Comparative analyses of flavonoids in extracts from the wild type and the tt3 mutant. a The heatmaps were constructed from the average normalized intensity value of flavonoids extracted by the PCA analyses from the full data set. Hierarchical clustering analysis was performed on 20 (Ler) and 16 (tt3) metabolites with significant factor loadings in PC1 (p = 0.05) using Manhattan correlation as the distance measure. The color intensity scale is positioned below the heatmap. Starts denote: *, quercetin-3,7-dirhamnoside (f5) and **, 2′-hydroxychalcone. NE, nanoconjugate eluate; ME, methanolic extract. b, c Box plots of log10 metabolite intensity of f5 (b) and 2ʹ-hydroxychalcone (c) in the wild type (Ler) and tt3 extracts. The significance between means (n = 3) was calculated using Students t-test. Error bars represent mean standard deviation. *p < 0.05, **p < 0.005, NS, not significant
