Table 1 The dependence of AM fungal colonization and plant mass on population origin (China or US), time (categorical variable: 60 or 90 days), and their interaction as fixed effects and population nested in origin as a random effect in the common garden experiment.

From: Increasing flavonoid concentrations in root exudates enhance associations between arbuscular mycorrhizal fungi and an invasive plant
