Differentially accumulated metabolites (DAMs) analysis. LR: L. regale, LH: L. henryi, LL: L. lancifolium, LDW: L. davidii var. willmottiae, LBV: L. brownii var. viridulum. (A) Bar graph of up- and downregulated DAMs from pairwise comparisons. (B) Venn graph for DAMs from the pairwise comparisons of traditional medicine and food used lilies (LL vs. LDW, LL vs. LBV and LDW vs. LBV). (C) Venn graph for DAMs from the pairwise comparisons between LH and three traditional medicine and food used lilies (LL vs. LH, LH vs. LBV and LH vs. LDW). (D) Venn graph for DAMs from the pairwise comparisons between LR and three traditional medicine and food used lilies (LL vs. LR, LR vs. LBV and LR vs. LDW). (E) Top 20 enriched KEGG pathways of DAMs in LL vs. LH. (F) Top 20 enriched KEGG pathways of DAMs in LL vs. LR.
