Fig. 1: Barley microbiota composition displays a quantitative variation in a segregating population between wild and elite parental lines.

a Ternary plot depicting microbiota composition in the elite and wild genotypes as well as bulk soil samples. Each dot illustrates an individual ASV; the size of the dots is proportional to ASV’s abundance while their position reflects the microhabitat where bacteria were predominantly identified. Individual dots are colour-coded according to their significant enrichment in the rhizosphere of either parental line (Wald Test, Individual P-values < 0.05, FDR corrected). b Canonical Analysis of Principal Coordinates computed on Bray–Curtis dissimilarity matrix. Individual dots in the plot denote individual biological replicates whose colours depict sample type in the bottom part of the figure. The number in the plot depicts the proportion of variance (R²) explained by the factor ‘Sample’ within the rhizosphere microhabitat, i.e., Elite, Wild or Segregant. The asterisks associated to the R² value denote its significance, P-value ‘Sample’ = 0.001; Adonis test, F = 2.23, 5000 permutations. Source data are provided as a Source data file.
