Fig. 2From: Metabolome and transcriptome profiling revealed the enhanced synthesis of volatile esters in Korla pearCorrelation network analysis and the distribution of pear metabolites a: The metabolites contents of pear cultivars including primary metabolites and volatile substances. b: Correlation network analysis of pear cultivars based on metabolites. AA1-7 represent amino acid; A1-4 represent organic acid; S1-7 represented soluble sugar in Table S4, and V1-144 represent volatile compounds in Table S5. All correlations were at the level of r > 0.95 and P < 0.001Back to article page
