Complementation of the Arabidopsis grxs15-3 mutant with UBQ10pro:GRXS15 K83A. A, 8-d-old WT seedlings compared with GRXS15 K83A mutants grown on vertical agar plates under long-day conditions. B, Primary root length of 8-d-old GRXS15 K83A mutants compared to WT (n = 35; means ± sd). Different letters indicate significant differences between the different lines; P ≤ 0.05; (one-way analysis of variance (ANOVA) with post hoc Holm–Sidak analyses ). C, Germination rate of GRXS15 K83A lines #3 and #4 compared to WT. All seeds were initially stratified at 4°C in the dark for 1 d (n = 6 with 20–25 seeds each; means ± sd). Germination was assessed with the emergence of the radicle. No statistically significant differences were found using Student’s t test analysis (P > 0.05).
