Description of the data and file structure

We measured root exudation and other chemical and morphological fine-root traits across 15 tree species in a tropical common garden in southwestern China. We used phospholipid fatty acid analysis and high-throughput amplicon sequencing to estimate the fungal-to-bacterial ratio and diversity of the bacterial community in the soils corresponding to target trees.

In the data files, the "microbial_abundance (PCoA).xlsx" contains the microbial abundance data of 15 tree species with 3 replicates, which can be used for Principal Coordinate Analysis (PCoA) and Permutational Multivariate Analysis of Variance (PERMANOVA). The "root traits and bacterial communities OTU (Mantel test).csv" contains the fine-root traits and bacterial abundance data of 15 tree species with 3 replicates, which can be used for the Mantel test. The "bacterial_abundance(Phylum)&tree_species.csv" contains the bacterial abundance data (Phylum) of 15 tree species with 3 replicates, which can be used for Redundancy Analysis (RDA). The "root_traits&microbial_biomass&bacterial_diversity.xlsx" contains the fine-root traits, Total PLFA, fungal-to-bacterial ratio, bacterial stress, and bacterial diversity data of 15 tree species with 3 replicates, which can be used for the Principal Component Analysis (PCA) and standardized major axis regression model.
