DATASET: Host filtering, not competitive exclusion, is the main driver of arbuscular mycorrhizal fungal community assembly under high phosphorus

We conducted a factorial pot experiment where sorghum (<em>Sorghum bicolor</em>) was grown under three different P treatments (low, medium, high), in the presence or absence of a natural AM fungal community. By analysing the diversity and community structure of the fungal communities colonising roots, we aimed to determine if and how soil P influences the relatedness of these communities and whether competitive exclusion or environmental filtering play a more significant role in their assembly. Additionally, we evaluated the concomitant outcomes for plant growth, nutrient acquisition, and defensive chemistry (phenolics).
