Fig. 2: Flavonoids mediate variations in rhizosphere microbial diversity and community composition of wild-type Micro-Tom tomato in natural soil.
From: Flavonoid-mediated bacterial spermidine biosynthesis enhances vitamin accumulation in tomato fruits
A, B Bacterial richness (Chao1) and diversity (Shannon) under combined and individual flavonoid treatments. D, E Fungal richness (Chao1) and diversity (Shannon) under different flavonoid treatments. Tops and bottoms of boxes represent 25th and 75th percentiles, respectively. Horizontal bars within boxes denote medians, and the upper and lower whiskers represent the range of non-outliers. Different letters above the error bars indicate significant differences between treatments. All plots are mean ± SEM (n = 3 biological replicates, one-way ANOVA with correction by Tukey’s HSD test, P < 0.05). C, F Bacterial and fungal beta-diversity revealed by principal coordinate analysis (PCoA) based on unweighted UniFrac distances. G List of rhizosphere biomarkers in planted soil identified by linear discriminant analysis (LDA) effect size (n = 3 biological replicates). H List of rhizosphere biomarkers in unplanted soil (n = 3 biological replicates). Flavonoids were applied in combination (rutin: naringenin chalcone: kaempferol-3-O-rutinoside = 1:1:1, m/m/m; A: 10 µmol g−1, B: 3 µmol g−1, C: 1 µmol g−1 and D: 0.1 µmol g−1) and individually (N: naringenin chalcone, 1 µmol g−1; R: rutin, 1 µmol g−1; and K: kaempferol-3-O-rutinoside; 1 µmol g−1). Wild-type (Con) and SlMYB12-overexpressing (O) plants served as controls. P-values are shown in source data. Source data are provided as a Source Data file.
