Core and diverse ASVs across the fonio genetic population. A Histograms of the relative abundances of the top bacterial communities at genus level in the fonio genetic group (admixed, group 1, group 2, group 3, group 4, group 5, and group 6. Heat map showing over/underrepresented bacteria at genus level (B) and functional predictions across fonio accession groups (C). D The box plots show the Shannon diversity index across the genetic fonio groups where “n” is the number of samples. The box boundaries indicate the first and third quartile. Lines extending from the boxes (whiskers) indicate variability outside the lower and upper quartiles. The lines in the middle of the boxes represent the median values of Shannon index for each group. Outliers are plotted as individual points. E PCoA of 126 fonio accessions (color and shape code is based on the corresponding groups) based on unweighted UniFrac distance. F The flower diagram shows unique and core taxa with the admixed group
