Transgenic ArabidopsisCaPMEI1-OX lines exhibit tolerance to oxidative stress. a Effects of methyl viologen on the seed germination of transgenic lines. Seeds from wild-type, vector control and transgenic lines were plated on media with or without methyl viologen (MV, 5 and 10 μM) and incubated for 3 days. The data represent mean ± SD of 100 seeds for each line tested. b Phenotypes of wild-type, vector control and transgenic line seedlings treated with different concentrations of MV. c Fresh weights of seedlings grown in the indicated concentrations of MV for 2 weeks. The results are presented as the average fresh weight per seedling. Data represent mean ± SD from three independent experiments. d Chlorophyll content of MV-treated leaves of wild-type, vector control and transgenic plants, which were floated on 0, 0.05, 0.1 and 0.5 μM MV in MS medium and then incubated for 24 h in a growth chamber
