Database of Multi Organ Functional Trait Associations for Woody Legumes Across Mycorrhizal Types

Species scientific names were standardized and verified according to The Plant List. The mycorrhizal symbiotic types of species were cross‑validated using multi‑source databases and publications. After quality control procedures including record screening, unit unification, outlier identification and standardized treatment of missing values, we constructed a database of multi‑organ functional trait associations for woody legumes across different mycorrhizal types. The dataset consists of three core Excel spreadsheets that record aboveground functional traits (leaf, stem, seed and wood) and belowground root functional traits of woody legumes.

Species are labelled with five mycorrhizal categories: AM, ECM, mixed AM‑ECM, NM and uncertain. A complete metadata document is also provided. This dataset fills the gap of legume‑specific datasets linking multi‑organ traits and mycorrhizal types. It can supply standardized basic data for studies on functional trait trade‑offs of legumes, plant‑microbe symbiotic interactions, large‑scale comparative ecology, parameterization of ecological models, and species screening for vegetation restoration in degraded lands.
