  1. *Numbers denote for relative abundance (%) in seeds of each plant genotype. Taxonomy was assigned at species level to core OTUs using NCBI BLAST alignment tool
  2. **Percentage of OTUs occurring in all replicates of the respective plant species, while being absent in the core microbiomes of all other plant species
