title: The covariation between soil microbial communities and multidimensional fine-root economics space

description: The data is for the purpose of testing the covariation of plant root
 strategy and microbial community. It contains data on in situ
 root exudation, root chemical and morphological traits across 15 tree
 species in a tropical common garden in southwestern China. We further
 performed analyses on phospholipid fatty acid and high-throughput amplicon
 sequencing to estimate the fungal-to-bacterial ratio and diversity of
 bacterial community in the soils corresponding to target trees. There are
 three data files in this dataset. One is the "bacterial communities
 OTU.csv", which contains the original OTU data of bacteria across the
 3 replicates of 15 tree species. The
 "bacterial_abundance(Phylum)&tree_species.csv" file
 contains the annotated bacterial Phylum of 3 replicates of 15 target tree
 species. The
 "root_traits&microbial_biomass&bacterial_diversity.xlsx" file contains the fine-root traits, Total PLFA, fungal-to-bacterial ratio, bacterial stress, and bacterial diversity data of 15 tree species with 3 replicates.

 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. ### Files and variables #### File: bacterial_abundance(Phylum)_tree_species.csv **Description:** It contains the annotated Phylum of the bacterial community. ##### Variables Species name refers to the Latin name of the 15 target woody species. Replication shows the replicate number of a certain root or corresponding root sample from an individual tree of the target species. #### File: bacterial_communities_OTU.csv **Description:** It contains the original OTU of the bacterial community. ##### Variables Species name refers to the Latin name of the 15 target woody species.\ Replication shows the replicate number of a certain root or corresponding root sample from an individual tree of the target species. #### File: root_traits_microbial_biomass_bacterial_diversity.xlsx **Description:** It contains the data of measured root traits and microbial community data estimated by PLFA and high-throughput sequencing. ##### Variables Species name refers to the Latin name of the 15 target woody species.\ Replication shows the replicate number of a certain root or corresponding root sample from an individual tree of the target species.\ The units are listed below: \ Root nitrogen content, percent.\ Root tissue density, mg cm ^-3^\ Root diameter, mm,\ Specific root length, cm mg ^-1^\ Root exudation rate mgC g ^-1^ root h ^-1^\ Total PLFA, nmol g ^-1^ soil ## Access information Other publicly accessible locations of the data: * N.A.
