Cold-induced differential metabolites in the hepatopancreas, intestine, and muscle of G. przewalskii. The top 10 up- and 10 downregulated metabolites in the hepatopancreas (A), intestine (B), and muscle (C). The upregulated metabolites are represented by red bar and the downregulated metabolites are represented by green bar. Volcano plots indicate the significant up- and down regulated metabolites in the hepatopancreas (D), intestine (E), and muscle (F), respectively. The top up- and downregulated metabolites are shown in orange or green spots, respectively
