Dynamics of metabolite during pear flesh development. a The pear fruits collected from 11 stages. b Principal component analysis of metabolome data in the fruit flesh at 11 stages. c Clustering analysis of metabolic profiling grouped the differentially accumulated metabolites into eight clusters, I → VIII. Z-score standardized values of each metabolite across all 11 stages were used for clustering analysis. The color bar denotes an increase in the contents of each metabolite, transitioning from blue to red color. d The number and cluster of the metabolites that were significantly increased in the next stage. S1 to S11 indicate the pear fruit at 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24 weeks after flower blooming, respectively
