Fig 2. Compositions of phospholipids and oxidized lipids in Arabidopsis rosettes upon 48-h and 96-h hypoxia exposure.
(A) Contents of different molecular species of membrane lipids (MGDG, DGDG, PG, PC, PE, PI, PS and PA) in 4-week-old wild-type Arabidopsis before treatment (Control) and at 48 h (Light Sub48 h) and 96 h (Light Sub 96 h) after light submergence treatment. (B) Amounts of oxidized membrane lipid species (MGDG-O, DGDG-O, PG-O, PC-O and PE-O) as well as complex arabidopsides (ArA, ArB, ArC, ArD and ArE-type) in 4-week-old wild-type Arabidopsis before treatment (Control) and at 48 h (Light Sub 48 h) and 96 h (Light Sub 96 h) after light submergence treatment. a, indicates value of Light Sub 48 h or Light Sub 96 h higher than that of Control; b, indicates value of Light Sub 48 h or Light Sub 96 h lower than that of Control (*P<0.05 or **P<0.01 by Student’s t-test). Values are the means ±SD (n = 4). Control refers to samples harvested from plants grown under the same conditions before treatment.
