Figure 2.

ROS level and biomolecule injuries in leaf tissue of WT and rbohd plants grown in nitrate or ammonium as a nitrogen source. (a) Leaf hydrogen peroxide concentration. (b) Membrane injury is measured as malondialdehyde content. (c) The profile of protein carbonylation in leaf tissues. Comparison tests between rbohd and WT plants were performed on the mean experimental conditions for the nitrate (light grey) or ammonium (dark grey) growth regime separately. Statistical differences calculated using one-way analysis of variance (ANOVA) with Tukey’s post hoc test are indicated at p-value ≤ 0.01 ** and p-value ≤ 0.05 *.
