Fig. 1
Assembly and diversity of rice (Oryza sativa ) root-associated microbiota under zaxinone and MiZax treatments at tillering (30 days after transplanting, T1) and milky-stage (90 days after transplanting, T2). (A-B) Average relative abundances of prokaryotes (A) and Fungi (B) at the Class level; the Phylum is indicated in brackets. (C-D) Constrained Principal Coordinate Analysis (cPCoA) plot of Bray–Curtis distances between samples by treatment of prokaryotic (C) and fungal communities (D) across the different compartments. Points represent single samples and are coloured by treatment. The fraction of the total variance explained by the projection is indicated in brackets along each axis. (E-F) α-diversity analysis (within sample diversity) based on Shannon Index of Prokaryotic and Fungal communities. Asterisks indicate significant differences between timepoints (T1 and T2) according to the Student’s t-test (* P < 0.05, ** P < 0.01, *** P < 0.001). No significant effect of the treatment was detected for both groups (Fungi and Prokaryotes) and compartments (unplanted soil and rhizosphere); the treatment p-value from Kruskal-Wallis/ANOVA analysis is indicated in the figure.
