Plain Language Summary

This paper describes the Global Root Trait Database (GRooT), which serves as a repository for plant root data collected from around the world. Roots and their characteristics can be conceptualised and measured in a variety of ways. Without a concerted effort to standardize definitions and approaches, reconciling differences between single datasets can be difficult and preclude reuse beyond their original intended purpose. This database combines the expertise from researchers in the discipline to standardize, integrate and synthesize data about roots and their characteristics in a ready-to-use format. Overall, the GRooT database contains 114,222 data entries on 38 traits considered important for describing plant form and function. It includes empirical observations from experimental and field studies as well as values derived from the scientific literature. The database cover plant species from across the world, including arid, continental, polar, temperate and tropical biomes. Maps highlighting data availability and their location of origin as well as a phylogenetic tree that describes the species represented in the database are provided. This database is a critical step to facilitate inclusion of root traits into global scale comparative studies and modelling efforts and provide valuable insight into overall plant functioning.
