Over-expression of AtCHR23 leads to overall reduced seedling and plant growth. (A) Mean (± SD) cotyledon area of 8-day-old wild-type (Col) and mutant seedlings grown at 25°C in long day conditions. (B) Mean (± SD) of hypocotyl length of wild-type (Col) and mutant plants grown for 8 days at 25°C or 28°C in long-day conditions. (C) Mean (± SD) leaf area of first rosette leaf of 15-day-old soil grown wild-type (Col) and mutant plants in long- day conditions. (D) Mean (± SD) rosette diameter of 4-week-old wild-type (Col) and mutant plants grown as in (C). For each line, 40 seedlings or 15 plants were measured. Asterisks indicate significant differences from the wild type: ^**, P < 0.01; ^***, P < 0.001.
