Extended Data Fig. 1: Microbiota composition of SynCom-137 and plant phenotype in presence and absence of Xanthomonas Leaf131.

a) Principal component analysis of SynCom-137+Xanthomonas Leaf131 and of b) SynCom-137 in Col-0 (blue), rbohD (green) and rbohD/RBOHD (light blue). Axes show principal components PC1 and PC2 with their explained variance (%). Statistical analysis (PERMANOVA) analysis is represented by effect size shown in Fig. 1Ac) Heatmap shows log2 fold changes (log2FC) of strains in SynCom-137 in rbohD or rbohD/RBOHD compared to Col-0 wild-type plants in the presence (+) or absence (-) of Xanthomonas Leaf131. Black rectangles show significant changes, p-value < 0.05 (n = 16, two-sided Wald test, Benjamini–Hochberg adjusted). Subset of same data is shown in Fig. 1b. d) Plant phenotype of Col-0 (blue arrow), rbohD (green arrow) and rbohD/RBOHD (light blue arrow) mock inoculated or with SynCom-137 or SynCom-137+Xanthomonas Leaf131. Two representative replica growth boxes are shown for each treatment.
