Fig. 1From: Soil origin and plant genotype structure distinct microbiome compartments in the model legume Medicago truncatulaBacterial diversity metrics (a) and abundance (mean ± SE) of the most abundant bacterial OTUs (b) for the four compartments studied. All estimates are based on iterative subsampling (1500 sequences per iteration at 1000 iterations). Letters represent significant differences (Tukey HSD) across compartmentsBack to article page
