Supplementary Table 2. Significance of the main experimental factors (Treatment, Origin and Soil), and their interactions, after running a non-parametric ANOVA on the values from the linear mixed model fitted for each response variable of T. officinale ; survival (%), biomass (g) and flower production (n). The experiment included seedlings from two origins (France [native] and Chile [introduced]) growing on native or introduced substrates (soil factor), under three soil microbiome treatments: control (M+), sterilized (M-) or sterilized and reinoculated (Mr). Bold probability values indicate significant (p < 0.05) effects of treatments on survival. d.f. : degrees of freedom, F : F-statistic, p -value: probability value.
