Fig. 1From: Potato root-associated microbiomes adapt to combined water and nutrient limitation and have a plant genotype-specific role for plant stress mitigationMicrobial diversity of potato plants. Beta-diversity of the 166 potato-associated microbiota is shown in a non-metric multidimensional scaling (NMDS) ordination based on the Bray–Curtis distance according to sample type (shape of the symbols) and stress (colour) (A, D). Samples with similar composition cluster. Significance was calculated using a permutation test. Alpha-diversity indicated (B, E) by the Shannon index and (C, F) the number of different ASVs, the richness of a sample. Significance was determined by Wilcoxon-tests. * <  = 0.1, ** <  = 0.05, *** <  = 0.01 NS = not significantBack to article page
