OS-induced accumulation of oxylipin derivatives in S. vermifera-inoculated and uninoculated N. attenuata plants. Mean ± se JA concentrations in leaves of uninoculated (white symbols) and S. vermifera inoculated (black symbols) wild-type plants. Fully mature leaves (at nodal position +1) of rosette-stage plants were OS elicited and harvested from 15 to 90 min after inoculation. Untreated leaves were harvested at time 0 min. Inset: Mean + se, JA Ile + JA Leu (JA-Ile/Leu) concentrations in leaves of uninoculated (white bars) and S. vermifera-inoculated (black bars) wild-type N. attenuata. OS-induced samples were harvested 35 min after wounding and OS application to the leaves; control samples were taken from leaves at the same nodal position of nonelicited plants.
