Enhanced oxidative stress tolerance of DREB2C overexpressors. (A) Changes in DREB2C transcript levels in response to oxidative stresses. RT-PCR analysis was used to determine mRNA transcript levels. Two-week-old plants were exposed to 10 μM MV for the indicated periods of time. Arabidopsis Actin2 (At3g18780) served as a control. (B) Two-week-old plants (wt and DREB2C overexpressors) grown at 22°C were exposed to 0.5 μM MV for the indicated time periods. Scale bar = 0.5 cm. (C) Ion leakage, an indicator of oxidative stress tolerance, was estimated as a percentage of total conductivity. Two-week-old plants grown at 22°C were exposed to 0.5 μM MV for the indicated periods of time. (D) PSII activity (Fv/Fm) was measured at 22°C after adaptation to the dark for 30 min. Two-week-old plants grown at 22°C were exposed to 0.5 μM MV for the indicated periods of time. Data represent the means ± SE of at least five independent experiments.
