Biplot of total and constituent anthocyanin contents and the expression of anthocyanin biosynthesis pathway genes in four Brassica lines (Asia, Rubea, Rs035, and Rs306), determined using a principle component analysis (PCA). Genotype text color reflects the visual phenotype of the leaves. Blue and italic texts denote anthocyanin components and gene names, respectively. C3-dig5-gl cyanidin 3-diglucoside-5-glucoside, C3-s-dig5-gl cyanidin 3-(sinapoyl)-diglucoside-5-glucoside, C3-sop5-m.gl cyanidin 3-sophoroside-5-malonylglucoside, Mal3-(p-c)gl py de malvidin-3-(p-coumaroyl)glucoside pyruvic derivative, Pe3-(6-ac)-gl pelargonidin-3-(6-acetyl)-glucoside, C3-(p-c)digl5-gl cyanidin 3-(p-coumaroyl) diglucoside-5-glucoside
