Integrative metabolomic and transcriptomic analysis of phenylpropanoid, flavonoid, and terpenoid biosynthesis pathways. A The results of correlation analysis between differentially expressed genes (DEGs) and differentially expressed metabolites (DEMs) (p ≤ 0.05). The red dots and squares represent upregulated DEGs and DEMs, respectively, while the green dots and squares represent downregulated DEGs and DEMs, respectively. B Genes and metabolites in the phenylpropanoid biosynthesis pathway were modulated by polyploidization. The red and green words indicate upregulated and downregulated genes or metabolites, respectively. A mix of upregulation and downregulation for the gene is represented in blue, and values in parentheses represent the gene number
