Inhibitors were added 1 d before fungus inoculation. (A) Interactions between JA and SA pathways. (B) Volatile oil production. 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).
