Fig. 4From: Bradyrhizobium japonicum IRAT FA3 promotes salt tolerance through jasmonic acid priming in Arabidopsis thalianaB. japonicum influences jasmonate production in Arabidopsis. Arabidopsis seedlings were treated with B. japonicum (inoculated) or 10 mM MgSO4 (non-inoculated) for up to 6 h. (A) JA 151, (B) JA 133, (C) jasmonoyl-isoleucine (JA-Ile) and (D) JA precursor 12-oxophytodienoic acid (OPDA) levels were measured by liquid chromatography mass spectrometry (LCMS). Graphs show mean data ± standard error with asterisks representing significant differences from the corresponding non-inoculated control; Student’s t-test, p < 0.05Back to article page
