Accumulation pattern of sinapine, sinapoylglucose, and sinapoylmalate in cotyledons of developing seedlings of oilseed rape. The cotyledons were harvested pairwise at 4, 8, 11, or 16 d after sowing and analyzed by UPLC-diode array detection. The graphs show the amount of metabolites in seeds and cotyledons of wild-type (WT) plants (A), of the homozygous overexpression line 1 (B; OE1), and of the homozygous overexpression line 2 (C; OE2). The data represent means ± sd of five biological replicates.
