Extended Data Fig. 2: Comparative metabolome analysis of two morphs of Corydalis hemidicentra.

a, PCA score plot of metabolism. b, OPLS-DA score plot of metabolism, the horizontal axis represents the predicted principal component score of the first principal component, and the vertical axis represents the orthogonal principal component score. c, KEGG enrichment of differentially expressed metabolites (DEMs). VIP ≥ 1 and P_value < 0.05 indicate important differences in metabolites between the morphs. Enrichment P values are from Fisher’s exact test. d, Heatmap showing the abundance patterns of 16 differentially expressed (mean metabolism level ≥ 0.1) flavonoid metabolites identified by wide-targeted metabolomics, with the columns showing results from three replicates for each of the morphs. e, Eight anthocyanins showing differential accumulation between green and reddish grey leaves. Data represent the mean ± SD from four replicates. P values are from two-sided Student’s t test.
