Resource allocation to growth or luxury consumption drives mycorrhizal responses

Growth and functional trait data for Brachypodium distachyon grown under variable nitrogen and phosphorus supply rates and in the presence or absence of arbuscular mycorrhizal (AM) fungi.ID.Tag = unique plant identifierGenotype = Genotype of B. distachyonSalt = Salinity treatment (not manipulated here)Nutrient = Nutrient addition treatmentMycorrhizal = AM fungi added or notlane, position = pot location in glasshousePSA.fd = projected shoot area on final day (in pixels)HA.fd = hue angle on final dayAGRmax = maximum absolute growth rate (pixels/day)Dry.Shoot.Weights = dry mass of shoot (g)Dry.Root.Weights = dry mass of root (g)Fresh.Shoot.Weights = mass of shoot before drying (g)P.concentration = tissue phosphorus concentration (mg/g)N.concentration = tissue nitrogen concentration (mg/g)C.concentration = tissue carbon concentration (mg/g)Tissue.C.N.ratio = mass ratio of C to N in tissueTissue.N.P.ratio = mass ratio of N to P in tissueSupply.NP.ratio = mass ratio of available N to available P in soil SAMR = shoot area to mass ratio (pixels/g)Total.Shoot.P = total mass of phosphorus in tissue (mg)Total.Shoot.N = total mass of nitrogen in tissue (mg)RMF = root mass fractionpercent.colonisation = PC1 = ordination of plant functional traits, loadings on first axisPC2 = ordination of plant functional traits, loadings on second axisPC1.response = ordination of plant functional traits excluding N and P concentrations, loadings on first axisMGR = mycorrhizal growth response calculated from PSA on final dayFor more details, see publication (to be included).
