Interactions between JA and NO or H 2 O 2 signaling pathways induced by endophytic fungus. Thirty-day-old plantlets of Atractylodes lancea were incubated with 5-mm mycelia disks with or without inhibitors and were harvested 18 d later for determination of JA and NO or H2O2 concentrations. (A) Interactions between JA and NO pathways. Inhibitors were 1.25 mmol L-1 cPTIO, 0.1 mmol L-1 IBU, or 15 mmol L-1 H2O2. (B) Interactions between JA and H2O2. Inhibitors were 3 mmol L-1 DPI, 5.25 mKat L-1 CAT, 0.1 mmol L-1 IBU, 1 mmol L-1 PAC, or 2.5 mmol L-1 AIP. All inhibitors were added 1 d before fungus 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).
