AtCHR23 over-expression only affects root length in sufficient light. (A) Mean (± SD) root length of wild-type (Col) and mutant seedlings grown for 10 days at 23°C in continuous light. (B) Mean (± SD) root and hypocotyl length of 10-day-old wild-type (Col) and mutant seedlings grown at the indicated temperature in the dark. (C) Mean (± SD) root and hypocotyl length of 10-day-old wild-type (Col) and mutant seedlings grown at 23°C in short-day conditions. For each line 40 seedlings were measured. Asterisks indicate significant differences from the wild type: ^***, P < 0.001.
