Table 1 Results from modified principal variance component analysis (PVCA) enumerating the amount of community variation explained by soil origin (France of Corsica), plant genotype (G1, G27, G96), plant compartments (rhizosphere, root, nodule, leaf) and all possible interactions. Further, diversity estimator ANOVA results are presented across the same design. Complement of Simpson’s Diversity and Evenness were transformed using logit transformation and richness was transformed using Box-Cox functions prior to analysis
