Linking root phosphatase activity to root chemical and morphological traits across species: a global analysisGukailin Ao,1 Changlin Xu,1 Xudong Wang,1 Mengguang Han,1 Biao Zhu1,2*1 State Key Laboratory of Vegetation Structure, Function and Construction (VegLab), Ministry of Education Key Laboratory of Earth Surface Processes, and College of Urban and Environmental Sciences, Peking University, Beijing, China.2 Ministry of Education Key Laboratory of Ecology and Resource Use of the Mongolian Plateau, Inner Mongolia Key Laboratory of Grassland Ecology, and School of Ecology and Environment, Inner Mongolia University, Huhhot, China.Title: Linking root phosphatase activity to root chemical and morphological traits across species: a global analysisPublication: New PhytologistAuthor: Gukailin Ao, Changlin Xu, Xudong Wang, Mengguang Han,Biao ZhuEmail:[e-mail]1 RPAdata_complete_clean.xlsx: Dataset containing root phosphatase activity (RPA) and associated root traits. RPA values originally measured on a fresh root mass basis were converted to a dry root mass basis using root dry matter content (RDMC).2 Rcode_analysis.R: R script used for data processing and statistical analyses.3 RPA_tree.final.tre: Phylogenetic tree used for the phylogenetic comparative analyses in this study.Please note a correction to the RPA unit: the correct unit is μmol g-1 DW h-1, though it was incorrectly documented as μmol mg-1 DW h-1 in the README sheet of the data file "RPAdata_complete_clean.xlsx". （2026-3-4）
