FIGURE 4 Correlation analysis of the soil microbial community and environmental factors. A and B, RDA of the bacterial and fungal community at the genus level and environmental factors in rhizosphere soil. The different shapes of the points represent different families. The green and red arrows indicate the genus and the environmental factor, respectively. C-D, Analysis of the correlations between rhizosphere soil bacteria and fungi and environmental factors in the heatmap. Pearson coefficients were used to evaluate the correlations between environmental factors and selected genera (the 10 with the highest relative abundances). R values are shown in different colors in the diagram. For each genus, White, red and blue indicates no change, increased abundance, and decreased abundance, respectively.
