Oxylipin-Containing Polar Lipid Species in 3-d LT-Treated Col and vte2 Petioles.
Compounds containing 18-carbon oxygenated fatty acyl anions were analyzed by mass spectrometry as described in Methods. White- and black-dotted bars are Col and vte2 petioles, respectively, after 3 d of LT treatment. Data include 34 molecular species (9 PC, 10 PE, 3 PG, 7 MGDG, and 5 DGDG) with oxygenated 18-carbon fatty acids; details about the analyzed species are given in Supplemental Figure 1 online. Values are means ± sd (n = 5 biological replicates). No significant differences were observed in all cases between genotypes (Student's t test, P > 0.05).
