Expression of Flavonoid Biosynthetic and Regulatory Genes.

(A) Expression of flavonoid biosynthetic genes. Anthocyanin biosynthetic genes are labeled in red. Expression level in the wild type (Wt) was set to 1. Errors bars indicate ± se (n = 3). Two biological replicates were analyzed, with similar results.

(B) Expression of flavonoid regulatory genes.

Two-centimeter-long stems above the rosette were harvested and subjected to qRT-PCR analyses. Errors bars indicate ± se (n = 3). Two biological replicates were analyzed, with similar results.
