Proportion of rhizosphere microbiota variance explained by the indicated variables and corresponding statistical significance.
| Factor | R2 | Pr(> F) |
|---|---|---|
| Weighted Unifrac | ||
| Microhabitat | 0.285 | < 0.001 |
| Eco-geographya | 0.168 | < 0.001 |
| Bray–Curtis | ||
| Microhabitat | 0.221 | < 0.001 |
| Eco-geographya | 0.129 | < 0.001 |
Levels of the factor Microhabitat are either ‘Bulk soil’ or ‘Rhizosphere’. Levels of the factor Eco-geography are the groups ‘Coast 1′; ‘Coast 2′; ‘Desert 1′; ‘Desert 2′; ‘North’; and ‘Elite’, respectively.
