Table 3 The effects of eCO₂ and soil depth on the functional and phylogenetic structure of soil microbial community by non-parametric permutational multivariate analysis of variance (PERMANOVA) with the adonis function. The functional structure data were based on all detected genes by GeoChip while the phylogenetic structure data were based on gyrB only. R² value is the constrained percentage of the parameter
