Fig. 5

The specific metabolites and genes in the main metabolic pathways in the DH and ER overexpression strains. ER+, and DH+ represent the DH-overexpression strain and ER-overexpression strain, respectively. The red rectangle indicates key enzymes. Rectangle: DH-overexpression strain; oval: ER-overexpression strain. Red: increase (p < 0.05), green or blue: decrease (p < 0.05), white: no significant change (p > 0.05)
