Levels of O₂^•− generation (Δ<i>A</i>₅₄₀ min⁻¹ g⁻¹ fresh weight) in leaves of the maize seedlings colonized with <i>R. padi.</i>

Values are the means ± standard deviation (SD) of three independent experiments (10 plants per repeat); hpi-hours post-initial insect infestation; the different letters in rows denote significant differences according to Tukey's test (P≤0.05).
