Treatment dependent elicitation of 9- and 13- cylcopentenones in leaf and node/internode tissue. (A) Average (n = 4, ± SEM) concentrations (µg g−1 FW) of 10-OPEA (black), 10-OPDA (light gray) and 12-OPDA (dark gray) in maize interior whorl and node/internode tissue 1, 2, and 3 d following SLB inoculation. (Insert) Average (n = 3, ± SEM) concentrations (µg g−1 FW) of 10-OPEA, 10-OPDA and 12-OPDA in fully expanded maize leaves in response to no treatment (NT), damage (DAM), and fall armyworm regurgitant (FAW-R) 1 hour post-application. The limits of detection for 10-OPEA, 10-OPDA, and 12-OPDA are at 10pg/µl (All ANOVA P< 0.05, Tukey test corrections for multiple comparisons).
