Maize ATR plays a predominant role in the response to γ-irradiation-induced DNA damage. A and B, Representative 7-day-old ATR (A) and ATM (B) WT and mutant seedlings grown under control conditions (no treatment) or γ‐irradiated at doses of 75, 250, or 500 Gy on day 2. Scale bar = 6.5 cm. C and D, Average root (C) and shoot (D) length of ATR WT and mutant seedlings. E and F, Average root (E) and shoot (F) length in ATM WT and mutant seedlings. Values are average ± se; n = 25–31 (C-D); n = 24–32 (E-F). Letters on the bars indicate statistically different means (P < 0.05, ANOVA mixed model analysis, Tukey’s correction for multiple testing).
