Analyses of Tetracladium OTU distribution in the bulk soil, the rhizosphere, and the roots. A Observed OTU richness in the three sampled compartments. Error bars represent standard error. B Ternary plots of Tetracladium OTU distribution across compartments. C Linear regression line fitted between OTUs and yield across the three compartments with significance values. OTU relative abundances and yield are normalised. The shaded region represents the 95% confidence limits for the estimated prediction
