Expression of BrMYL2.1 and other anthocyanin regulatory and biosynthetic genes under various cultivation conditions in green and purple Chinese cabbage. (A) Relative transcript levels of the anthocyanin regulatory genes. (B) Relative transcript levels of the anthocyanin biosynthetic genes. G, green Chinese cabbage; P, purple Chinese cabbage. Results represent the means ± SD from three independent biological replicates. BrEF1α was used as the reference gene. Different letters indicate significantly different values (p < 0.01), as determined by two-way ANOVA followed by Duncan’s multiple range tests.
