Metabolome analysis of oysters with high glycogen and low glycogen. a Metabolic profiles of high- and low-glycogen content oysters visualized by principal component analysis. The points represent the scores of biological replicates. b Heat map of all identifiable metabolites in Pacific oyster tissues comparing the high-glycogen group with the low-glycogen group. Columns represent biological replicates (n = 10 per group), and rows represent individual metabolites. The more abundant metabolites in the high-glycogen content oysters appear red, and the more abundant metabolites in the low-glycogen content oysters appear blue. The dendrograms denote the overall similarity of metabolite expression profiles (y-axis, left). c Pathway analysis for the identified metabolites in high- and low-glycogen content oysters. A row represent the enriched pathways and boxes correspond to difference in the relative abundance between high- and low-glycogen content oysters (metabolites more abundant in the high-glycogen content oysters appear red, and blue represents a more abundant metabolite in the low-glycogen content oysters). Total represent the total number of metabolites in the pathway and hits show the number of metabolites in the pathway significantly different between the two groups. d Statistical significance and pathway impact of the pathway analysis with MetaboAnalyst 3.0
