Expression analysis of BrCAO and enzyme assay of BrCAO. (a) The expression pattern of BrCAO in leaves of four stages (cotyledon, seedling, rosette, and heading stage) in pale green mutant (pgm) and wild-type (FT). (b) The CAO activity in pgm and FT. U/L = activity unit. The ‘*’ represents significant differences at 5% levels.
