Identification of differential metabolites. (A) Volcano map of differential metabolites. Significantly differentially expressed genes are shown as a red (up) or green (down) dot. (B) Heatmap of differential metabolites. The red and blue colors represent up-regulation and down-regulation, respectively. (C) Five candidate DEGs that enriched in KEGG pathways. The red and blue colors represent up-regulation and down-regulation, respectively. W, The wild-type strain; C, the artificially cultivated mushroom strain.
