Fig. 7From: An R3-MYB repressor, BnCPC forms a feedback regulation with MBW complex to modulate anthocyanin biosynthesis in Brassica napusRegulatory relationships between BnCPC and the anthocyanin activators. A–C The expression pattern of BnCPC, BnPAP1, BnTT8, and BnEGL3 under anthocyanin inducible (cold and light) and non-inducible (dark) growth conditions. Expression levels were standardized to B. napus Actin-7 (NC_027775.2), and the expression levels of BnCPC before treatment were set at 1. Values represented the mean ± SD (n = 3). D Dual-luciferase assays of BnPAP1, BnTT8, BnEGL3, BnPAP1 + BnTT8/BnEGL3, and BnCPC + BnPAP1 + BnTT8/BnEGL3 effects on the activity of BnCPC promoter. Values represent the mean ± SD (n = 6). Different letters represented statistically significant differences (one-way ANOVA, p < 0.05)Back to article page
