Plant soil feedback (PSF) between host plant species

See SI Appendix Materials and Methods for a description of the PSF experiment. Focal species - host plant species that served as the focal plant in the PSF experiment. Soil C Species - host plant species that served as the soil conditioning plant in the PSF experiment. Contrast - pair of focal and soil conditioning plant species. Biomass ratio - plant soil feedback measured using total biomass. AGB ratio - plant soil feedback measured using only aboveground biomass. BGB ratio - plant soil feedback measured using only belowground biomass. Mean Gen Dist X - patristic (phylogenetic) distance between focal and soil conditioning host plant species. Mean Fun Dist X - phenotypic distance between focal and soil condition host plant species. Endo Wu W - the average weighted UniFrac distance between endosphere compartments of focal and soil conditioning host plant species. Rhizo Wu W - the average weighted UniFrac distance between endosphere compartments of focal and soil conditioning host plant species. Endo Uu W - the average unweighted UniFrac distance between endosphere compartments of focal and soil conditioning host plant species. Rhizo Uu W - the average unweighted UniFrac distance between endosphere compartments of focal and soil conditioning host plant species
