Effect of prolonged moderate-high temperature on root elongation of Col-0, act7-4, and act8-2 mutants. (A) Phenotype of primary root elongation of Col-0, act7-4, and act8-2 for 3 consecutive days at 23 °C and 29 °C. Root elongation was marked after every 24 h (Scale bar = 10 mm). (B) Primary root elongation of Col-0 for 3 consecutive days at 23 °C and 29 °C. (C) Primary root elongation of Col-0, act7-4, and act8-2 in percentage for 3 consecutive days. Percentage root elongation at 29 °C is calculated against the root elongation at 23 °C for each genotype. Five-day-old seedlings were transferred to new agar plates and subjected to high-temperature treatment (29 °C) and control temperature (23 °C) for 3 days under light condition. Vertical bars represent mean ± SE of the experimental means from at least three independent experiments. Asterisks represent the statistical significance as judged by the Student’s t-test (* p < 0.05; *** p < 0.001).
