Figure 1. ERF6 gene expression relative to actin genes analyzed by qRT-PCR after spraying 4-week-old soil grown Arabidopsis (WT, Col-0) plants with H₂O₂ (3h) or paraquat (2h).

Three independent biological replicates (20 plants each) were used for each treatment. Error bars represent standard deviations. Asterisks indicate significant (P<0.05) differences in treated plants compared to mock-treated plants.
