Figure 4
CCA analysis of soil properties correlated with the soil microbial communities and metabolites of sugarcane. (A) Correlation between the content of soil properties and the relative abundance of the top 18 soil differential microbes at the genera level (black dot corresponds to a bacterial genus). (B) Correlation between the content of soil properties and 22 distinct metabolites of sugarcane stalk. Vectors show the relationship between the secondary variables and the microbial community data, where the length and angle are determined by the correlation of each variable with the ordination axes. ‘pH’, ‘C’, ‘N’, ‘P’, ‘K’, and ‘Na’ refer to soil properties. Figures were produced using R (v3.4.3, https://www.R-project.org).
