Effect of light intensity on growth of Arabidopsis lines lacking type-f Trxs under a short-day photoperiod. (A) Representative plants of the wild type and mutant lines grown under short-day conditions (8/16h light/dark) for 34 d at increased light intensities, as indicated. (B) The weight of the rosette leaves from all lines was determined from 12 plants. (C) Chlorophyll content was determined from leaf discs (n=6). Average values ±SD are represented. Letters indicate significant differences with the Tukey Test and a confidence interval of 99%.
