AtJMT-catalyzed MeJA formation depletes W + OS-induced JA levels. Mean (±sd, n = 5) constitutive and induced JA (A) and MeJA (B) levels (nmol g−1 FW−1) after mechanical wounding and application of M. sexta oral secretions to the puncture wounds (OS elicitation) in laminas of wild-type, 35S-jmt (35S-jmt-1, 35S-jmt-2), and 35S-jmt/ir-mje (35S-jmt/ir-mje-1, 35S-jmt/ir-mje-2) plants. Prior to elicitation, JA and MeJA levels in leaf laminas of 35S-jmt and 35S-jmt/ir-mje lines did not differ from those in wild type. The JA burst observed in wild-type leaf laminas after W + OS elicitation was largely absent in 35S-jmt and 35S-jmt/ir-mje plants but was mirrored, due to AtJMT activity, by a large burst of MeJA. Asterisks represent significant differences between wild-type and transgenic lines (unpaired t test; * P < 0.05, ** < 0.001, *** < 0.0001).
