Whole-plant absorptive-root biomass, root functional traits and mycorrhizal colonization across 74 plant species Hui Guo (25102438) Plant biology not elsewhere classified Terrestrial ecology whole plant level absorptive root biomass root economics space arbuscular mycorrhizal fungi <p dir="ltr">This dataset accompanies the study on whole-plant absorptive-root investment and root–mycorrhizal collaboration strategies. It contains individual-level measurements from 351 plants representing 74 woody and herbaceous species sampled in temperate and subtropical regions of China. The dataset integrates absorptive-root functional traits, whole-plant biomass allocation, root-system deployment, and arbuscular mycorrhizal fungal (AMF) colonization, allowing root–mycorrhizal strategies to be evaluated from the root-segment to the whole-plant level.</p><p dir="ltr">The dataset includes three main components.</p><p dir="ltr">(1) Raw data (Raw_data.xlsx), containing the original individual-level measurements used in the study, including root diameter (RD), specific root length (SRL), root tissue density (RTD), root nitrogen concentration (RN), AMF colonization rate, absorptive-root biomass (ARB), belowground biomass (BGB), aboveground biomass (AGB), and associated plant identity and grouping information. Log10-transformed versions of variables used in statistical analyses are also included. These data can be used directly to reproduce the classical root economics space analysis and selected Extended Data figures.</p><p dir="ltr">(2) Processed data after allometric correction (Processed_data_allometric_correction.xlsx), containing size-corrected individual-level variables used for the main analyses. These include allometrically corrected ARB, total absorptive-root length, total AMF-colonized root length, and the variables required for principal component analyses and correlations underlying Figs. 2 and 3 and the remaining Extended Data analyses. Allometric correction was based on residuals from log–log relationships between each whole-plant variable and aboveground biomass.</p><p dir="ltr">(3) Figure 1 source data (Source_Data_Fig1.xlsx), containing the numerical data underlying Fig. 1. Separate worksheets provide the data for allometrically corrected absorptive-root biomass allocation (Fig. 1a) and the size dependence of uncorrected absorptive-root biomass allocation relative to total plant biomass and belowground biomass (Fig. 1b,c).</p><p dir="ltr">(4) Combined script for Fig2 and 3.R — The R script Combined script for Fig2 and 3.R contains the main analytical workflow used to generate the results presented in Figs. 2 and 3. The script reads the accompanying raw and processed datasets and performs the principal component analyses (PCA), correlation analyses, and whole-plant scaling analyses used to examine relationships among root functional traits, absorptive-root biomass, root deployment, and mycorrhizal colonization. In addition to reproducing the main analyses underlying Figs. 2 and 3, the script can be used to generate the corresponding Extended Data analyses, including PCA results for different trait combinations and plant groups, as well as correlation analyses among root traits, absorptive-root biomass, total absorptive-root length, AMF colonization rate, and total AMF-colonized root length.</p> 2026-09-29T08:36:45Z Dataset Dataset 10.6084/m9.figshare.33980698.v2 https://figshare.com/articles/dataset/Whole-plant_absorptive-root_biomass_root_functional_traits_and_mycorrhizal_colonization_across_74_plant_species/33980698 CC BY 4.0
