Summary of oxidized glycerolipids (nmol) in the stems of both soybean cultivars. Data represented are means ± standard errors for four sample replicates. Means in the same row accompanied by different superscripts represent significance differences (*) between the treatments, consisting of susceptible stem control (OSC) and susceptible stem inoculated (OSI); and tolerant stem control (CSC) and tolerant stem inoculated (CSI) from 10-day old plants, at a significance level assessed at α < 0.05. The oxylipins detected were oxidized phosphatidylcholine (Ox-PC), oxidized phosphatidylethanolamine (Ox-PE), oxidized phosphatidic acid (Ox-PA), and oxidized triacylglycerol (Ox-TG), O = monoxide, 2O = dioxide, 3O = trioxide, 4O = tetroxide, 5O = pentoxide, 6O = hexoxide and Ox = oxidized.
