Fig. 1: Metabolome and transcriptome analyses of differently colored mulberry fruits.

a Three representative cultivars with typical colored fruits. b PCA score plot of metabolite profiles of CS (yellow), BYW (white), and HG2 (purple) mulberry fruits. c OPLS-DA loading plots for different mulberry cultivars. d Hierarchical clustering of flavonoid metabolites in CS, BYW, and HG2 fruits. Intensity values were adjusted by log transformation and then normalized. Flavones, flavonols, and anthocyanins with significant differences in abundance among differently colored fruits are indicated in yellow, blue, and red text, respectively. e PCA score plot of transcript profiles from CS, BYW, and HG2 fruits
