AB  - INTRODUCTION: The seed-associated microbiome has a strong influence on plant 
      ecology, fitness, and productivity. Plant microbiota could be exploited for a 
      more responsible crop management in sustainable agriculture. However, the 
      relationships between seed microbiota and hosts related to the changes from 
      ancestor species to breeded crops still remain poor understood. OBJECTIVES: Our 
      aims were i) to understand the effect of cereal domestication on seed endophytes 
      in terms of diversity, structure and co-occurrence, by comparing four cereal 
      crops and the respective ancestor species; ii) to test the phylogenetic coherence 
      between cereals and their seed microbiota (clue of co-evolution). METHODS: We 
      investigated the seed microbiota of four cereal crops (Triticum aestivum, 
      Triticum monococcum, Triticum durum, and Hordeum vulgare), along with their 
      respective ancestors (Aegilops tauschii, Triticum baeoticum, Triticum 
      dicoccoides, and Hordeum spontaneum, respectively) using 16S rRNA gene 
      metabarcoding, Randomly Amplified Polymorphic DNA (RAPD) profiling of host plants 
      and co-evolution analysis. RESULTS: The diversity of seed microbiota was 
      generally higher in cultivated cereals than in wild ancestors, suggesting that 
      domestication lead to a bacterial diversification. On the other hand, more 
      microbe-microbe interactions were detected in wild species, indicating a 
      better-structured, mature community. Typical human-associated taxa, such as 
      Cutibacterium, dominated in cultivated cereals, suggesting an interkingdom 
      transfers of microbes from human to plants during domestication. Co-evolution 
      analysis revealed a significant phylogenetic congruence between seed endophytes 
      and host plants, indicating clues of co-evolution between hosts and 
      seed-associated microbes during domestication. CONCLUSION: This study 
      demonstrates a diversification of the seed microbiome as a consequence of 
      domestication, and provides clues of co-evolution between cereals and their seed 
      microbiota. This knowledge is useful to develop effective strategies of 
      microbiome exploitation for sustainable agriculture.
