Figure 3. Phytochemical analysis of methanolic extracts of seedlings in WT, EV and different transgenic lines.

(a) Measurement of total polyphenol content by gallic acid equivalent. (b) Total flavonoid content by quercetin equivalent. (c) Antioxidant activity by trolox equivalent. Data are expressed as means ± SE of at least 3 independent experiments, each experiment consisting of 3 technical replicates. *** indicate values that differ significantly from WT at P < 0.001, according to Student's paired t-test.
