Figure 6.

Comprehensive analysis of the rhizosphere microbiome at the phylum level and metabolomic profiles in D7 vs. D6. Correlation plot showing the association among components (A). The top right graph illustrates the distribution of metabolite samples. The bottom left graphic illustrates the correlation coefficient of the sample distribution. Analysis of the network relationship (B). The highest correlations between metabolomics and the microbiota were identified. Squares represent metabolites, while circles indicate microbes. The color of the line reflects the correlation coefficient. Hierarchical cluster analysis of the connection between metabolites and microorganisms (C). The horizontal axis represents the microorganisms, and the vertical axis shows metabolites. Red denotes a positive connection, while blue signifies a negative correlation. The intensity of color reflects the degree of association. * p ≤ 0.05; ** p ≤ 0.01; and *** p ≤ 0.001.
