The ntrc mutant phenotype is suppressed by decreased levels of 2-Cys Prxs under abiotic stress treatments. (A) WT and mutant lines, as indicated, were grown on soil under short-day photoperiod for 8 wk, incubated for 5 d under continuous darkness, and recovered under short-day conditions for 7 d. (B) The maximum PSII quantum yield, determined as Fv/Fm ratio, was measured in dark-adapted leaves of plants grown under short-day photoperiod for 8 wk or incubated for 3 d in continuous darkness. The Fv/Fm values are represented as average values ± SE of at least 10 measurements from different plants. (C) WT and mutant lines, as indicated, were grown for 11 d on Murashige and Skoog synthetic medium containing 0.5% (wt/vol) sucrose in the absence (mock) or presence of 0.025 μM methyl viologen under long-day photoperiod. Root length, determined from at least 30 seedlings, is shown as average values ± SE. Letters indicate significant differences by Student’s t test at 99% (B) or 95% (C) CI.
